PanasonicTC-20L3TI 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 transistorAll the voltage in the power suply are ok? You trouble sounds like the power supply capacitors does not work.23-06-05
PanasonicTC-20P1I have this panasonic tv which is stuck in standby...the HOT and the power regulator is still in good condition... the remote still works... when you press the power button, you'll hear a click from the relay but no oscillation on the flyback... No High vim not so familiar witd this model but try thisif there is an error corrector in the power supply circuit check for risistor w/c is off value or try to checked all the risistor and signal doide on the power supply and what no. is the regulator to be precise so i can pin point the problem23-06-05

PanasonicTC-29GH12HAnother more than 10 year old 29" TV. The picture is getting REDdish. Even for white color. Try to lower the saturation but sure it is not a color setting problem. On the crt board you have 3 drives. Red, green, and blue. Check the voltage on each transistor. You might have an open b+ to a transistor or a bad driver.26-09-05

PanasonicTC1S3RTo enter service modeSelect programme 60,( It helps if you tune in to a channel first) & set sharpness to MIN. Press Off Timer button on R/C & at same time press /(down) button on set, this will place TV into service mode. Press the / / / buttons to step up / down through the functions. Press the + / - buttons to alter the function values. Press the store button after each adjustment has been made to the required values. To Exit service mode press the normalisation button. 14-09-04
