Tv will not turn on and green light blinks 3 times constantly


Your main power board located in the center where your power cord will plug into is going bad, actually it's just a relay. I have the same problem, tv works for hours til relay overheats, then tv shuts off and tries to restart, hence the clicking and the 3 green flashes, mine will actually restart after 15-30 minutes. search online for the board, ranges anywhere from 150-280. I haven't found anyone to sell just the relay. I am trying tv with rear panel removed and cover removed from relay to see if relay will not malfunction? Board is a simple plug and play, just remember to have the tv unplugged.... you can actually remove the rear panel while on it's stand, just don't remove the screws holding the base onto the tv.
Good luck!

Turn's on but i don't get any feed back on tv. tried using 5 plug rca and 3 plug rca tv doesn't have hdmi input


Was it Hooked up to HDMI before you tried those cables? You can reset the video settings of the PS3 by holding your finger on the on switch when you turn it on. Leave it on there till you hear it beep a couple times then shut down. Hope this helps. Good Luck
