would not turn on and gave me the ten red blinks.
One more here, I left my panasonic 42" plasma for about two years and a half without use. I remember one of its HDMI ports wasn't working. After all this time I tried using it again and everything worked right off the bat, including the suspected HDMI port! However, the next day, it would not turn on and gave me the ten red blinks.
I tried the power button for 10s thing and it didn't work. I'll try now the different power circuit and if that doesnt work, cleaning (I know all the fans are working though because I checked the first time I turned it on).
I suspect the HDMI port because I tried using it last. Used it fine, turned the TV off, and the next time I tried to turn it on one day after, the problem appeared.
Update
Using a differente power circuit made no difference. And besides lots of years of use (and no use), it was mostly clean inside. I brushed off the few spots with dust but it also didn't make any difference.
Does anyone have another idea? The training and service manuals links don't work anymore. There are no swollen capacitors.
Update
I managed to find the service manual and it says the problem lies with board A. I took it away, cleaned it thoroughly and didn't find any problem that I could see. Still no go.
I almost bought another of these boards online but after more research, it seems the 10 blinks error is a general error that can mean anything but the other specific errors listed on the manual. So, the problem can be on 4 different boards that are linked to it.
After that I don't think it's worth the risk of spending money and not fixing it. I'll probably buy a new TV and think about sending this one to a repair shop.
