You have a bad main board most likely. You can try unpluging it for 5 minutes.

Philips 42 inch HDTV - "FlatTV" Plasma -- does not turn on.


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.

7 red flashing lights, won't power up..


Check the power board for capacitors with the tops bulged up. They are 3300uf 10v. There are either 2 or 4 of them depending on your set.

It is most likely a power supply failure and if there had been no signs of problems in the video display, it is probably the main power supply rather than one dedicated to the plasma display itself.
You might leave it unplugged overnight to give any stored charge inside the unit a chance to bleed off, the remove the back panel.
The primary supply is normally on a separate board and is characterized by having mostly larger components, including one or more transformers with black ferrite cores. The main supply will be associated closer to the AC input while the high voltage supply which may or may not be separate is not.
If you can locate the board with some confidence, check it visually for any signs of heat such as discoloration of board or components. If it seems OK it may be a candidate for exchange or repair by Philips.
I wouldn't advise removing and sending it before you talk to Philips to see if this is a familiar problem to them.
