I have a 2009 Panasonic TC-P65S1.
I put it out to pasture about 9 months ago out of frustration, and finally got the gumption to try and figure out what was wrong with it again tonight. I've been researching for the past few hours.
Previously, the TV would shut down and the LED would blink 8 times. This would occur after the TV was on and displaying an image for between 5 mins and 2 hours. Tonight I thought that I would try to duplicate the problem so that I would have more information before posting, so I removed the rear panel to have a quick look around and then plugged it in and fired it up. Now I am getting an immediate shut down and the LED is blinking 9 times.
I guess that I may have disturbed something while removing the rear panel. The only other possible issues that are immediately obvious to me is that the three large 220v, 1200uf caps on the power supply board appear to be slightly swollen on top. This is the first time that I have removed the rear panel.
Does anyone have any possible suggestions? Do you think that the three bulging (failing) caps could be causing both of my error codes?
