I think you have dry solder joints on the tv. Either on the chroma board, the vertical scan board, the line output board, or on the focus board. If you are going to do this yourself please take all necessary precautions against electric shock and discharge all capacitors that you can as a stray spark from one can cause damage to your tv and yourself. If you are not able to do this find a competant technician. Good luck.

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.

This will be a block defect caused either by one of the flat flexible connectors to the screen giving a poor contact or a fault within the screen itself, which result in a replacement screen required

Did this fix your issue? I have the same issue with this model. If so, was it very expensive?
