I have the same problem and have traced it down to a potential power supply issue.  I bought mine at Best Buy in '06 and was told today that they will test the power supply for free.  It may range from $50.00 to $100.00 depending on where you can get it.  This does not include labor for those not qualified to work with electronics.  Hope this helps you.

www.cfusion.com has the spare parts for that tv. it sounds like it is the mainboard. shouldn't be more than 150-200 to replace.

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.
