Techwood TWP4205. I have no picture via sky or dvd. It started by the picture going black/white/greyish then the picture went altogether it did come back on if we turned the tv off. Havent tried it for a few days. Have been told that it is the media/tuner box that needs replacing.

Too late now but I hope you had it serviced while it was still on parts warranty. With a couple of exceptions, service on those is by major pcb replacement.

Hi,
Do one thing press the SCREEN MODE button on the remote repeatedly and check is there is any difference in the screen. If there is no difference then yu tv Have problem wit the T Con board, T con board is on which drives pixels the lcd screen. You can find the T con board of your tv in the following link.
Normally you can find the T con board inside the tv at the bottom center covered by metal cover or aluminum foil. Replacing this board will solve the problem.
