The picture shouldbe free of vertical or horizontal lines.

A single set of horizontal lines could indicate damage, a graphics system failure, or loose internal video cables. Broken signals from cables or graphics hardware creates impurities in reproducing an image on an LCD screen, conditions that often manifest in the form of vertical or horizontal lines of color.

SOURCE: Philips LCD model 26TA1000, vertical lines and blank white screen with no picture
it would be easier to find it stripped from a damaged set on ebay.
I see several there but need the part number to search
of course you may purchase that and find it to be the lcd driver.hopefully not.

Hi,
Hi,
The most common cause for the loss of picture is a bad Horizontal Output Transistor
(HOT). but I would suggest you get a detailed
estimate. I think that this would cost you about $60.
The horizontal lines means the vertical amplifier or deflection system
has failed. There are over 100 components in this section and any one
of them, or most of them can be at fault. However, the most common
failure is the VOT or vertical output transistor (which is often buried
inside a chip).
The repair will cost around $250 plus or minus.
FEW TROUBLESHOOTING STEPS YOU CAN TRY:
ONE: Do a hard reset (just to make sure there is nothing in the coding
that is fowling things up). Unplug the power cord; leave it disconnected
for 4 hours. That will restore everything to factory defaults when you
power it back up.
TWO: Do the "whacking test" by banging your fist on a few strategic
places to see if there are any cold solder joints or loose wires acting
up inside the set.
If the above steps don't solve ur problem then I suggest you to go for a repair..
Goodluck..

If the screen works for a short while and then completely fails once the TV warms up you have a problem with the main unit video board or the LCD control logic board. Most often if the picture cuts out but audio continues to work the logic board is over heating and should be replaced. However if the picture cuts out and audio shuts off as well then its your video input board.
