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.

One very common problem encountered on many Philips models, old and new, In some cases, the SSB board has to be replaced as the resistor on the PCB on the back of the CRT had to be fixed. In other cases the Y Sustain board had to be replaced. If the problem is not due to these two issues, then the capacitors will need to be replaced as they only have a fixed guaranteed life. Thus, it would be wise to take out an extended warranty on Philips due to this common repair issue which often occurs after the limited warranty has ended. Or you could just call your local repairman. There are lots of websites on how to fix it yourself on google. There could be many reasons. Hope this helps!

change the backlight (cold cathode light) on your monitor.. If you are able to open the back of your lcd monitor carefully, the backlights are located at the upper and the lower part of the edge .. replace it with conventional cold cathode lights(protective tube was removed)... there are also instances that backlight was good but the ballast transformer is burnt. Replace the ballast. Its very cheap to replace that.

Are there any blown caps on the PSB-power supply board. Most sets have sammy boards and they used very shotty caps. If there are no visual clues being a poped cap at the top (X) they simply often do vaporize and dry out. The YSUS-Main and the 2 Y buffer boards control the picture OSD-on screen display. Your not getting any of that. So power supply is where you start first. The YBU-upper and the YBL-lower control the upper and lower OSD the Ysus main control both of them. Usually if you have one in the door you have to replace all 3. But not always. If you were to replace any of the boards I would replace the YSUS-Main, or get the board reworked at a pc repair shop that does board level test and repai. Its more cost effective.
