I have a 50" phillips plasma tv that will sound like it's powering up like it used to, but then shut back off. The red light fpashes on the front of the tv. I opened up the back of it and the Alarm signal board flashes the code for D3V3. I cannot find any information on this code nor what to look at or replace. Any help would be great. WHAT THA HELL IS THE D3V3 THE ONLY INFO I FOUND IS THAT IT IS A LOW VOLTAGE SOMETHING BUT DOES THAT MEAN I HAVE TO REPLACE THE WHOLE POWER SUPLY OR WHAT ANY INFO WOULD HELP THANKS
I had the same problem with the same Model TV. after doing some research i found that i had 2 bad 3300uf capacitors. I made a video of the repair and posted it to youtube. the TV works great now! Check out my video! i hope this helps.
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.
Look on the power board for small capacitors with the tops bulged up. 3300uf 10v is the most common failure.
After finding this solution, I call a local TV repair shop to see if they carry 3300UF capacitor and to my luck they had them in stock. I took the Power Supply board off the plasma and took it to the shop. The repair guy took the old capacitor off the board and solder the new ones on the board. The shop charge me $35 for parts/labor and now my TV is working like new. Save me tons of stress and $$$$ from having to buy a new TV. Thanks for this great solution!

I have the exact same problem. Not sure what I can do to fix this. I cannot get my tv to turn on at this point.
