Question about Philips Televison & Video

1 Answer

Why does my Philips TV randomly turn off and back on?

Called Philips, they said if I unplugged it for several minutes and plugged it back in and it still turned off and on by itself then it had to be a hardware problem. The remote quit working shortly before the problem started also. Changing batteries didn't help.

I think some of the capacitors at Tv power supply are faulty. By doing what Philips suggested, you actualy try to discharge capacitors. This trick could work, if capacitors would be fine. Your tv needs to be checked by service.

SOURCE: Panasonic 32" HDTV keeps turning off

Check or have a repair tech check connectors AP1 and AP2. Vibration rattles the power supply board (a crappy design, as the board is almost "floating") and causes the wires in the connectors to break, and may make intermittent contact. Heat may also cause intemittent contact. A very common flaw.

SOURCE: Sharp Aquos turns itself off

How many times per second does the POWER led blink? (dont worry about the OPC).

1x per second (constant, steady blink) = bad inverter/lamps
2x per second = bad power supply
3x per second = bad main board

You can buy the parts online and fix if yourself!!

SOURCE: Vizio shuts itself off

There may be some components failing in the power supply or one of the circuit boards that are causing too high a current pull.

I realize that this answer is very vague. Without doing proper diagnostics, it is impossible to guess at something like this.

Out of warranty repairs on these sets can be very expensive. I would suggest that if the set is going to be expensive to service, it would be best to replace it with a known brand name that offers an extended warranty with local service. You will pay more, but you will have dependability and better quality.

Philips 42plf7422 RANDOMLY SWITCHES INPUTS


There is nothing wrong with the TV I assumes. Have you tested it a hard reset? If not do a hard reset and check. Unplug the TV from AC mains wall socket, and re-plug it back after 10 minutes or so. An overnight unplug will be more effective. This must make the TV to a hard reset. If it do not help you, you have to enter its service mode options to make it a factory reset. If you wish to get more details about how to enter the factory mode check this link. http://electronicshelponline.blogspot.com/ Service mode and alignments to many brand TVs, including Philips models, have been discussed in detail there with illustrations. Pull up older posts there, and surf the site with patience.

Picture keeps going out on Philips TV 47PFL3704D/F7, 2009 model. The sound stays on. It happens very randomly-may be fine for several hours, may happen every few minutes. Also happens when playing video...


I think that the connectors from the backlight inverter board that go to the LCD panel's backlight are a bit loose which explains why it comes back on when tapped. I am positive that unplugging and replugging the inverter cables should do the trick. WOuld like to do it yourself? It requires you to open up the tv ofcourse.

I need help tv plasma phillips


There is a firmware that can be updated via usb from philips. This fw was used to correct the tv powering on with no picture randomly (they called it a maintence session) but it was a problem. The tv would power on on its own and do this..


If that doesnt take care of your problem then the problem is with the main control board. or ssb

I called the Philips help number (1-888-PHILIPS) and the tech had me turn off the tv and then unplug it from the outlet, wait 1 minute, then plug it back into the outlet, then turn the tv back on. It reset the menu memory and it is now back in the middle of the screen where it belongs.
