Question about Toshiba 42HP66 42 in. LCD Television

Open Question

Only half of the screen works

Turned off last night and it was fine, This moring turned on and the right side is black seperated by a line to the left side which is fine. Called where we bought the TV and said to unplug it and it would reset. Didn't work and I am getting pissed as the TV just went over a year old and has not been used much.

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?

No picture, has sound. Black screen with green lines.

Probably a power supply issue in a 7-year-old TV

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)

Last night the screen started going dark, then went out, black

If still under warranty, I would suggest going that way as this is a bad matrix driver....
