Question about Philips 42PF9630A 42 in. Plasma Television

2 Answers

The TV normally has a green light illuminated in the lower left. Now there is a red blinking light (7 times) and the TV is not responding to any TV buttons or remote commands. If I unplug and plug back in, the lower left light is green for a couple seconds then reverts to the flashing red light After about 15 times unplugging it comes on Any ideas?

Philips Televisions are legendary for having faulty power supply capacitors.

In order to prevent really bad things from happening, the TV does a two-stage power-on. It first does a basic diagnostic test, and if that fails, it stops it from going any further.

Philips tends to use cheap capacitors, use capacitors that are somewhat under-sized for the job, and also seems to be pretty bad at soldering.

Personally I've got my Philips LCD TV opened up on my workbench for that exact problem.

Most repair shops would replace the whole power supply board ($150-200 part plus labor), while most DIY fixers take a stab at replacing the obviously bulging and failed caps for less than $10.

The television has an internal problem - the 7 flashes are a code generated by the processor identifying the area of the problem for the service technician.
You will need to get it looked at by a service technician - unless you can source a service manual and are able to fix it yourself.

Here's something that might also be useful. After you turn on the set, and get the regular red blinky lights, hold down the Device and Menu buttons together for about 5 seconds.
The Power light will start to flash in a two digit sequence.
For example, 3 flashes, then 7 flashes = 37.
Here are the error codes, and the corresponding problem:
12 = No error detected, check power supply.
32 = Lamp Cover is open.
33 = Air filter cover is open.
34 = Lamp abnormality
36 = Light Engine (DMD or Lamp Fan stopped)
37 = Exhaust or Lamp Ballast Fan stopped
38 = Lamp Temperature High
39 = DMD Temperature High
41 = Short is detected
44 = DVI cable between FMT and Engine disconnected

50px1d-uc When I try to turn it on, the red power light blinks, I hear a click, then the light turns amber then back to red. Usually I'd hear the click then it would turn green and the tv would work...


I came across this in a manual
-Without CableCARDTM : Illuminates red in
standby mode, Illuminates green when the
TV is turned on.
-Inserting the CableCARDTM : Illuminates
orange in standby mode, Illuminates green
when the TV is turned on....
You might want to check your cable card. It seems to mimic your problem. Try taking the card out and gently clean, with a dry cloth, the contacts/strip. Then take some "canned air" and blow out the card socket from the side to dislodge any accumulated debris.

Stand by light flashes red on powering up with remote and the green light flashes approx 15 or times before the screen illuminates.


thats pretty normal, it takes a good second or two to warm up and the display to turn on(at least0, you get the green flashes as you hold for on, 1 sec is a long time at times, lol, be patient, no problem with your tv!

FLASHING POWER RED BUTTON 7 TIMES


I believe that is a bad power supply board. You can unplug set ,open the back access panel and look for swollen electrolytic capacitors they will most likely be slightly rounded on top instead of flat top like the others.Not sure if just replacing caps is enough we mainly swap out whole board.Some models' replacement power supply is slightly different from original in that a couple of the plugs are in different spots and require an extension cable.
