TX29GF10
Panasonic TX29GF10 29" won't start. I can hear a clicking sound when I try to switch it on by remote or otherwise.
First try to find out if you've got the correct voltage's on the secundaire site of the power suply. Sometimes e.g. there is a short-circuit in the deflection circuit, and the power suply goes into a "safe-mode". Also check the status of the "stand by"-led.
