Hi, Channel 3 or 4 might work for older TVs. Most new HDTV's have a mode setting in the menu. (Video 1 or 2 or 3) or (Component 1 or 2). On your remote you may have DVD button. Try all these suggestions, 1 of these will work. You can play with the remote too. Good luck.

check power at the socket, if there is take it to an engineer. Don't try and fix it yourself. This page if full of tales of people who change boards and never end up with a working set. The course is 2 years, the test equipment costs thousands.

The power supply will shut down if there is an over voltage/over current situation in a secondary supply.
Check the secondary side of the power supply.
