I had the Same issue. on a 50PF9431D/37 set. Many Plasma Set's use a LJ44-00118A PS-505-PH Power supply from Samsun. Know 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 conections. 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.

Turned off


Greetings!
You have said that your TV is new, therefore it is underwarranty. Better not to remove or touch any parts of your TV that will cause more damage. Bring it to the center for check-up.
Thanks

scanning the channels would not have done damage, the tv probably just sensed the unplugging of the power as a ''spike'' in the power line. Just let it sit unplugged for a while and then plug it back in, should turn back on again. also, if you are on cable or such, the scanning of the channels should actually be done, in ordr to see all available channels when the vcr is not in use, or if not, just set it to channel 3 or 4 to see it through the cable box. ps.. In the future, don't buy tv/vcr / dvd comos, the main reason why most peole buy those things is so the kids will leave the bigger tv set alone, problem with that is- kids will be kids, and sooner than later they will stick something the player's slot and screw the unit up- that leaves the tv by itself, which they will not want to see if the player is not working. so you are out of both and the kids are back taking the bigger tv away from you. best thing is always to buy separate units (vcr/dvd player combo's or separate units are usually cheaper to buy separately along with a dedicated tv than one of those all in one units. something goes wrong, just fix or buy a replacement for the system. and you get to keep your own tv.
