Question about Philips 32PF7321D 32 in. LCD Television
Actually is a 32PFL 7623D / 10 ...Has always been slow in response to inputs, learned not yo overload input by multiple commands (usually in frustration) ,,, recently downloaded software upgrade from Philips site ... now will only show one channel at fixed volume etc. ... no input works either from remote (batteries changed) nor from set located buttons ... occasionally will respond to switch off, but then restarts spontaneously after about 15 seconds ... to the same channel. set is approx 5 months old (so will be going back to supplier I think) ... any ideas what might cause this ... or are these machines just too damn clever for their own good?

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

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.

First of all the software update may not have been done yet, when tv's go through an update (depending on which update) the set can turn it's self off and seem to be done, but you need to wait it out and the set will turn it's self back on, Wait it out for about 30 minutes before doing anything. be paitent. UNPLUGGING THE SET CAN DAMMAGE THE TV DURRING A SOFTWARE UPGRADE!!!
If after a LONG period of time try unplugging the set and re-setting the micro. But only as a last resort!
If the upgrad failed and you can't get the set to function properly you need to change the ssb board. If the set is in waranty, waranty should cover this.
