I have a plasma TV that does not turn on. I first had an issue with attempting to power it on a couple of months ago. It would make clicking noises, but not turn on. Usually this model has a blue light indicating power...it would instead flash a red light a few times. I then unplugged it for a few seconds and it would turn on. This cartoon went on at least a dozen times. Now it doesn't power on at all. Has anyone got advise on how to resolve this issue. I am mechanically inclined, but I am a novice in electronic hardware. Any and all help is appreciated!

Assuming you have no warranty to void, go ahead and carefully open it up to the point where you can see the power supply board. Check the caps to make sure none are blown. While you're in there, look for burnt or blown components. If you find something, report back with pics so our more technical members can get you pointed in the right direction.Ludicrous gibs!

Sometimes the flashing indicator lights will flash a code. These codes are found in the service manuals. You should be able to find the service manual for that unit here:

This took a little detective work, but you have the EJ3.0U PA chassis. Google that and your first hit will take you to elektrotanya.com where you can download the service manual.
Dgtech beat me to it!!!

Re: 50" Philips 50PFP5332D/37 (No Power)
More information would be helpful. When the power button is pressed, what happens? Nothing, relay clicks?
The first thing to check would be the two fuses in the lower right corner of the power supply. You might get lucky and find one of them blown. No, it's not OK to replace it with a piece of wire.
Assuming the fuses are good, the next step is to examine the connectors on the left side and bottom. IIRC, these have labels indicating the voltage they supply. The one you are looking for one may be numbered 1M03 or 1M46, and have a pin labeled +5V2stby or something similar. Now put the power supply back into the TV and hook up all the cables. plug in the power cord and check the voltage on the pin you identified above. Measure from the pin to chassis ground (one of the power supply mounting screws is fine). It should read about 5.2 volts.

The voltmeter that PlainBill recommended is discussed here, but the ebay link is dead/expired ...

I bought a used Meterman 15XP off ebay and it works great. Just don't buy any variation of the cheap DT830B under $5 variation. It is total crap. I know from first hand experience.
There is a Meterman 30XR (new) on ebay selling for $12USD + shipping. I have never dealt with the seller, but it looks like a good price for a "name" brand meter.

Re: 50" Philips 50PFP5332D/37 (No Power)
I am trying to repair this model for a friend. I notice that my power supply's picture is rather different from the ones posted. So, here is another version of the power supply board....
I guess I should note that the board version number is : PS-507-PHN
I purchased a rebuilt on eBay. Looking at it, I get the impression that blown capacitors is a common problem. My friend felt happier with the rebuilt, than my repair of the board. I assume that my replacing the obviously 'pregnant caps' would have done just as well... Anyone else have an opinion?
Onward....
