Vizio P50HDTV Display Problems - Colored Vertical Lines .

most likely a damaged sensor. How about the pictures? Do they show these lines on them too?

What is the brand and model number (not indicated here) so I may try to give you an informed answer.

You have a vertical problem. You may need to resolder the vertical IC, and check each cpacitor that is near the vertical IC. Your TV will be restored to full screen!

If you can see the vertical lines during POST, try to check the vertical lines in BIOS. If the vertical lines are there in BIOS, the only thing you can do is to replace your LCD screen.

My 42" Samsung Plasma HDTV HP-R4252 has a 2" vertical strip of green pixels down the right side of the screen.

My 3 year warranty with Circuit City expires in Nov 2008.. so I hope I'm covered.. can't call until the morning.

Samsung said it might be a logic board problem.. but they want almost $2000 to fix. I might as well buy another TV if Circuit City can't fix it.

If your seeing vertical line across the screen you need to check the components in the vertical stage as well as the vertical IC could be bad, or the yoke could open.
Also check if any voltage reaching the vertical stage.

Good luck.

Was this help full.

If the Tv turns on (power supply is ok), screen lights up (inverters are ok) but don't get a blue screen, menu options, source options, or audio, it's most likely the main board (aka Motherboard) is faulty. If a DVD player is hooked upto the TV, check whether you can get audio from that (change the source using remote), in such a case it could be a problem with LCD Interface board. My $3 is on faulty Main board.
