1 Answer

My phillipps 42PF9966 plasma turns on every night at 3:19 am and then off. It's starting to freak me and my husband out. I do not have any shows programmed for that time. Is this a defect or is my tv possessed?

You probably have a setting that automatically checks for updates. Change the setting to check/apply updates only when you choose.

FUSE KEEPS BLOWING WHEN POWERING 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. Link to a photo of the PCB. Make a note of the location of all cable connections then unplug them all. Un-install PCB, Check a 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. 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.

NO POWER ON PHILIPS 42PF9966/37


I had the same problem with a philips 42FD9932 and fixed with a great online tutorial. Just replace 3 capacitors available at Radioshack onthe the board. 2662, 2663, 2664 1 is a 1000uf the others are 100uf. Max Volts need to be over 25. It worked great, check http://dynamicorange.com/2008/06/25/fixing-a-plasma-tv/

Channel changes to channel 1 when your turn set off


Did you ever get a solution for this? I have a very similar problem. And yes, I realize this was posted 5 years ago. :) just a shot in the dark. Can't find a solution anywhere else.
