View Full Version : G73JH Black screen :(

So the other night I Rebooted My G73jh, went to grab some more coffee amd came back to a Black/Blank Screen. Tested the vga out and the HDMI but no response. Called Asus and they claim they won't RMA since the 1 year manufacturers warranty is up by a couple of months, which really doesn't give me a warm fuzzy feeling about the tech support.

This is the most expensive system I've ever purchased as I usually build my own and to have the system crap out after little more than a year of light use really makes me a little perturbed.

I'm fairly familiar with builds/repair, So I've been throught the usual bit's of checking seats, Battery in/out reset. Cmos Reset. I haven't as of yet pulled the mobo but from what I've been able to see, there doesn't appear to be any burn spots, fat caps or lack of thermal paste on the GPU.

Hi

When you went for that coffee, did you close the notebook or was it open and then it was black ?

If it was closed, then it could be the magnet sensor that is stucked or something. So you'll need a magnet to get the screen to work :)

It was closed with another monitor on the vga out. There were no changes in magnet testing the closed lid sensor. :)

Hmm... so your notebook does boot up but you don't get any picture on the screen?

Could it be a faulty RAM that you're handling with then ?

EDIT: If it turns out to be a faulty RAM, take out all of them, and run one at the time so you can find out which RAM that puts an end to your system.

I tried Alternating seating of ram, single, dual, none. No changes...still a black screen. :)

1) Does the ASUS splash screen appear on the attached external monitor, or on your laptop display if you removed the external monitor?

2) Does removing everything from all ports (including the card reader), unplugging the laptop, removing the battery, holding the Power On button down for 30 seconds, then plugging in just the power adapter and restarting, display any video on the laptop display?

3) Have you tried reseating your HDD?

4) If you spam F2 on startup, can you enter the BIOS with video displayed?

I've reseated everything a few times now while trying to eliminate what the problem might have been. I get no display from any output(lcd,vga,hdmi) no post, logo's or bios.

Yemon

Unfortunately, that's my diagnosis as well. Which is really kind of sad considering this unit was touted as a "gaming laptop".

*edit:

It'd be fantastic if I could just get it rma'd and fixed(under warranty) and get back to gaming.

Info on my surprising success at bringing my G73jh back from the dead.

I did a full tear down yanked the mobo and G-card. While I've read stories of loose connections, everything on the board appeared tight and well seated.

I removed the heat sink form the G-card and found the thermal pads on the card had been put on rather sloppily so I carefully lifted and reseated them. The GPU appeared to have a bit less thermal paste than I like, so I cleaned off the parts and put a fresh bit of paste on.

While the mobo was out, I popped the mobo battery and let the mobo drain down while I cleaned and prepped the G-card.

I then re-assembled everything and tried booting it up.

While the work on the G-card may have helped, as well as reseating all the connections, I have a sneaking suspicion that pulling the battery on the mobo and letting the board drain down completely may have been the kicker. My wife's old dell laptop(from n2003) had, had a similiar situation once and I went through almost the same process on it several years ago and it's worked ever since. I can only hope that my luck in this instance, works as well since she still uses it browse forums and fb while we game.

Congratulations, Dr. Frankenstein! I find it very significant you were able to determine the problem was NOT a dead video adapter. This can help and bring some hope to others who experience a similar issue.

Yemon
03-27-2012, 06:43 PM
Well, my take on it is this...

* the cmos reset button doesn't really work like it's supposed to.
* battery out reset doesn't really work.
* the loose connection thing doesn't really seem feasible.
* the possibility may exist that the known issues with the board architecture can be possibly offset by discharging the board to regain the system os.

My question is, 'Has Asus already figured this out?"

IF we can get some confirmed unbricking on a few more of the G series Systems and the problem really is somewhere in the board architecture then Asus is going to need to do a little pr work, like sending registered owners a 1/2" hole saw, & rubber plug to mod the case and thereby making the battery easily removable(or like sending me a full padfone kit LOL ).

LOL the hole saw idea might actually work now that i think about it. Hmmm mpossible mod in my future ;)

Just received my laptop back from RMA for this same issue. black screen no asus logo but could hear windows boot if speakers were on. Received it back with a note that said issue could not be duplicated returned unrepaired. However, the system booted right up even though for weeks it would not. I'm not sure if they fixed it in a manner that would be deemed unacceptable for waranty work or if being unplugged for several days for shipping made it fix itself. I'll post back after running some games for a while to see if the issue returns and is possibly heat related or if it stays away.

That **** happened to me too. Sent it in for RMA for the second time this year..... I fear for the warranty to go out and that
something will happen again... the service kinda sucks too, i mean what the hell, why do they sell me a laptop that is already
broken

I'm going to take apart and try finding that battery to pull tomorrow. I have tried twice by email for rma and havent heard back from asus but what bothers me is i cant find the 3rd stick of ram for 12g total. thats the only 1 of course i havent reseated. I hear nothing but bad responses on rma so I may as well keep working on this with the forums.

Yemon

The third stick of ram is going to be on the 'other' side of your mobo. Good luck! :)

I know that this thread is pretty dated but I have relevant information to attach so I made an account precisely for this reason. My friend bought an Asus G73SW-A1 as a desktop replacement for gaming. He plays World of Warcraft and Diablo 3 mainly, so this laptop should have been more than he needed. Like a few other G73 owners he started to experience severe graphics issues. The Display Driver would stop responding in the middle of game play, causing the laptop to lock up and only resume after a hard restart, so he had plenty of Kernel 41 errors in his event log. Also, he would encounter Black Screens on restart. It was intermittent, but the screen would fail to start even though Windows would continue to boot unseen.

He RMAd the laptop and it was supposedly given a new Graphics Card, but the problems persisted to the point where the laptop was essentially a $2000.00 brick. It reached a point where it would boot to a Black Screen continuously, and then randomly it would boot properly all of the sudden after about 10-20 hard restarts. This was despite several Graphics driver upgrades and clean reinstalls of Windows.

I took the laptop apart for him and pulled all the connections, checked the graphics card and mobo for obvious signs of wear and damage. Everything looked good, and I could tell from my first disassembly that I was the first person to have taken the laptop apart, so I doubt whether Asus actually replaced his card, but I could be wrong.

After reassembly the laptop worked again for about two months then the problems returned. I took it apart yet again and the problems seemed to be fixed again for about a month this time. But my friend was frustrated so he finally bought a new Alienware laptop instead and gave me the fancy brick to mess around with

After a bit of internet research I came across this thread and thought I would give disassembly another try. Only this time I would pull the battery and let the mobo drain before reassembling. Im not sure if this will be a better fix than the temporary fixes Ive come across before. Along with the battery pull I cleaned up and reapplied thermal paste to the graphics card because it was done rather poorly at the factory. I cleaned the contacts with alcohol and reassembled everything. It has been only two days but so far everything seems to be working fine. I have had no display driver stops, and no Black Screens on boot. But whether the problem will stay gone or return is a matter that only time can settle. I plan on updating if the problem does return.

Also, I would be interested to hear if OP still has a working laptop or if the problem returned.

I have the exact same problem with my 1 1/2 year old Asus G73Sw. The first time it happened was around 2-3 weeks ago and unpluging and removing the battery worked. Now after 2 weeks I get the same problem again. I've only tried the battery thing and holding the Start button for 15-30 secs. I don't know what made it work but this morning after trying for an eternity it worked again.

I haven't tried reassemblying or applying more thermal paste cause I would have no idea what I'd be doing but if I get the problem again I know what needs to be done.

Yemon
09-13-2012, 08:50 PM
I Do still have the laptop. It does "run" but I"ve had continued issues with my g73 since my original post.
I've found that the only way to really keep it operational is factory defaults and old drivers. Updating anything graphics or audio related sends it into fits of uselessness that I can only seem to cure by pulling the cmos battery on the main board and letting everything reset and reverting any new drivers to original. (even with clean installs of new drivers following the official documentation)

I won't be purchasing anything Asus related again.

update on my problem:

For the past few days after I got it to work I didn't close the lid after shutting down. And I never got the black screen in the morning turning it on since then. This morning after closing the lid and opening again... BAM.. black screen. And I could hear the windows starting... After moving the laptop around and closing and opening the lid like 50 times it worked..

MissK, yours sounds like it could be a magnet sensor issue. You should be able to test this by moving a magnet around the palm rest area until you find the sensor (the screen will turn off when you hit it). I'm sorry I don't remember where it is exactly and I couldn't find a picture online so just experiment with a decently strong magnet and it will trigger when you get in the general area. Once you know where it is you should try tapping that spot with the magnet a few times when the screen goes black to see if the screen turns on.

Is it like this one? (It was for the G53, but it might work also for the G73.):

I wanted to reply in this thread also. I just had the same problem tonight. My G73Jh, which is about 2 years old now, I wasn't having any problems the night before. I shut it off normally and closed it. Tonight I opened it up, and lights came on, seemed to be booting but black screen. I tried the 'magnet sensor' thing that I saw suggested but no luck.
I do a lot of desktop repair stuff but laptops are such a pain, I really didn't want to take it apart to find out it was a bad GPU or something. I had sent Asus an email, even though I am out of the warranty but then I randomly just tried to turn it on again about 2 hours after originally trying to.
It said it had failed to start, I started windows normally and it seems fine now. However, now I am concerned as to what it might have been and if I should be worried about shutting it off again. LIke if this is going to become a normal thing. Any thoughts?

Well, while it is working I would locate the magnetic sensor. It's much easier when you can see the display blink off to know that you have the right spot. But if it's not that then it could also be a loose display cable. That would be fixable but a pain.

I can confirm that something is obviously wonky with it. Today when I went to turn it on, I had the same issue. It only worked after I spent a bunch of time opening and closing it, taking out the battery, unplugging it, turning it on and off. Its hard to tell what exactly made it turn on, but it finally did after about 10 minutes of trying. Once it is on, it works fine and never crashes or has any issues.

Problems again... I was playing Skyrim and all of a sudden it freezes. Nothing I try is working so I have to hard reboot. Once it reboots... black screen and I can't make it work.

The first time ever the black screen appeared was after a hard reboot one month ago. After windows froze while doing mostly nothing..

Unfortunately, I've yet to read about anyone recovering from the "boot to black screen" issue without a repair involving motherboard and/or VGA replacement. The workarounds of discharging the laptop or multiple reboots have only temporary effect.

@cl_scott, who has career experience in laptop repair, indicates defective capacitors can cause this problem in http://rog.asus.com/forum/showthread.php?23328-Asus-53S-Won-t-Turn-On&p=162536#post162536. This idea is supported by observations that the behavior becomes more frequentl over time.

My laptop had been fine for a month or so but tonight it suffered the same black screen as before. I happened to notice your post about removing everything, battery included, holding the power button and trying again. This time, it turned right on.
Is this a sign of bad caps and impending doom?

My G60J has the black screen since this morning, I let it open during the night connected via VGA to a Monitor and this morning i was wake-up by the FAN. Black screen was displaying, I pressed the power button, switched off the laptop and when I try to power it up, I get the black screen with no post. I have read the forum and none of the teaks and tricks worked for me. In conclusion, should I buy a new video card for this laptop or just buy a new laptop?

If you're capable of pulling out the video card you could try pulling the cmos battery on the mnotherboard for a couple of hours and seeing if that works for you. It did work for me in getting the system back up and running. I will add to that tho that you are probably on the verge of a dead laptop sooo....

My recomnedation would be purchasing a new laptop(with a different brand name). IF you're past warranty asus will tell you to take to your point of purchase or send it to a retail repair facility. Buying the video card for the g60 will run around $200+SH for aused part.

I will add my G73s screen issues to the mix and how I have been *fixing* mine. First issue I had was the screen would suddenly
drop resolution that resembled not having a graphics driver installed. Multiple restarts did not help. Out of warranty, I was getting ready to drop off at repair facility when in frustration I tapped the screen from the side and it corrected it. Each time this happens, tapping it corrects the problem. I got a black screen on boot up today and tapping it fixed the problem again. I'm assuming it is a cable connection issue but haven't dismantled it to permanently fix this. So if all the above suggestions do not fix your issue and you are ready to send in for a fix, try a tap on the side as a last resort. I know that isn't the best thing to do with computer equipment but if it is dead, what are you hurting?

12-16-2012, 07:35 AM
Well, it looks like I got myself a brick too.

I got the black screen on boot more and more often over a period of 6-8 weeks just out of warranty and now it simply has gone completely dead. I must have rebooted it 30 times to no avail. I must add that it had started seriously overheating too and got the fan going making a real racket and still managed to need to shut itself off hitting the 100C.

I have opened up the back unscrewed the dozen or so screws and start opening it up further but quickly realised that it is beyond me. I am not at all a hardware guy! I am surely not expecting to put paste or whatever on the innards of a laptop to keep it running. Not at all meeting my expectations here.

I was not using it as a game machine but it was on and slogging 16 hours/day 7 days/week.

I guess I can try to sell it for parts, the disk must still be working and it has 10G of memory.

Overall a very poor experience.

This was my first Asus and it will be my last. It is an experience I can ill-afford to repeat financially.

Ok, now to find out where is my best bet to sell it for parts. I am in Australia (Perth), any ideas about where and how much could I expect to move it fast?

BLACK SCREEN PROBLEM! SOLVED:

First of all I want to say hello to all you guys here on forum and before I start explaining how to fix this issue I want to mension what laptop I have:

ASUS G75V
Processor i7 Q3630
HDD 750GB
nVidia GTX670 MX * 3GB
8GB RAM
17.3"
WIn8

...this was configuration after I buy it. Then I decide to upgrade it with +8GB of RAM and one 120GB SSD as a C: drive.
Everything was perfect few days after I buy it, after that I have problem like you guys, I have logo of ROG and ater that nothing, just black screen). In some time I need to restart it 10-15 times to get in WIN8. I try everything that is inside this thread but no success :/

Maybe you notice that after ~5 restart of your laptop, you have a message something "Do you want to repair your computer?", because windows8 recognize that you can not enter to it. What I did, I go inside this option and I can not remember exactly the name of the option, but try to find something like "Refresh your PC". He will ask you two (2) options more:
1) Do you want to save files and folder from C: drive (win8 withou program but files from lets say Desktop and User will be left), or
2) You don't want to save files (so, Win8 will be refreshed without any programs, files,..from previous windows)

I choose 1st option and I save my files. After that my laptop has been restarted automatically and he do a "Refreshing" something around 20min. Basically he install WIN8 again and install all nessesary drivers (ASUS programs also).

After that my computer work fine. Here past one month and I didn't receive any black screen issue anymore!!!

Off course, after this step you will have two folders on C: drive. "Windows" and "Windows.old". You can find how to delete this folder on YT, or Google as well.

Of course, this mean that ISSUE regarding to this problem is with DRIVERS, and I thing that is Graphic Card drivers. Because now Im updating windows, antivirus, programs, but not nVidia drivers, and everything works perfect. So the thread that one of you type "I try to roll back my graphic drivers and nothing change" is wrong! Something is wrong with drivers obliously.

Also, I said to myself if this problem back again, I will try to remove battery and to remove 16GB of RAM, wait 20sec and back all try to run it. But luckly, I dont need to do that. This thing with "Refreshing PC" works. And be sure to not update nVidia graphic drivers.

Best regards

Hello guys, I just made an account for this specific problem. Here's my black screen problem.

Edit: Asus G73Jh

It started about a month or two ago, I was playing Dark Soul and suddenly my screen went black out of nowhere, didn't moved or hit my laptop. So after restarting it, the screen came back on. So I returned to dark soul then when the resolution changed for the one of the game my screen turned back off again. At that point I uninstalled/reinstalled my driver which seemed to work for awhile then again when I went on DS. It turned off again randomly and it just didn't turned back on at all. So I plugged an external monitor which worked but still a black lcd on the laptop. Then after spending times either in games on on the desktop my laptop screen would turn on and off randomly. Some time longer than others. Not long after, my power supply fried (I'm now on my third PS since I bought my laptop 4 years ago)

I replaced my lcd cable, worked fine for 15 minutes and then it never turned back again. I'm wondering if it could be the LCD that is dead/ dying ? I don't mind buying a new LCD but fear it might not be the problem.

Anyway, I'm aware this problem happened 2 years ago and might still be unsolved but I might get lucky and someone would chime in !

So in resume :

-LCD screen goes black and sometimes turn on again, randomly while the laptop is running.
-An external monitor is working just fine
-Changed the lcd cable and it didn't helped.
-Checked for a faulty ram, they're fine.
-LCD seem highly affected when resolution is changing for games but isn't only affected by that.


Thanks

Hi all,

Since some days I'm also having this problem with my G73JH...
It only occurs when I'm playing a game (So far happened in HoN and WoW).
If I exit the game, my screen works fine again.

I have an extra screen attached (HDMI port) and this one doesn't go black.
I can even play the game on this screen while my main screen (built-in) is black.....

I have tried the following things:
- Lowering down the graphics, didn't solve it.
- Upgrading the drivers, again no...
- Downgrading the drivers, still no...
- Opened the laptop and checked all the connections (warranty is already gone, so why not..), but no...
- Checked heat generation, doesn't overheat, so again no....

Funny fact: (Doesn't work always)
I always work on my laptop with a power-cord and battery attached.
When my screen goes black and I pull out the power-cord, my screen works fine again.
If I put the cord back, it turns black again.
I can't play only on my battery, since it needs to be replaced...

Most of the days, so far, there are no problems, but when they occur, they persist.
It begins with flickering (game to black to game, etc). This will hold on for 5-10 seconds.
If I'm lucky this ends in me seeing the game and if not I'm watching a black screen.
If I wait for like 30-60 seconds there is a chance that the black screen goes away and I can keep playing the game for more then 2 hours with no problems...
And if not, I need to shutdown the game and hope for some luck while I restart the game....

Please asus, come with a solution...

Send it to Asus cause it might not be a VA related problem

Well, just occurred to me that I formatted the laptop not long before that happened which caused the vBios to reset and I was still running Bios 213. Might not be related but in this case nothing can't surprise me anymore.

Anyway, I updated again my vBios, seemed to make a difference with the lcd a couple days later. Been able to run my laptop two days straight without any external monitor and again, the lcd went black.

Seeing how asus gave support to this model doesn't make me want to send it to them. If I'm going to put money on something it will be on another laptop.

Hi guys!

Some of the answers here are off topic for sure. This thread is about when u start the puter u get a black screen ... *nothing* else! No msg at all on the screen, it is just pure BLACK! And the HDMI output is also BLACK. Everything is BLACK! Just pure BLACK like the background of this web page ;)
Period :-)

That's the scenario I'm posting about. Period. :-)

So this is what I found out and its been working for 3 months now ...

The problem is the magnetic electronic contact that is detecting if the lid is closed or not.
And that component is just glued to the puter with some crappy tape that is not holding it if you transport your laptop, or move it a little bit abuse. Yes, belive it or not, ASUS is selling a $2000 laptop that should not be moved ... :mad:

So this component is supposed to be attached horizontal, then gets into vertical mode. Then the magnetic sensor wont work ... and your 17.000 SEK puter becomes a brick stone.

So follow the instructions in this video to open your puter.
http://www.youtube.com/watch?v=Tp90M_N6dzs&feature=youtu.be
There is one really tricky contact to dissemble under the keyboard (5:24 in the U-tube clip), its the upper right. Take care or you wont be able to get it back. If you wont get it back, internal speakers wont work ... so actually no harm done since you probably use headset or external speakers :) ... mine contact is now broken after 3 attempts dissembling and solving the problem :-X ... but ASUS, how the hell can put that crappy contact stuff in a $2000 puter ???
hmmm .. building quali? NO!

The sensor is at the very right down corner of your puter (check at 6:34 in the clip, just to the left of his thumb). Do whatever you need to make it stick in horizontal mode, then problem solved ... at least it was for me :-)

Just about to buy a new puter ... ASUS?
No way after I've seen the building quali inside the puter ... its freaking unbelievable how poor its put together ... Think I go back to the old reliable Thinkpad again!

No guarantee it will help you guys, but it might be worth a try if you got a $2000 brick stone at the moment :-) Calling ASUS is not an option considering what ppl have written in this thread.
And if "calling ASUS" is not an option, who will buy an ASUS again?

Hi guys,

Today I disassembled my Asus G73JH in order to check if the manetic sensor was properly positioned, but I found out that it is not even there !
I sent the notebook to a technical assistance a year ago and I think they lost it :mad:

Does anyone have any idea to fix this problem? Where can I buy a new magnetic sensor?

Thank You All !

Hi All!

Here is finally a solution that works! Forget my earlier post, this is the way to go ... hopefully :-)
https://rog.asus.com/forum/showthread.php?5396-Magnetic-sensor-switch-issue-on-Asus-G53SW-XN1-when-closing-the-lid&p=39530&viewfull=1#post39530

Root cause issue seems to be that ASUS is using an extremely strong magnet for activating the lid closure contact. This leads to that the area around the lid closure contact gets permanently magnetised, leading to that the contact reacts as the lid is always closed, no matter if its open or not in reality :-(

Note that the magnetic contact is placed in different areas depending on your model. To find it, just drag a small iron nut around the square frame on screen. You will notice the magnet in the lid when the nut suddenly is "glued" to the frame.
Then on the corresponding area on the puter, where the lid contact is located, demagnetised it by moving a magnet in circular moves around the area for several minutes (as described in the link above).

BUT ... Problem WILL reoccur if you close your lid without weakening the magnet in the lid, so as it states in the thread, the only long term solution is to replace the lid magnet with a much much weaker magnet.
As a "dirty" fix I have placed an aluminium plate at the frame over the lid magnet. It works ok, but its not perfect. Maybe it gets better in the future when I have demagnetised the lid contact are some more times.

Here is good description how to expose the lid magnet:

At second thought, maybe i just remove the magnet completely, and let the screen be on those few times I close the lid while the puter is running. No magnet sure solves the magnetising issue :-)

mine had black screen on startup but hdmi worked, Fixed it with a hard reboot and setting bios to default. to hard reboot unplug everything and take the battery out, then hold the power button for 30 seconds. then plug in only the power cord and start it up. shut it off after sign in and put everything back . to enter bios hold the escape key and turn on the laptop. use arrow buttons to navigate . select f9 for default settings then save and exit.

Hi everyone, I own a G75VX and currently experiencing the same or similar issues as the rest of you.
One day I left my laptop on to download a game overnight and screen everything works perfectly fine. Next day i woke up and pressed keys on the key board to wake up my computer to sleep but oddly lights were blinking but my screen wont turn on. So I pressed the power button and the laptop turned off. Then i went to press the power button again and laptop ran fine but screen didnt even start or had any reaction. I thought to myself my screen might be dead or gpu has an issue. So i connect my TV to my laptop via HDMI and everything was working and showing. So i thought okay screen died so I ordered a new screen and installed it.... voila screen was turning on everything was working!!
Then on same day i walked away while laptop still on and lid is not closed.. i left it the way it is....i came back and omg... screen is black again and wont turn on!!!
I connected my tv via hdmi cable and was working, i went to the hardware manager and tv was detected as the display but nothing else!! My laptop screen wasnt even detected.
So I disassembled my whole laptop but didnt touch the heatsinks... i reseated the RAM... disconnected the CMOS battery for a bit... checked the lcd cable and seems fine, reconnected it to the motherboard.
I assembled back everything and even did a full power off with battery and power cable not connected then holding down power for 1 minuted and connect cable back on.
Pressed power button and again everything works fine but screen was not turning on or being detected.

Please help what could possibly be wrong?? How can a new screen suddenly works then after doesnt work again?

Looks like my G73JH finally gave up the ghost. It was completely dead. Panel lights would come on, keyboard would light for a second then go out, then nothing. I disassembled, reseated all the memory and cards and replaced the motherboard battery after letting it drain down for a few hours. It now boots to Windows (I can hear the intro music) but the screen is completely dead. Exterior monitor has no display either. I tried baking the card in the oven at 380 for 8 minutes (as seen on YouTube) but still noting. I guess I'm wondering if it's worth the $75 for a new card without a guarantee that it would be the fix. What's the magnet you folks talk about? I looked around while I had it open but didn't see anything. And I ran a paperclip around as well but it didn't get a pull from anything. This thing has kind of been a real POS from the start but I like the form factor and the case is very strong with good hinges.

This happens with my g752vy as well, you have to press the power button to put it so sleep, then again to wake it up. Nothing works properly on these rog laptops. Last time im purchasing asus.
