Re: Panasonic tv 27"

I not familiar with this model but, If the video select button is below the screen. I would suspect "windex damage"! Cleaning screen by spraying directly on crt causes this is some sets. The button gets corroded or part of this circuit. If this is the case, replace/ inspect/clean around switches.
Protection diode(s),capacitor across switch, faulty switch or bad processor input are other causes.

No video/audio when TV is turned on..

This set is popular for the main voltage regulator to be bad. If you have a meter check the input voltage . it should be between 135 to 159 vdc. Now pin 4 should be aroud 125 to 130 when you switch the set on. Hope this helps Good Luck
