Also, when watching broadcast tv or another source (less often) will click and turn itself off and than back on... Will also click like it's been turned on while off sometimes?! I have already replaced the power supply once.... And am using a good surge protector.... The antenna is even ran through it....

After a lot of research, I have been able to locate the part which in my Philips 42PF7220A/37 Plasma TV appears to be the problem. I found out that heating and cooling certain parts of the board(s) allowed me to get beyond the 5 flashes error message and power up the TV. Through a process of elimination, I narrowed it down to the SSB Tuner board 3104-313-60376, This board is located behind the board covered with the shield. The specific component in question is the one I have circled in red on the attached photo. It is a crystal Xtal 27 mHZ 18Pf PART# 2422-543-01397. When I spray this component with cold air (freeeze) for a couple of seconds and then plug the power back in the TV will go through it's initialization cycle and turn on. It may turn off automatically, in which case, you just power it back on either manually or with the remote. It has now been 7 days, and it hasn't failed since. I have NOT replaced the part, if it fails again, that will be my next step. The part is about $ 10.00. The entire card can be purchased for about $ 100.-
I am reluctant to do anything further, because I'm not positive that the component is the problem or possibly the input to it. What I do understand is that a crystal can be excited (turned on) by either heat or cold. Perhaps it was stuck and spraying it with cold and heat released it. In any event, the TV is working for now. Hopefully it will stay this way.
If anyone can shed some light on why this may have happened, I would appreciate it.

Go buy a CRT television for $200 and chunk that HD TV. All of them are made in China with the same poor quality. Why seemingly smart Americans would pay good money for such junk is beyond me. The LCDs are a cash cow for the monitor and TV industry as they are well aware the inverter boards will fail within 3 years time. The old CRT tvs will work for the next 15 - 20 years without failure. Get you a good ole 36 in sony black stripe tube and kiss the LCD crowd good by.

I had a Similar problem where I would turn the tv on and the green light would come on and then the red would follow and blink 7 times. I tried unplugging it and then then replugging it back and it would still do the same. What I did last night was that I unplugged it and then replugged it back, when I saw the green light, I would unplug it again, till the light went out and replugged it, I did that 3 times in a row, and waiting and it came back on. Hope that works. I still don't know what caused the problem to begin with..

I had the same problem with my 1 year old 26" TV. I called Magnavox customer service, and they had me upload a new software driver to the TV - which didn't solve the problem. Then they suggested that I call the local Authorized Service Center - and they estimated that it would cost $200+ to fix the problem. But then I found the "remove the back solution" listed here - and it worked!
Thanks, you saved me at least $200.

OK this is a classic switchmode power supply problem There is a fault either IN the SMPSU, OR in another part of the set, usually a short circuit. The PS, is "Shutting Down" for safety reasons, so as to avoid a possible fire, explosion etc. You really need to have this looked at by a qualified person. before you get any work done, always ensure you get a firm "Quote" before proceeding. This is very common.
