Power supply failure- I found the filter caps were all cooked dry and the yellow glue they use in this power supply turns conductive where it turns dark brown. Unsolder the devices and feet on the heatsinks and remove them along with the stand-up driver board. Change all caps-1000u/16V, 470u/16V, 47u/50V, 10u/50V. Scrape and pick off the brown glue from all devices. Re-assemble. Mine would then fire briefly and I noticed only one fan was turning. Removed the fan and found the bearing was seized in it. Power supply will now run properly with the defect fan unplugged. I won't service one of these again-the picture sucks!

I think the transformers in these units are the problem not the "power board" I have a symphonic that had a bad transformer in it two legs were not putting out any voltage so I replaced the whole main board for about 50 usd. I may put a small fan inside to move some air around that transformer so that it stays cool

Check to be sure that there is no voltage on the input line. You don't indicate what input you are using. Since the set appears to work without an input connected, try looking at the input cable. Also, if the problem is internal to the set, shorting the input jack would cause the same behavior. Please update this with what you find.

SOURCE: fujitsu power supply shutdown goes to standby mode. no picture. If I turn it off for a while I get great picture and after a while it shuts down and goes into standby mode. Is this a power supply that
This is most likely caused by the Main Power pcb.
See Fujitsu Service Bulletin on this problem in the P42HHA10 model. -see link below
A similar Service Bulletin is probably available to suit your model. A competent service technician should be able to implement the service bulletin.

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.
