I had the same problem....moved to a new home, and the TV power button would turn green, then red, then off. It 'fixed' itself when I pushed the "menu" button in on top of the TV.

I'm having similar issues and was wondering if you had any success changing out the logic board. We replaced the small signal board already, but no luck.

Five blinks is a severe hardware failure supplys not working. Viper is down. You have atleast a bad power supply board could have taken out your sustain boards. If you are good with a meter you can measure voltages and see if just your power supply is dead. If you have never handled a multimeter you will need a tech and a power supply is not cheap..Power supply is about a 600 dollar board.

    The only other thing that could really cause what you are talking about is the logic board. If you are looking at the tv it is up under the main board on the bottom middle. This board could be causing shutdown and is connected to Y sustain which is also connected to the powersupply board. This board taking a dive can take the whole tv down. Not as bad on price around 300 dollars it is subbing to part number 996500038481 if you can swap that out like you did the power supply though you might save some headaches.

Turning on my phillips tv the power button is blinking red


Plasma? Your power supply has bad capacitors. 3300uf most likely. This is a common problem on some Philips plasma TVs. Power board is located top center of the TV with the rear access panel removed. look toward the lower left portion of the board. If you notice any capacitors (they look like little plastic wrapped cans) with swollen tops or leaking dark fluid from the top of them, replace them. Myself, I always step up the voltage rating... ex: 3300uf, 10v -> 3300uf, 16v.

Blinking red led light when I plug in the tv then it turns right


Phillips purchases the main circuit board from Samsung, and it has a problem with capacitors failing. The failed capacitors can be easily identified as the top will no longer be flat, but will have bulged up.
If you have a local TV repair shop they can help you.
