Re: Panasonic TC-P42GT25
I do not have one of those potentiometers. With that said how can I test other boards to make sure they are working so i just order SC and not waste money on just that board if it doesn't work?

This appears to be a video of someone using a very similar multimeter... looks just like mine.

Re: Panasonic TC-P42GT25
Is this how I should be measuring SC2?

Again I get about 315.. which is close to your 300 number you were saying.
This changes nothing. Still SOS1 or SOS10 if I hold down power button.
Not sure how to test the IGBT's but I found your thread which helps locate them... any tips?

Re: Panasonic TC-P42GT25
What is the resistance supposed to be?
Not sure where to go next. Is there any possibility its not the SC board? If its the SC board should I just try to replace it? How much are these things anyway?

Re: Panasonic TC-P42GT25
Ok here are the pictures requested. All different readings depending on the setting used ranging from 200 to 2000k.

Re: Panasonic TC-P42GT25
The guide I used was posted by you in another thread back in July or so. I can't seem to locate it anymore. It said to do a few things and I said "Hey, that looks like mine on the same board, so lets see what happens". It then proceeded to say to unscrew some things and I did not go as far as that yet.
As far as reconnecting SC2...
Without it connected I get about 314 on a 2000 setting, 192 again on a 200 setting.
Upon reconnecting SC2 I'm back to SOS1, not 4. I'm not sure why I saw 4 at one time...Leave a comment:

Re: Panasonic TC-P42GT25
Yes, sos7 is what I got, assuming I got the ribbons back in correctly. my meter goes 200 to 2000kLast edited by mpj31; 12-16-2013, 02:58 AM.Leave a comment:

Re: Panasonic TC-P42GT25
You want me to connect everything except SC2 and give it a shot?Leave a comment:

Re: Panasonic TC-P42GT25
Hopefully you dont mind me linking to my dropbox so I don't have to readjust the pictures. Here are some high-res shots.
Again when I test resistance as you described with TV off, with the multimeter in the position shown in picture 2, I get a reading of around 193.~.
To confirm what you probably already know this is a 42 inch 3d television purchased around Sep 2010. Lot of money spent on this to see it die in 3 years.

Re: Panasonic TC-P42GT25
Ok I plug everything back in that you had me unplug earlier. Then you want me to test resistance of SC2 while the TV is plugged in and turned on?
I have a multimeter... where does the red end go and where does the black end go. Sorry, learning here...
Edit:
Ok so without turning the TV on and everything still disconnected I did as follows and touched the two metal parts. Shown in pic below is somewhat what I did although the red is not touching in my picture.

Re: Panasonic TC-P42GT25
Ok well I did what you told me by disconnecting everything and we have something to report at least. Not sure what you were looking for, but I ended up getting a steady red LED. What should I try next?

I've never done any electronics repair... most I've ever done is built a PC. I think I understand all this and will try tonight and see what happens. I do have a meter, not sure exactly what to do with it.

Re: Panasonic TC-P42GT25
Sorry to be more specific. The TV does not turn on and I do not get picture, I do however hear a couple clicks as I have always heard, whenever I turn it on, and then the screen remains black. I do get power to the TV. The LCD red power light just blinks. "I turn it on and it has 1 blink... then I hold power and get 10 blinks."
Does that help?Leave a comment:

Panasonic TC-P42GT25
After reading many threads and a lot of Google searching I still cannot find where to start on repairing my Panasonic Plasma, Model TC-P42GT25. I turn it on and it has 1 blink... then I hold power and get 10 blinks.
Best thread I can find similar might be this:

No solution found. Seems as if its probably the A board. Could I then just order an A board on ebay and see how it goes? Doesn't look too outrageously expensive?https://After reading many threads a...ll cannot find
