Question about Philips 50PFP5332D 50 in. Plasma Television
My Philips 42PF9630A LCD TV runs about 5 - 10 mins. before shutting down. Clicking noises come from the box and the green LED (normal operation) is replaced by a red blinking LED - blinks 7 times before pausing and starting over again. Sometimes there is static before shut down. Sometimes the display goes wonky before shut down. I did upgrade the machine to the latest firmware - no change. No SW or HW events logged or errors logged in the service menu. (My house did experience a couple of 'brown outs' in the last week.)
Those blinks [flashes] are fault indication (Error Codes). From the number of blinks occur at one time switch ON, you can get an idea about the faulty circuit section inside it. This will make repair easy. These are called blinking codes. Make sure about the exact number of blinking of the standby/power LED, by switching On & OFF the set, for at least two times. Count it carefully. If you wish to get some details, check the site linked here. It has details about blinking codes, and fault locating procedure, to many popular brand TVs and other devices.
If blinks continue without any pause, the main board is faulty.
Search the site by type in the "brand name" to your device, in the "Search box at the top right of the display window of the Homepage" to get gathered related posts.
Counting of number of blinks to Philips TVs is entirely different to that of other brand TVs. It is not a direct count procedure. The site have details about how to count the number of LED blinks [Fault Codes] to Philips brand TVs are given; along with details of the faulty circuit location.

I had the Same issue. on a 50PF9431D/37 set. Many Plasma Set's use a LJ44-00118A PS-505-PH Power supply from Samsung. Known to have this common problem. If you can, or have a friend that can Solder components?. Unplug your set remove the back panel & locate your power supply. It will be the PCB in the center of the set just above the Video/Audio connections. http://www.shopjimmy.com/power-supply-unit-lj44-00118a-from-philips-50mf231d-40.htm. Is a Link to a photo of the PCB. Make a note of the locations of all cable connections then unplug them all. Un-install PCB, Check all Fuse first. I believe their is 5 or 6 of them on the PCB. Then replace the two 3300uf 10v 105C Radial capacitors at C8060 & C8059. Look to see if the Caps are deformed and or split at the top. The location of the caps are in the Lower bottom edge of the PCB. A local shop may Carrie them if not, digi-key has them. Part # http://search.digikey.com/scripts/DkSearch/dksus.dll?Detail&name=493-1754-ND. Total cost was $7 with S/H.

Normally, this happens when the TV detects a bad circuit board and goes into " Protection Mode ". The blinking red light should be a error trouble code. I don't have the Service Manual on hand for your model number to tell you what the code means.
Most likely the TV has a power supply related problem. It's possible that it maybe a bad capacitor or transformer on the power supply board. But, I can't say it's 100% the problem because I can't actually look at the tv over the internet. I can only make guesses with the symptoms.
You have a few choices:
1. You can try leaving the TV unplugged for 30 - 45 minutes so the TV can discharge and reset itself.
2. If by chance the TV is still under warranty, go that route.
3. If you have some electronic experience, if you can find and purchase a Service Manual over the internet; It will help you diagnose the source of the problem and fix it by soldering in the new part. The Service Manual will give you red light blinking codes, circuit diagrams, test points, and part# lists.Usually, cost under $20. And most cases the new part cost less than $15.
4. Pay a TV shop to do the repairs. It maybe costly, but get an estimate of how much they will charge. That way you can decide if it worth repairing or replacing the whole TV.
I hope I shed some light on the subject for you.

7 blinks indicates a bad buffer board, usually I replaced the Y board and the buffer/s about $500-600 in parts. but before you buy anything open the set and look at the power supply if you see two capacitors that look swollen , bulging on top they need to be changed and may solve the issue. the power supply is middle top . If you are not wanting to repair it yourself then know that you do have some circuit board repairs needed.
