Question about Philips 47PFL7422D/37 Television
Tried to switch on this morning and the Philips logo comes up as usual, then screen turns off and white light just blinks continually. Tried unplugging for a while and plugging back in but to no avail. I guess this is the main board, but could it be caused by adjusting the service menu? Surely not? I know they warn you against this but surely there's nothing that should do this to the tv? It was working fine all day yesterday until I switched off last night. I'm just worried that they might be able to tell I've been into the service menu and not refund my money.

If the TV has sound and no picture, it might be the timer settings. There is a fix for Philips 20PF5320 here

just call philips and they will send you a new t.v.! it isn't a recall, that would be bad publicity!! i spoke with a philips representative yesterday concerning my 'possessed' television. a gentlemen informed me that philips has a 'rapid replacement program' for the described 'possessed' t.v. set. simply provide model and serial numbers, time and place of purchase, then provide street address for fed-ex delivery. approximate time of arrival is 10-15 days. you are directed to package and return the old set to nearest fed-ex pick up site. i am super excited that i took the time to call philips support. i think that i spent a total of 10 minutes on the telephone; it was time well spent. oh yea, here's the number!

The TV is on protect mode.
Try first leaving the TV power cord unplugged for some times, let say one hour or so.
Also ensure that the fault is not coming from a faulty receiver box sending bad signal, check if you get same problem with no receiver box or dvd connected.
If that does not work, and you keep having a flashing led on front of the TV, and tv turning off by itself after a while, that indicates a fault condition.
The flashing light indicates a diagnostic state called protection.
When the TV goes on protection there are only two possible reasons.
1The internal circuits are jammed because of electrostatic charges accumulating on capacitors, or because of a wrong voltage read by the main chip on your monitor controller board. this started the protection circuit.
2 The protection circuit detected a wrong voltage or abroken contact, identified an internal fault and kicked in , startingthe flashing light.
If you are in situation one, then theTV will reset just unplugging power cord for one or two hours,sometimes even minutes.
If you are in situation 2 , then there is an internal fault.
Common faults that can occur are a blown capacitor on power board, a convergence IC has blown, or a fault on Digital board.
Check also the video cable or any external connection cable, if the cable is shorting, or the connector is bad, you can get same flashing state because of the video cable.
If under warranty contact the manufacturer ringing the number on the user manual
If you want to repair at your own expenses, just locate any good qualified repairer.

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.
