Same problem here. 5 blinks is video related. I've been told to clean the screen by the lamp, as they could be clogged and causing it to over heat. Going to give thet a try first. I'll post what happens...

It's not to complicated, in the newer TVs as well as other things, when you first turn them on the diagnostic circuits kick in [that the first relay you hear click] it sends a signal (low voltage) to all the circuits to check them and make sure there are no problems. If it gets the proper returns from each circuit it kicks out and the full power relay kicks in and powers your set up. This is done to protect others circuits that might be effected by a flaw in a different circuit. What started as a small flaw in a component has gotten worse with use which is normal. Your set is kicking the diagnostic circuits and they are detecting the problem and shutting it down. You have problems with your power board, if the diagnostics circuits were not in place and full power hit the set the power board could possibly put triple or more voltage to some section of another board, thus burning it out also. That's why they started using the diagnostic circuits on TVs, Computers have had them for years. Late model car - etc. I would take the power board out of it and go to shop Jimmy's and enter the part # which will be on the board and order me another one and pop it in and kick back and watch TV again. I don't know what a power board would cost for it but "shopjimmy's" carries high quality boards at a reasonable price. I do caution you on buying a refurbished board, they are tempting but I have never and I mean never seen one hold up very long. As a matter of fact I will not put one into a TV or anything else for that matter. So there is light at the end of the tunnel and it's not the train this time! I only work on the kind of TV that plug into the wall or run on batteries, therefore, I've seen a bunch of them in14 years. Don't worry about getting the wires mixed up because one thing about TVs is a harness or plug will only fit one place and that is where it belogs you can't cross them up.
