Question about Philips 42PF9631D 42 in. Plasma Television
TV is 1.5 years old. It's a Philips 42PF9631D/37 42" flat screen plasma. It won't turn on - just the red flashing light, seven times in a row, then it stops and cycles again, seven times in a row. Help, please!
I had the same issue with 2 of these sets. It ended up being 2 capacitors were bad on the power supply. They are located towards the bottom of the board, you can visually see they were buldging and leaking slightly. I replaced them with 2 I salvaged out of an old computer (of same values) and the tv works as it did before.

We had this problem once before, tv lasted about a year before it started the 7x red blinking light , had it fixed, 500 some odd dollars to repair, now it started happening agian, same problem, just 7 months after original fail, so now we are going to go MoldyMac's way and look for the caps and see if a old computer can help supply the needed caps. There is a temporary fix to this problem if you need the TV now and not later, although it is temporary , because the problem just gets worse as the "capacitors" get worse. I imagine this may be tough for those who have the TV up on the wall. Stand to the right of the TV and you will see the power cord under it, which looks like a standard PC power cable , put your hand on this cord and get ready to pull it out, use the other hand to press the power button which is conveniently placed right where you are standing, the green light will come on and you will hear two clicks from inside the TV, wait a moment and you will hear another set of clicks that sound like the TV is shuting down, this is when you pull the power plug out of the tv by pulling and wiggling it out, wait for the Green light to go out, then plug it back in, it will attempt to start agian without you needing to do anything else to it, where you will here the initial two clicks, and then the TV should come on, if it didnt then repeat the process agian and agian till the tv starts. Thats my temporary solution, but remember the tv may start on the first try but will get harder to start each day.

Took moldymac's advice. Seven blinks/no pic. Checked capacitors, both bulged at top. Pulled connectors out of board (careful!!), pulled the main board out (do not drop screws!!) took it to local tv repair guy, he soldered two new, higher rated capacitors. Put board back in, plugged everything back up, bingo- back up and running. Heck with Phillips service centers ($500 is b.s.). $58.00 total repair bill plus my time. Something else may be a problem next week, but this sure fixed this problem today. Simple and cheap. Playing today with no problems.

Hey, 9630 & 9631 Philips owners...we've helped fix a bunch of the problems on these plasma TV's besides the capacitor problem. Check us out over at AVS Forum, fix your TV set, see how many hours your plasma has been in use, fix the '4000 hour' glitch, etc.

The solution involving changing out the capacitors is spot-on. I had the same problem on Sunday, ordered the parts from digikey.com and had it in-hand by Wednesday. Now, with very minor soldering I am back in business. All told, it only cost $7.45 with shipping!!!

I HAVE THE SAME PROBLEM THE RED LIGHT BLICKS 7 TIMES

Did anyone who had this problem have problems with the screen before this happened? Our tv started losing the top half of the screen the other day, it goes white with different hues and the other half is fine. Turn the tv off and when you turn it back on it's ok for a while. Had it happen about 5 times in a hour or two and then not again for a day. This started about three days before tv wouldn't work at all and blinking light started. Just wondering if I fix this is my tv still going to need some other repair.

I have found that by using small space heater behind the TV for a short time before turning it on I am able to bypass the problem. Of course this isn't going to work if you don't have any space behind the TV. Might work if in general proximity but not sure. Good Luck. I'm not anxious to spend $500+ on a TV that's ~ 2 yrs old and costt $2000 to begin with. Seems to me there should be a recall.

I've done the capacitor fix and everything went great for about 6 months. Then, the same failure happened again.
I replaced the capacitors again (this time with a "better" part) and the fix only lasted 2 weeks before failing.
I'm ready to cut my losses with this TV and move on. It's a lot of money, but I can't have a TV that doesn't reliably turn on when I push the power button. Philips, I don't think that's too much to ask.

Same problem here. While researching this online, I came across this link to an attorney who has filed a class action lawsuit. http://chimicles.com/case/magnavox-television

Our tv was doing the same thing. Would not turn on and red light would blink 7 times. We opened up the back and low and behold there were the bulging capacitors. We took the mother board to our local tv repair shop and $70 later it is all fixed. Until the next thing goes wrong. Yahoo!! I would like to just put out there that there will NEVER be another Philips product in this house again! Thanks to everyone!

Awesome, I saw the bulging capacitors and came here after a google search. I knew they looked fishy, Geek Squad which came here on a warranty issue (unrelated) several days ago told me a repair would be about 500 bucks. Thats just off the top of his head w/o looking at it.
Future note, get the warranty at Best Buy its worth it, service is awesome.
Now I am going to get the 2 replacement capacitors and solder them in, I would rather have a tech do it but I didnt buy service on this one.
Thanks for the help I will update progress!

The problem is the Plasma Panel $1000.00 repair and Phillip knows about it .You can repair and replace everything on this tv . you will still have a problem somewhere else until you replace the Plasma Panel. There can be the same amounts of blinking ,but not everyone one has the same issue (figure that out ) A phillips repair center told me what the problem really is thank God for the honest people i suggest contacting phillip first get a complaint number from them and then contact consumer protection . like i'm doing . if it is going to get considered for recall this has to be done by all of us first .

I had the same problem with the blinking red power light on my 42" Phillips. Went to this forum and read moldymac's solution and also saw a video on UTube of a guy fixing a similar problem the same way. I decided to chance it and ordered the 2 capacitors online. My buddy, who is more adept at soldering, helped me remove the old parts and solder in the 2 new capacitors. Plugged it in and it is working like new. Cost me $6 for the parts, some time and a steak dinner. well worth it!!!

What kind of capacitors are we talking about, so I can get them before tearing my ste up?
Posted on Mar 20, 2009
Check the primary caps. I had secondary cap failures like what you are describing but eventually my primary caps went as well. They get hot and are rated for a limited number of hours before they fail too. Its all about heat making the set components wear out faster once the warranty time is exceeded (this is a science not conspiracy theory). Caps are usually poor quality to begin with and need better and more expensive components to get longer life.

Where do you get the stupid capacitors?

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. My tv just blinked red lights, had the clicking sound at first power on, but then goes black. No sound. No picture. Nothing. Just blinking red lights.
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..email@example.com

Where can i get these capacitors ,same or better qulaity
Posted on Aug 27, 2010
Thank God for people who share this kind of info. I just today replaced the two bulging capacitors as noted, and the TV is working again. Total cost, $2.72 for the two capacitors and about one hour of my labor. The estimated repair from a shop was $300 to $600. This was for a Phillips 50 inch plasma, only 4 years old. I WILL NEVER BUY ANOTHER PHILLIPS, however I will keep this one going for as long as possible (considering the price Ipaid). Can't thank you enough moldymac!

I replaced the 2 capacitors, turned it back on there's sound and no picture, in 15 seconds red blinking lights flash 7x again and again after another.

Same tv. same problem. same two capacitors. Took the board to a computer shop had them order the capacitors and replace them for forty dollars. Problem fixed. Just cracked a beer and am watching the tv to celebrate.

This fix it worked for me. I had the exact same problem. The explanation and the instructions above were a huge help. I took the circuit board out and called around to different repair shops. I am in New Jersey and the best price I found was $95 for parts and service. I put the board back in and the TV worked. I greatly appreciate the guidance. Thanks

Philips flat screen red flashing , seven times i unplug and plug it back again a few times it will turn on

Always test your outlet first. HDTVs are sensitive at the ground prong. Also, purchase an upscale surge protector. FIXED MINE!

Tailsfurse, thank you!!!!!!! The quick fix seemed to do the trick so far all tho it may not do it for long, moldymac suggestion will be next. I agree that there should be some kind of recall. I just cant justify spending 1500 for a tv and within 2-3 years having to shell out another 300-500 to fix it. What ever happened to quality made? Thank you again Tailsfurse....
