I do agree with the tech but if the green led don't come on and the 7-blink error code is still there. check the connector from the logic board that will be the board under the small signal baord. The small signal board have the AV input on it. Check the connector from the logic board to the power supply there should be one connectore btween those 2 boards. On the power supply side second pin from the left it will say Vs_On if the set has 0 volts the proble is the SSB or the logic board. how to determain that is to Use 2 Jumpers to short J8003 & J8004 on the left edge of the PSU (see figure below).
Use 1 Jumper to short CN2012 on the lower left part of the Logic PCB (this will supply a 100% White signal to the Display).
Plug in the AC to the PSU thru CN8001.
If PDP panel operates with White field screen then problem may be the SSB.

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.

hello, amigo if the all the caps are godd then you have to replace the power supply board. don't try to fix it this is not an easy task. you are looking at almost $200.00 with tax an shipping. just go to google and type your tv model # and ask for the power supply board or just look for the part# on the board itself. good luck
SOURCE: Why do i have red lines on my philips plasma tv?
if the lines are going horizontally across and look like someone took a thin magic marker and marked across the screen, you have one of two problems, either some scan ic's have failed or you have a flex cable coming loose from the panel. Either way it will require repair. If it is the flex cable the cost to repair will be beyond the tv's worth because the whole panel needs to be changed to fix this. If it turns out to be the scan ic's, they can be changed or the board the ic's are on may be changed depending on how the repair is approched by the tech. But the cost would be reasonable around 200 to 250.
Good luck
