Panasonic TC-P50G10 9 blink repair?

[spoony1]

Well the sets been sitting for almost 3 years and I thought it was high time I got to fixing it or bought a replacement. Went and looked at the newest offerings and I don't get it. I was not impressed so I better fix this one!

Was pretty disappointed with this set only lasting 5 years but the picture quality was always great. 3 years ago it started not coming on unless I held the power/on button down for extended lengths of times. It had to be held down longer and more frequently as time went on. I was originally getting either 2 or 3 blinks when the set wouldn't come on?

When it finally stopped completely it went to 9 blinks and that's where it stands today.

Pulled the back off and noticed a couple caps on the power supply bulging slightly so I thought I would start there. My question right now is what are the best caps to use in a TVs power supply?

I have worked on a lot of vintage audio, amps, test equipment, turntables and the like but in all this time I have never worked on a TV so I am asking for some suggestions from the authorities.

Thanks and awesome forum,

S

I dunno but I think it'll be an A- board issue

Probably right on about that. I believe 9 blinks would point to the A/Main board.

I looked the A-board, as well as the rest of the TV, over very closely for any blown parts or other obvious signs of damage but couldn't see anything. I just decided to start at what looked most obvious to me and that I could repair myself.

When this first happened there were a few people who sold the A-board but I cant find anyone now?

Thanks,

Hi tiku,

So I replaced the caps and still had my problem, I found a used main board to sub in and the blinks went from 9 to 5 still not coming on. I then very gentle, methodically disconnected the various board connections one at a time, cleaned, cleaned the socket/attachment, reconnected and voilà the set is up and running.

I don't know how many times I have simply cleaned connections and got something to work.

All the best on the Panasonic. I know why I was trying to fix it, probably the same reason you are, it has a great picture,
