Re: Panasonic LED TV model TH-48A402L fault.

1.power supply...

Hello friends,
This is my first post here.

My TV is blinking 20 or 21 times for about 20 minutes before it powers-up.
It will work fine afterwards till I turn it off,than another blinking period starts again.

I do not have a service manual,I wish I could find one.
From what I have seen on the WEB the highest blink code for a Panasonic TV is 14.
Have no clue what is the 20 or 21 code meaning.
Does anyone know?

If there is a service manual for a similar model it may also help.

One thing I have measured...
