I would not diagnose over a forum. I get in the shop with service manuals and gear. What if it's some other failure like the backlight system?

I have UN55EH6070F. It will no longer power on. It's about 2.5 years old. One day it cut out a hand full of times and just came back on by itself. The next day it wouldn't turn on at all. After googling a bunch I read about the capacitors problems on the power board so I order a new one on ebay and swapped out the part. Unfortunately that does seem to have been the problem. I guess it's possible that the replacement part was bad to but the capacitors seem to look fine, no bulging or black marks on the top. Not ready to give up yet. Any suggestions on what parts to throw at it next would be greatly appreciated. When I hit the power button the red light flashes 8 times then a short pause followed by 5 more flashes, if that tells you anything? Thanks for your time. -Dan Anderson
