I have a Philips 50" Flat HDTV model 50PF9431D/37. Problem with screen turning on. I get sound. I get 9 quick flashes in red. Then after unplugging and plugging back in several times. It then blinks...


I have the exact same problem! I have it hooked up to a power strip now to unplug it by flicking of the power strip and waiting for the red light to go out then I turn it back on while Channeling up 10 X's and then down and up until it comes on. I listen to the sound of the switch which it comes on. I turn it off if it is faint and then back on and channel up. Crazy process but it's been working. It takes about 10 minutes everytime to get the TV on until I get a tech to come out and look at it. The capacitor keeps a charge which is why the light is flashing with a code for 60 seconds./JJ

Philips 42 inch HDTV - "FlatTV" Plasma -- does not turn on.


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.

Philips 42PF9956/37 Plasma TV - Looking for y sustain board


it isnt the Y-SUS board, it is the Power supply, iv fixed this exact problem twice in the last month, try turning the tv on, and when it turns green, unplug it real fast, while light is still green, after 15 seconds plug it back in, then hit the power button, if it dont come on, hit the power button again, this time, as soon as it turns off, hit the power button again to turn back on, sometimes you can trick the tv and it will turn on, at least i was able to do it, and once it comes on, it should work fine, untill you turn it off again.

After you remove the back cover inspect the power supply board for swollen or bulging capacitors. Pull and check any capacitors that you suspect to be swollen. Next, look for a sticker in the upper right hand side of the TV set. Use the values you find on the sticker to calibrate the voltages on the power supply board.
