Philips 42PF9631D HD Plasma - Page 46

Here's my post-capacitor data breakdown for my twin 9631's:

50" 9631: Caps changed in September....Hours Of Use counts are 8,596 & 6,548....the 9631 has put on 2,048 hours since the September cap change.....TV turns on with sound/TV both on in about 15 seconds (2 seconds quicker -- tops ! -- if it's already warm)...."CLICK-OFF" takes 15 seconds and is lengthening.

42" 9631: Caps changed in October.....Hours Of Use counts are 9,405 & 7,273....the 9631 has put on 335 hours since the October cap change....TV turns on with sound/TV in about 13 seconds....."CLICK-OFF" takes just over 2 seconds.

hmm ok, it prolly is based on cable mostly, but the click off is whats drastically different for me. not too concerned though. thanks for all your help. ill time mine every couple of weeks, maybe like once a month, until i start to notice some change.

It's a curiosity factor more than anything....when the delay gets to about 5 minutes -- 7 minutes tops -- then you know the caps will probably go within weeks/months and you're back to 7-blinking LEDs.

Worst thing is you have to replace the caps again....now that you've done it, should be easy.

I have a 50 inch (50PF9631d) that I replaced the caps a while ago, maybe 18 months back, thanks to this forum. Now I'm having the 7 blinking error again. I have not been able to get the TV on at all. I replaced the fuses and it didn't help and when I look at the caps that were replaced they look fine. Should I just replace the caps again before I try anything else? I have been reading this forum and there has been a discussion about resetting the time, what is the benefit of doing that?

(1) If you got the 7-blinking LEDs and only the blinking LEDs, it has to be the capacitors again, from what we learned.

(2) It's possible that you inserted bad capaacitors or maybe need to check the key fuse (go back a few pages to read about the bad fuse problem). That could possibly be setting off the 7-LEDs even though the caps are GOOD.

(3) Go into the Service Menu and reset the 2nd hours counter to "0000" assuming it's at 4,000 and stuck. No, this has nothing to do with the capacitors but if you wrote down the 2 hourly counters when you did the switch the last time you'd know how many hours the TV accumulated and if it was possible/likely that the caps wore out again. Generally, they should last about 7,000 hours but on my 50" it was closer to 4,000 or so.

Thanks, I already changes the fuse and that did not help. I will do the caps again. It was august of 2009 last time I replaced them and it is our main tv, so it us on all the time (probably 10-15 hours every day). I will let you know.

Did you write down either of the hour counters ? Write them down again now after you replace the capacitors (well, the 2nd one is gonna be stuck at 4,000 hours for sure) so you can tell how long the TV gets. Re-set the 2nd number to "0000" and check back in 6-9 months. Service Menu instructions are a few pages back.

Yeah, 10-15 hours a day probably means the caps went -- you got 4,000 hours for sure and maybe as much as 6,500 - 7,000 if it was close to 15 hours a day.

Report back...BTW, order new caps from DIGIKEY and get the 10v ones -- don't substitute a new brand or voltage size.

hi everyone, Ive just been given a 9631 ( 42 pf9631d/10 to be precise , dont know what the difference is between mine and a /37 ), that is faulty. When i plug the tv in , the led goes green and the tv turns on with two clicks, there is no picture or sound but the screen does go slightly lighter ( backlight possibly ? ) and the two ambilights turn on, the tv does not respond to the remote but the led does flicker when buttons are pressed. if i press the standby button the tv will not turn off. Every two minutes or so the tv turns off by itself and then turns back on by itself. i have taken the back off the tv and there are no obvious faults or blown caps. I was just wondering if anyone had any ideas, or the service manual which includes fault finding procedure. many thanks in advance

First, turn the Ambilight's OFF the next time the TV is on. If you are having a problem powering on the display you don't need to also try and turn on the side Ambilights, especially from a cold start.

Second, does the LED blink any code ?

Three, can you see anything if you hit the Philips remote MENU button ? Check the ERROR messages in the Service Menu (you know how to access that ?), don't touch anything, just scroll.

Fourth, there's a RESET button to factory resets or something in the
Service Menu...when I get home tonite I'll check where it is. That MIGHT help -- not sure, it might just be picture settings, can't remember.

Wait a sec.....is the TV turning ON or trying to turn on when you just put the plug in...or is it already plugged-in and you are hitting the POWER ON button on the side of the TV or the remote ? If the TV is attempting to POWER ON when you just plug-it-in, this sounds like capacitor-related.

Hi, thanks for your reply, yes indeed the tv turns itself on without any input from me at all, i am not pressing any buttons on the side of the tv or on the remote, the only way for me to turn the ambilights off to help the situation is to physically unplug them. also i cannot get into any onscreen menu via the remote as there is either no response to the remote or no picture. lastly i have no blinking led , the led stays green all the time and only flickers when the remote is pressed

In the last 10-15 pages of this thread I think somebody else had this problem....go back and check.

Also, somebody here put up a PDF of Service Technician codes/problems that might help.

Finally, try the PLUG/UNPLUG thing even if you aren't getting the 7-blinking LEDs.

Is the outlet good -- it powers up other TV's ? Surprised you are not getting any ERROR code from the LED.

I have managed to obtain the service manual and the latest upgrade for the tv off the internet . The service manual is very good with fault finding solutions so as soon as possible I am going to investigate further. Also on ebay I noticed someone selling a couple of capacitors plus a resistor which they claim will cure the problem i have . As i mentioned in a previous post , the model of my tv is 42pf9631d/10 , in his auction he says it will repair model number 42pf9631/37, so i emailed him about the slight difference and he replied " hi, you will need to check what power supply you have fitted, if it uses the lj44-00101 then yes they will fit " , so i will have to check that when i get home from work.

the url for the ebay auction is http://cgi.ebay.co.uk/ws/eBayISAPI.d...:X:RTQ:GB:1123

Was never aware of the difference between "37" and "10" on the model number but I guess it could indicate a slightly different PSB. You should buy NEW capacitors and resistors from DIGIKEY -- use the eBay auction as a backup.

Can you post the Service Manual here as a PDF ? Thanks !

I'm wondering if the 50PF9630A and the 50PF9631D have the same boards in them? I searched both 9630 and the 9631 boards and couldn't find and answer other than "I think so." I'm wondering this because I will be getting a 50PF9630A soon and I might attempt to fix it, but don't know if the 50PF9630A has capacitors named C8059 and C8060.

I searched though the 50PF9631D service manual for the terms 3300μF, 10v, 8059 and 8060 but found nothing pointing to those caps. I was going on the hunch that if I found it in the 50PF9631D service manual then I'd find the answer in the 50PF9630A service manual.


p.s. I posted the 50PF9630A service manual link in the 9630 thread.

I found some very good youtube videos of capacitor testing.

Part 1 http://www.youtube.com/watch?v=GZMQW...eature=related
Part 2 http://www.youtube.com/watch?v=4iTR-...eature=related

Even if it has the same capacitors, the board is probably different.


They're there, trust us.

There are different boards in the 9631 depending on early- or late-models.


Thanks !

No, those are the LOCATIONS on the PSB where the capacitors are located.

3300 uf 10v is the model that we order from Digikey or another supplier. Some folks went with 25 volt 8,000 hour caps but they could be a tight fit on the board. Go with the 7,000 hour 10v -- should last you YEARS.

I dont think i can post the service manual as i think its too large at 35mb but the link is http://www.free-service-manuals.com/...Manual_L89520/

The power supply board in my tv is totally different to the 42pf9631d/37. On you tube i found what looks a great video about repairing my board but unfortunately there is no sound !!

philipsphanatic , you have pm

Hi all. I've been a visitor to this forum for years. I had the blinking red light issue long ago and have replaced the caps. I'm an avionics technician so am very familiar with electronics, soldering etc. I've seen mentioned here and there about sprinkles but I don't think I've read about any specific fixes. My 9631 42 inch gets white sprinkles across the screen during dark scenes and then fades away. It's only noticeable up close but happens with any input whether tv or dvd. It's been doing this for years and I've just lived with it. I have the service manual. Does anyone have any clues as to what board I should be focusing on? It would be nice if this too is a capacitor issue. Thanks for any help given. This is a great forum with a lot of contributors.

@krgpsman

I remember seeing a solution somewhere in this thread. I think the fix was a voltage adjustment, which voltage I don't remember.

KRG, I believe it was a voltage issue on one of the circuit boards -- Y-Board ?

I don't recall a DEFINITIVE fix ever being recommended and I don't know that too many have/had the problem (the blinking 7-LED capacitor and BSOD problems were much more frequently posted here).

Mine is red speckles, and it fades -- or rather, the TV brightens which lessens their visibility -- once the TV is warmed up. You can still see them on dark scenes esp. when I am closer than 7' or so. Sitting back 9-10', I have to really look for them to see them -- so I live with it. Unless a real simple and easy fix was found, I wouldn't want to risk screwing up the TV since it works great and I have the interactive Ambilight feature.

You can use ADVANCED SEARCH or GOOGLE or read back a while here or on the 9630 Thread, but I am not sure if a definitive solution was found. If it was, it might be tricky to implement, in any event. I would go back to BEFORE mid-2008 on both boards to see the post(s) on that problem; I also think someone might have posted here on it in the last 18 months but don't quote me. For me, I have chosen to live with it but if an easy software or circuit board adjustment would fix the problem, I might try it.

Let me know what you find.

That's what I recall ....I'll try and Google "9631, sparkles, red sparkles, voltage, AVS Forum" and other such words later tonite when I have time.

That might save time rather than reading/scanning a few dozen pages on the 9630 and 9631 Threads.

Found this from about 2 years ago from someone with a 50" 9631:

"I have green and red "speckles" that are very distracting within the dark/black areas of the picture...."

Somebody's response:

"I had the same problem with my TV. It was a horizontal problem with different shades of color, and black spots. I replaced my Upper & Lower Y-buffer boards. Your Y-sus board should be okay since it still powers on the screen. You should replace the Y-buffers Upper & Lower, and it should work."

Not sure how cost effective that will be unless you can get 2 matching/working circuit boards on the cheap. Let's keep looking for some kind of adjustment that can do the trick; might be simpler and is definitely easier to do and cheaper.

WHEW !!!!

My building had a transformer blow, electrical box blew out. Power cut and then eliminated. My 50" 9631 was on at the time, it turned off and started blinking 6 Red LED's. I thought the power disruption might have fried some circuits.

Fortunately, the Monster Surge Protector did it's job......when power was restored, TV fired right up. No problems, appears totally fine.

Hey, I think the red speckles may have gotten fixed from the discharge !!

Thats a good advertisement for surge protectors. I have had slight progression on the tv as I now have a red blinking led ( yippee er I think ). I have error code 25 which according to the service manual is " supply fault " . I am hoping this will be the main supply board as i have managed to obtain one from ebay for a pittance, although after a bit of research it could also point to the ssb ( small signal board ). Could i just ask someone with a working tv to describe the start up procedure, On my tv before it decided to display an error code, as soon as i plug the tv in to the wall the led would go green the tv would power up and ambilights would come on, now i know this is not normal , but could someone tell me if when they plug their tv into the wall does the led come on red, and then turn green when the standby button is pressed on either the tv or the remote ?, many thanks in advance

TV should NOT come on and nothing should 'fire up' or light-up when you just plug in the TV.

When the TV is broken -- when the capacitors or something else on a power circuit board is malfunctioning -- then putting the plug into the outlet creates a 'surge' that can turn the TV on. In fact, this is the ONLY way to get the TV on with the 7-blinking Red LEDs. Plugging in and powering-up simply gets you a temporary green LED and then goes Red Blink 7.

When the TV is plugged in you should hit the POWER ON button on a remote or on the side of the TV and it should go GREEN right away. Then the picture appears 5-10 seconds later.

When the TV is broken, after you've used it a few hours, the TV may stay plugged in and it should re-start if the TIME OFF is under 90 minutes. If not, PLUG/UNPLUG (usually not too many needed since circuits are still 'warm').

When the TV is broken, you can't just plug it in and then hit POWER ON -- the very act of plugging it in activates the capacitors and fires up the TV (or attempts to).

1 thing: if you get the TV on or even if it has power for a few seconds, get the Ambilight OFF.

Is your TV able to work ? Do you have to do PLUG/UNPLUG ?

Here is a URL of a video of the board repair for the 50" model (and has sound) if that might help. http://www.youtube.com/watch?v=OsJSzYVUWVA

By the way, next month marks five years of good service from my Philips 50PF9631D! I had two issues over that time: the first was covered under warranty in 2007 and the other was the capacitor replacement which I did in 2010 with lots of help from this forum. Still has a great picture and I still love my Ambilight!

Retex, congrats and here's to many more years of use......what was the warranty issue ?
