I have progressively more verticle lines appearing on the display. Is there a way to coorect this without replacing the entire display?

First off there isn't a timing board in a plasma TV. I would guess you have a bad y-sus board.

Unfortunately, if this situation occurs in both the internal monitor and the external one, this is almost certainly a burned-out video card that is no longer able to output correctly. Without the hard drive the BIOS will still engage and try to boot, thus engaging the video card - but without memory, the PC will not POST, resulting in the black screen you're seeing.

This laptop will almost certainly either need to have a new video card installed or be replaced entirely.

Good luck, and hope this is helpful!

Sorry, no help. There are no spare parts for these scanners.

Failing Display Panel Circuit Board... THis Means You Will Need A Screen Replacement..

Open this link and make it full-screen. Watch the screen for 20 seconds or so to see if the line of lit (white) pixels remain.

If this line remains during this, and even when the the computer is first starting up, it is most likely a row of "lit" pixels caused by a faulty connection or circuit inside the display.

While you can sometimes rub the area of the screen near a single lit pixel, an entire line of them usually denotes a more complex problem that can only be fixed by having parts replaced by a technician

Note: Be sure all of your cable connections are securely fitted, and that the line is there no matter what is displayed on the display (especially at the boot screen before Windows loads).

Hardware failure, nothing much can be done, just replace the scanner.

Does the picture look 3-D at any time?

Honestly you have a big problem because the driver IC & Tape Carrier Package inside controller board at vertical area are damage or itself defective could cause you have 2 inches line appear in your display. The best solutions for this replace lcd panel to fix vertical line.

Hi...there,

Well... I hate to say, but you got a damaged panel. Thinking of replaced the panel... you can forget it.
Get a new one...it's will saved you the headached and $$$... Have a nice day!

I am woundering if the repair folks did the proper job and used the right IC's as alot of NON authorized shops will use the cheap aftermarket repalcement ICs and not even use any new heat sink compound. 4 repairs in 5 years is very excessive! I would not have called the same shop(s) to do the repairs. Put on the test scren on the TV set and see if the convergence is off. If it is make the shop replace them again for free or ask for your money back. Man what a rippoff that is. Good Luck and keep us informed of your progress with the shop and the repair.
