No Display on Z71v

perhaps this is a dumb question, but have you tried Fn + F7 and Fn + F8 to make sure your LCD is selected for input? Also, did you check the LCD connector?

I'm having a similar issue with my z71v. In the middle of WOW my screen started acting funny the it was done. I had the same thing happen while it was still under warranty and it was the 6600 card. Now, for the life of me I can't find that card on my own to purchase. estore.asus.com does not sell it any more, but they used to. If you can find a replacement card let me know. I'll post a source for it if I ever find one. Otherwise I'm gonna have to sell mine for parts.

well, they don't sell the 128 MB version, but if you're okay with a performance hit, they do sell the 64 MB version: http://estore.asus.com/shop/item.asp...3467&catid=357

Yeah. I can't take to hit at this point. This was my only box I could play WOW on. I'm going to sell her off for parts and build a desktop rig for gaming. She was a great notebook while she lasted.

You might be able to get one from a reseller with extras.

If your sure your computer is actually starting and loading windows, i doubt it's the video card. The laptop wouldn't start at all if it was, which was my case. The power button lit up, but it never got anywhere.

Replaced my video card and it worked.

Reneki when you had the problem did your fans come on full blast?

Hey mac_bug, my fans did come on full blast, but after i removed a stick of ram. Otherwise, it was still black, nothing on the screen, no beeps, and no signs of it loading windows. But you heard the fans, more so when i removed some ram.

If you dont get a WHITE screen, it means your graphic card is still working somehow. White screen means that there is 0 signal.

Check/Jiggle point where the two cables from the monitor connect to your motherboard and VGA card. (there are 4 cables coming from the LCD panel, 2 thin round wires for the wireless antenna, 1 video cable and 1 power cable).


Try to plug another monitor to your laptop on the VGA port and do FN-F8 during boot. Hopefully you'll see things appear on the external monitor. If not, then your mobo might be dead. Not the graphic card.

To be sure the mobo isn't really dead, let your computer boot up. Look at the LED light for the hard drive, if it flashes randomly, it means your hard drive is being read, meaning something is loading, meaning your motherboard is fine. The HDD LED is left the wireless LED and right of the NUMLOCK LED. Or simply, the 3rd LED starting from the power button, going left.



Finally, I'd just take apart all that I can and piece if back together one by one to see where things fail. The Z71V is a very sturdy laptop, it can take quite an abuse without breaking, so don't be shy. My graphics card have been so abused that the PCB board is not flat It is actually caved in and it still works 100% )

Whoa man... same thing happened to me last tuesday... screen completely blank and it's not the backlight as when it's turned off you can still see something, I've been looking for the 128mb version of the card but no luck, the 64mb version is available but i don't want it since it doesn't run Aero (Vista) @ 1680x1050 which I had been enjoying for the last couple of months.

My computer also will just do nothing it i just tun it on... but if iuse te cd player feature (inserting an audio cd and letting it play) and then turn it on it goes all the way into windows... but i can't still see anything, i've also plugged another monitor and it sill doen't work.

Also took the laptop in for diagnostics at a local shop that specializes in notebookas and they too said it was the graphics card but that it was very hard to get....

We'll keep in touch if anything surfaces ok?

the same thing happened to my z71v last month, i can hear the windows sound when it starts up but screen stays black even when i plug it to a monitor, did anyone have any luck finding the 6600@?

I posted this on another thread just before about my personal experience and how I fixed it for me.

When my GFX card crashed with garbled video artifacts while playing a video game, I did this to fix it.

- I had to plug in a monitor on the external VGA port, and activate the double display by pressing FN + F8.

My external monitor would show garbled video stuff [ main symptom of bad video memory ]. I'd then get into windows. The gfx card would be detected as Generic VGA, so i'd be in low resolution. I'd then play some videos for a few minutes and somehow, that would slowly "clear out" my video memory.

After, I'd reboot the laptop and NOW my main LCD would be activated and my GFX card detected as Geforce 6600 GO.



So, i dont know what to tell you. Your GFX card might be salvageable like mine. However, it's probably not going to be exactly what I did with mine.


Also, I had problems with the gfx BEFORE the garbled graphics which also resulted in blank black screen upon boot up.

- If my GPU is cold [ laptop was turned off for hours ], so I need to turn on the laptop, let it run with a blank screen, then turn off and reboot.
- If the GPU Heatsink screws are too tight [ specifically the right side in my case ]
