First of all, thanks to all the folks that have posted information on the problems of the Philips 9631 Ambilight televisions; there is some truly selfless stuff on here. Hopefully, no one has relayed a solution to my problem because after about 5 straight research hours online, I simply cannot peruse these troubleshooting threads anymore.
That being said, I relay my tale...
I bought the Philips 50pf9631D/37 plasma with ambilight from a Sears in around August of 2006. It worked fine for a couple of years until late 2010, when I started to get the 7 blinking light error code. I performed the Unplug/Plug trick for months, no telling how many times, and it got progressively worse. It got to the point where I was doing the damn trick forever. Now, I did some research and came to the conclusion that it was the aforementioned capacitors 3300uF 10V 105C located in the ...59 and ...60 slots.
I have some soldering experience, having been a tech in the Navy, so I decide to take on the project. I put the tv in position to finally receive some much needed maintenance. For some reason ( I had the set on an entertainment center when I did the trick) when I moved the tv I decided to give the old girl another try just to see if it duplicated the discrepancy, as anyone who has troubleshot electronics knows can be a huge PITA. What do you know? No 7 blinking lights. As soon as I plug the set in, I get a solid AMBER light and nothing happens. No screen, Ambilight, audio or anything. Dead. I don't have to try to turn it on, only plug it in and the AMBER light comes on NOT RED. Also, it is steady. The audible clicks that were so common before have disappeared. I have googled and everything else you can think of trying to find a reference to it and nada.
Now, I have taken the panel off and replaced the same capacitors which everyone else who has had this problem has done with great success. They were indeed blown, visible bubbling on the top. Alas, this did not solve my problem. I still have the steady amber light upon plugging the set in. It is surely possible, indeed probable, that I relied on the unplug/plug trick for too long. What I don't know is what damage I could have possibly done save perhaps blown a fuse, another of the suggestion/solutions found on this very thread. However, if my problem was the fuse in question which was alluded to earlier (the one right after the power wire connection on the PS) I believe that the LED light would not receive power because fuses sever current.
I have attempted to look at the schematics and block diagrams of the chassis for this tv, the only problem is they are grainy and illegible on the pages that I need (error code page, and diagram of the power supply, for example). The audible click or lack thereof would seem to be a huge clue as to what is wrong, being that the click was there with the 7 light error message and that it is notably absent upon plug-in now.
1) 50 inch plasma 9631 model. Had 7 blinking RED lights. Performed Unplug/Plug on it for months, getting to point of futility.
2) In Troubleshooting mode, attempted to duplicate...no RED lights....steady AMBER light upon plugging tv into wall recepticle. No audible click.
3) Replaced capacitors C8059 and 60. No joy. No change in problem. AMBER light remains. Performed inspection of rest of visible caps and they seem good to go. I stress 'seem'.
4) There is no reference on the internet to this problem as far as I am aware. Would really love to know how the AMBER LED light gets powered up, as that would let me know if there is something as simple as another capacitor blown or perhaps an electro-magnetic relay that is stuck. Any help with what the steady Amber light means would be a huge help.
5) I believe the problem to be prior to the failing capacitors in the circuit, however, my lack of television knowledge combined with my lack of an adequate diagram hurts my chances of finding out what exactly is messed up without testing each and every component with a multimeter. Needless to say, I'm trying to avoid that.
Thanks for any and all help with this matter. I'd love to be able to get this tv working with just a little willpower and determination and not spend more money than it would take to just buy a new one.
If you got through this whole post, you are a trooper and deserve my respect and thanks.
