Re: Westinghouse LD-4655VX - My First LED
I had the same problem with the same TV. I took it apart and the main board looked okay. I unhooked the two cables to the LED panels and the TV powered-on (but was very dim and I needed to use a flashlight to see the image). I then plugged-in the LED panels one after the other and found there was a problem with the right LED panel.
I took the TV apart and the right LED panel looked fine, but I found a short in the cable. The cable's insulator was worn through where it wraps around the aluminum heatsink of the right LED panel....

Re: Quirky 42" Phillips Plasma TV (42PF9631D-37)
I found a few hours to work on the TV over the holidays. I replaced eight of the larger capacitance capacitors (2x 1500microF 10V, 6x 2200microF 16V) on the PSU with new Rubycon and Nichicon capacitors from Digikey. The TV now powers-on and works normally about every three out of five attempts. The other two times out of five I try to power-on the TV and it still has the same problem: it does not power-on and the LED on the front of the TV blinks a 6-3 pattern.
I still don't know what the problem is, but this is...Leave a comment:

Re: Best Buget ESR Meter?
Using what phone number? I couldn't find one. Could you? Their "Contact Us" section listed no contact information; no phone number, no email address, no outside website, no physical address. I sent them a message through Ebay, though. If I get a reply, it will probably be from a representative who knows less about the item than I do. That's why I posted my question here: to get the opinion of someone who knows what they're talking about.
If this tool will not suit my needs (checking for a faulty capacitor), could...Leave a comment:

Best Buget ESR Meter?
I'm an amateur. All I need is an inexpensive tool to test if the capacitors I have are faulty. Would this tool ([url]http://www.ebay.com/itm/Capacitor-ESR-Inductance-Resistor-Meter-Transistor-Tester-Detect-NPN-PNP-Mosfet-/261284553259?pt=LH_DefaultDomain_0&hash=item3cd5c5e22b[/url]) work? It doesn't say that it comes with test leads. Would I need to solder some to the PCB?
The capacitors I am testing are 2200microF, 25V and 1500microF, 16V. What size resistor should I use to discharge them before I test them?

Re: Quirky 42" Phillips Plasma TV (42PF9631D-37)
Update:
Now the TV's audio consistently turns-on, but before the video turns-on, a relay on the psu board clicks once. Then the audio cuts-off and the led on the front of the tv flashes 6x(slow)3x(fast). The led on the psu board is also illuminated. I read elsewhere that this is indicative of a problem detected on the psu board.
I bought a DMM and checked some voltages. There is a sticker on the PDP with a list of recommended voltages: Va=65V, Vsc=-185V, Ve=110V, Vs=197V, Vset=195V. The readings that I saw...Last edited by FlyingHigh85; 11-16-2013, 06:19 AM.Leave a comment:

Re: Quirky 42" Phillips Plasma TV (42PF9631D-37)
Since I don't see any obviously bad caps and one or more bad caps on the psu is likely...should I desolder as many caps from the psu as I can and test them with a capacitance meter. Or maybe remove one-half of the capacitors and test with esr meter? I wish there was an easy way to test caps while in circuit.
TV has been on now for ~8-hrs. The heatsinks on the psu must be near 95C, but the caps seem only warm to the touch (~40C). This TV throws-off A LOT of waste heat, albeit I have the brightness at ~90%. I've...Leave a comment:

Re: Quirky 42" Phillips Plasma TV (42PF9631D-37)
The TV turned-on again today...and has been on for ~6-hrs. I think I've figured out the problem. This time while I was powering it on, I was insulting it. Maybe it just needs to be knocked down a peg or two from time-to-time. I haven't tried hitting it yet, but I think there is a line and physical violence would be crossing it.
Yesterday, while the TV was throwing the 6-3 code, I tried to disconnect the audio board as you suggested, capkid. Sorry I didn't mention it before. It didn't seem to do anything....Leave a comment:

Re: Quirky 42" Phillips Plasma TV (42PF9631D-37)
I pulled the power supply out of the tv for a few hours, then reinstalled it. The tv didn't turn-on this time. No video or audio. The LED on the front of the tv is still flashing the 6-3 error code (6 long flashes, followed by 3 short flashes). I heard 1 click come from the right side of the power supply when I plugged the tv in, and another click when I tried to power it on.
According to the service manual, (if I'm reading it right, which is unlikely), my tv is indicating Error 63:

Re: Quirky 42" Phillips Plasma TV (42PF9631D-37)
I'm not skilled in electronics. I had to look-up what ESR and FET might mean. I don't have a ESR meter. Even if I did, I wouldn't know what to look for. I don't know how to check the FETs for shorts.
The only meter I have is a multimeter for around-the-house and automotive use.
I bought the tv in the hopes that there would be some obviously bad caps as suggested above by freakaftr8 and that it would be a simple matter of swapping them out....Leave a comment:

Re: Quirky 42" Phillips Plasma TV (42PF9631D-37)
I powered-off the TV, and then powered-it back on. There is audio, but no video (black screen). There are no flashing LED warnings. The LED on the front of the TV is on steadily. I didn't hear any clicking coming from the psu board this time.
I tried cycling the power for a second time. Now there's no video OR audio. Still no flashing LED warnings. The LED on the front of the panel is just on steadily. I also didn't hear any clicking coming from the psu board.
I tried unplugging the TV. When I unplugged...Leave a comment:

Re: Quirky 42" Phillips Plasma TV (42PF9631D-37)
The TV powered-on!
Since I took the power supply board out, I reinstalled it and tried to power-on the TV for sh!ts and giggles. It powered-on with no problems. There was some clicking coming from the power supply during start-up, but there are no more LED flash warnings.
I'm not an AV geek, but the picture and audio quality seem to be GREAT. No pixels out or other apparent serious problems.
Now that the TV has finally powered-on, I'm afraid to turn it off until I find out what the...Leave a comment:

Re: Quirky 42" Phillips Plasma TV (42PF9631D-37)
Picked-up the tv today. Was in garage, had not been powered-on in months. We took it inside, but it would not power-on. Instead the led on the front of the tv blinked 6x slow, then 3x fast. I brought it home, took off the back access panel, took some pictures, then tried to power it on. Now, the led on the front of the tv blinks 7 times slowly and that's it. In addition to this, there is an led on the power supply board that blinks 3 times slowly.
I can't find any obviously faulty capacitors on the power supply...Last edited by FlyingHigh85; 11-07-2013, 01:41 PM.Leave a comment:

Re: Quirky 42" Phillips Plasma TV (42PF9631D-37)
Like I said, I've never done work on a circuit board. The soldering iron that I have for around-the-house use is a 45W Craftsman that advertises a maximum tip temperature of 950F (510C). It is not temp-controlled. I'm afraid this is too hot and I might damage the board. I have a few different tips. Would I be better-off using a pencil tip instead of a chisel tip as suggested in the recapping faq? Also, is it necessary to wear an anti-static wristband in this case?Leave a comment:

Re: Quirky 42" Phillips Plasma TV (42PF9631D-37)
Thanks for the input. That'll be the first thing I check when he gets around to showing the tv to me. Worst case scenario, if I damage the board when trying to replace the caps, I think a new ps costs ~$60. I'll likely buy the new caps from here, but what about a local shop, like RadioShack? There's a store right down the street (don't have to wait for shipping).Leave a comment:

Quirky 42" Phillips Plasma TV (42PF9631D-37)
A neighbor is selling a 42" plasma tv that isn't working properly. He says that the tv turns-on and works fine when it is cool, but once it has been turned-on and then shut-off, it takes DAYS to turn back on. Also, when he turns it off, he also has to unplug the tv because LEDs start flashing on the tv.
He hasn't had a chance to show me the tv yet, but I suspect the problem is bad capacitors. I have done a bit of soldering/desoldering, but never on a circuit board, but after reading some how-tos on this site (and others) I think I have all the tools and skills to manage it.... -
