I have yellow vertical lines on my display. It seems to be the video card. Where can I find a used one?

More than likely it's the lcd screen and will have to be replaced. I could be the video card, but most likely the lcd screen especially when you can put pressure on the screen and cause changes. To isolate the problem try connecting another monitor to the computer. Borrow a monitor from a neighbor, friend, relative or co-worker and connect it to the laptop. If the Borrowed monitor displays ok, then the problem is with your lcd screen and the video card is ok. If the Borrowed monitor displays the same as your lcd screen then the problem is with your video card inside the computer.

Plug in an external monitor and see if the display shows up on it. It can be any kind of monitor even the old big fat crt monitors as long as it has a vga cable to connect to your computer's vga port. If so that proves your video card is ok. The video will show on most systems when you reboot without you having to do anything. Some systems will require you to hit the FN (Function key) + F1 thru F12. Hold down the FN key then hit the correct key for displaying on the monitor (F1 thru F12). The correct key will normally have CRT/LCD on it or it will have the icon of a display.

Once you narrow it down to the lcd screen as being the problem you might try taking the lcd screen apart to reseat the lcd cable on the back at the top of the lcd. Just unplug it and plug it back into the connector. You can also try doing the same where the lcd cable plugs into the motherboard. Just pull it out and put it back.

looks like that your vid.card has a compatibility issue.
but since that you've tested this w/other computers and still the same?but your computer works on other vid.cards?
that means,there's a big chance that your vid.card is already busted.

Hi,
This is definitely a display issue ,going black could be the inverter or cable, as you are getting vertical line, it seems you need to change the display.It seems the heat produced by the video card in your system is too high if the cooling is not enough it might give you this problem due to over heating. Maximum GPU Temperature (in C) 105 C for nvida GEFORCE GT 120M.

The screen resolution for your laptop is WXGA++(1600 x 900) which is 17",for this kind of display I would say display nothing less than 1920x1080 or 1920x1200 is high defination (HD) display.

The GRAPHICS card you have in the system it has

• Maximum Digital Resolution 2560x1600
• Maximum VGA Resolution 2048x1536
• Maximum GPU Temperature (in C) 105 C
• Maximum Graphics Card Power (W) 50 W
  

Try to decrease the hardware acceleration of the video card and check how it works.Other wise replace the display.

Try to check first if the video card cause these lines..
Turn off your computer, replace the video card and check if the lines still display..

If you still see lines, check the cable connected on your monitor to the video card, see if its properly secure and not loose.

If you still see it... then my suggestion is you bring your monitor to a credible technician..see also if your monitor still have its warranty

There could be 3 possible reasons for a vertical lines

1. Driver for graphics card needs to be updated
2. Grpahics card faulty
3. LCD problem

try connecting an external monitor and see if the display is also vertical on the monitor, if yes the problem is graphics card, if no, the problem is the LCD. Hope this helps

there is already a problem with the video card.. for most laptop, they have built in video cards.. so you need to have your laptop checked by a computer technician.. or it would be best to bring it to the manufacturer, so they can install the right drivers for the video card after being fixed..

Have you tried hooking it up to an external monitor?
This would ensure that it's the screen and not the video card..
If you do that and you receive a good picture then it could be something as simple as a loose video cable. Or it could also mean something like a bad video card or the expensive one, a bad screen.

I would try to update the drivers for the display adapters, to do this, go to start>control panel>system>hardware(tab)>device manager>display adapters and select the appropriate adapter and double click it and go to the driver tab and update driver. If this doesn't work, go to device manager and try updating the drivers to the Monitors.....same thing.

try replacing the video card first.

Alright, I do believe i have a solution. But i need to know the brand of TV you own, how old it is, and If your using an adapter, or the regular "Yellow, Red and White" cords.
