1 Answer

One minute its good, the next i get nothing.

Ive recently aquired a Philips 42PF9631D 37 from a friend who simply said it was having problems but when i got it to my place, it seemed to work just fine. it worked this morning but when i came home from work its just flashing a red light (in place of the green one it shows when its on) at me when i try to turn it on.

There is a eletronics parts thats has a cold solder on it. Maybe there is a cable or wire is barely touching on the connector inside the main pcb board. See technician to check your tv. Don't let this problem will continue, bacause some of the electronics will be damage.

I have phillips 42pf9631d/37 that wont turn on and blinks red seven times


I have the model Philips 37PF7320A/37 won't turn on and MOST articles on the Internet say it's the Capacitors capictors capictors..I checked all of them.

MINE WAS RESISTOR no. 3318 , a 100 OHM RESISTOR ON POWER SUPPLY BOARD.

I BOUGHT REPLACEMENT FOR .99 CENTS SOLDER IT, AND EVERYTHING WORKED!!!

THAT WAS ALL IT TOOK.

JUST A SUGGESTION..
1. CHECK FOR BULGING CAPACITORS (90 PERCENT OF THE PROBLEM)
2. THEN CHECK FOR RESISTORS WITH MULTIMETER ( FALLS INTO THE OTHER 10 PERCENT OF THE PROBLEM.)

TELL ME IF THAT HELPS..normanw1@yahoo.com

SOUND BUT NO PICTURE - Philips 42PF9631D 42 in.


Unplug the box's power cord for 5 minutes and wait for it to reset, plug it in, wait another 3 minutes for the box to reboot, then power up the box. If that doesn't fix it then you might have to call your satellite/cable company.

Tv wont turn on


loud noise ? ! just indicate that the main power supply capacitors are bad, or sometimes is just the ceramic filters.
undo the back and check for any blow capacitor or burned components.
the new power board cost 139.99 on ebay

Philips Plasma won't upgrade firmware.


You need to copy the autorun.upg file from the sub folder to the root directory of the zip drive. I had the same problem and it worked after I did this.

Philips 42" Plasma


It's likely the upper Y-module but both the upper and lower could be having problems - just nothing noticeable in the lower half of the screen as yet, is my guess..
This is not a job for a layman and you'll need some fairly sophisticated equipment to troubleshoot the boards, not to mention being able to read schematics and understand waveforms. Hence, my best advice would be to take it in to a reputable shop and have it estimated...
