I can tell you what is the caused of the 10 flashes of the led light (Panasonic Plasma TV TH-50PZ80U). I'm online at pay question click it here if you want to know it and I will help you to fix it yourself.
Thanks for the quick answer. I purchased the set in 2005 and it lives outside under an overhang on my patio in humid South Florida.
Unfortunately, I couldnt count the red flashes before it went completely dead. Think it was 4or 5. This would correspond with a possible fuse failure on the Power supply. I bought the online service manual, I just wish I knew what to do with it!! The fuses both seem to check out ok on a continuity check. any ideas?
Most of the time when this happens it is the ysus board, that noise you heard was a capacitor popping. Another board runs about $175 and thats if you do it your self. A shop will most likely charge around 500-600, hope this helps, you could also try contacting panasonic and trying to get past the tech and onto casemanagement where you might get somewhere with an out of warranty fix.
Can you count how many times it flashes ? It might flash like 6 times and pause for 2 sec and flash 6 times again. THen call a service comany and tell them this info and they might tell you what part inside is bad. They are not telling you this for you to replace but they might say something like oh 6 flashes is a Y board and we will have to order it. Hope this helps
