Question about Philips 42PF9966 42 in. HD-Ready Plasma Television
I have a Philips 42" Plasma, 42PF9966/37 that after being on will shut down and blink red with a clicking sounds like it is trying to come back on. Took it in and they said I need to have the power supply and regulator circuit. I have pulled the back off as suggested and do not see any issues with any caps. Is it a bad power supply board and if so, where can I get one? Thank you!
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.

Look for and replace any 3300uf capacitors on the board. Even if they do not appear defective visualy, they are probably bad.
