My Goodmans widescreen TV is about 5 years old. A few minutes after switching it on there is a crackling sound for a while and then the picture goes off.
Any ideas what the problem may be?
I have had the back off and there is nothing obviously loose. The only difference between it working and the problem is that it was moved to the garage for a few days (April 2004) while the room was decorated.

The TV returns to standby ?

Try blowing out dust from over the circuit boards.
Also carefully, and just one at a time, remove each plug & socket connector inside the set and blow the dust out.

Going to standby can be caused by one of the voltage regulators goping faulty or perpahs the line output transformer.
