    Right side of the screen is fine. The left side is black with approximately 30 random but stationary vertical Red, Green and Blue lines scattered across the black side.


    I disconnected all input devices, turned off and restarted the TV. No help.

Any advice on what board I should replace if the left half of the screen is no good, just showing white and black vertical bars? Right half is fine. Is the panel kaput?

Dell Latitude D505 half of screen is black with colored vertical lines.


Sounds like you have a section of dead pixels. This can happen if the laptop has been dropped a lot or stepped on or some type of impact on the laptop. This is a hardware issue. You will need to have the screen replaced. In my opinion, by the age of the laptop, its better off getting a new one.

LG 37LE5300 HAS HALF BLACK SCREEN


THIS set uses 2 boards inside--one drives the left and the other the right side of the screen.

You have to id which is which (GOOGLE?) AND replace it-every brand has different names for these but it sounds like your problem

Some research (you or me) should give a board breakdown for this model---not looking for main or power board but another like sustain etc. and there will be 2 listed (for right and the left sides)

42" LCD tv shows picture on only half of the screen,other half dark!


The T-Con board (otherwise known as LVDS) connects to two seperste parts of the LCD panel. If you do have half a picture (left or right) replacing the T-Con board should resolve this issue. Open your TV, find the part number and search on eBay or at sites like www.flattvparts.co.uk where you can search by TV model number.
