G73JH Black screen :(

[Yemon]

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.

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.
