I had panasonic Tv TC-20L3T , it have no picture & no sound, but when it is On there is a shrrrrr..... sound inside the Tv. There is power and power led is normal. But no picture and no sound just shrrr.. sound inside. I checked the horizontal transistor
All the voltage in the power suply are ok? You trouble sounds like the power supply capacitors does not work.
