I know that Panasonic (until a few years ago) provided the replacement of this card in exchange, which means that it was easily recovered, in my opinion.
The cost was 270€ excluding VAT...Leave a comment:

Hi Erik,
I've been going to this forum for years but haven't signed up yet.
I read your message and decided to answer you.
Meanwhile let me introduce myself, I'm an electronic technician with almost 40 years of experience in the repair and design of electronic equipment, I write and live in Italy so we are not too far away!
What you are asking is not simple, the Panasonic plasma boards you mentioned are 10 years old and spare parts are not easy to find, moreover they are very complex boards......Leave a comment:
