Re: Panasonic Plasma - 10 red blinks TH-P58VT20A
Just letting everyone know I received the SS board back with all the failed IGBTs and what not replaced and she's back up and running.
Thanks to everyone who helped out. Learning how to diagnose the problem and the successful outcome was quite an enjoyable experience.

Re: Panasonic Plasma - 10 red blinks TH-P58VT20A
Ok. I found a short at SS11 and across most of the IGBT's of the SS board.
I've also been told that IGBT's can go 'pop' without showing any signs of failure.
So with the SC and SS boards out I go from a 10 blink to a 6 blink code.
The 6 blink code is due to Open connection between connector D20 on the D board
and SC20 on the SC board. (the ribbon cable)
With the SC board in but the SS board out it powered up green for 20 seconds then came back with a 10 blink code.
There is...Last edited by HDS; 01-24-2017, 07:11 AM.Leave a comment:

Re: Panasonic Plasma - 10 red blinks TH-P58VT20A
So I've had the SC board looked at and it's fine.
So I'm confused.
So I went through the flowcart again and removed the S11 and S33 plugs from the SS board (with the SC board still out) and got 6 blinks.
Still have to test the SS board for a short but after finding a short on the SC board without there being one I don't want to make the same mistake.
Is it possible the SC board showed a short at SC2 because its ribbon was still plugged in?Leave a comment:

Thanks for the tip. Time to get the ball rolling. Footy season is fast approaching....Leave a comment:

Yeah I found out even more than that. The 9 boards in stock was a dead give away

OK CraDeal.com is a no go. Dodgy prick.

Re: Panasonic Plasma - 10 red blinks TH-P58VT20A
Yeah. She made a almighty pop.
No way of knowing for sure which components are toast or not without the proper equipment and testing.
I found this link

States that these are new boards. I find that hard to believe as they list 9 in stock and a a really good price it seems to good to be true.
There's is listed as TNPA5175AB, my board has TNPA5175AG.
The listed part...Leave a comment:

Thanks for the link.
After looking at a youtube video on how to replace the components with a service kit I'm pretty sure that's not for me.
Time to find a second hand board or get mine repaired.
Anyone from Australia that can recommend a repairer please let me know.
Thanks and a Merry Xmas to you all....Leave a comment:

Re: Panasonic Plasma - 10 red blinks TH-P58VT20A
OK so my board is a TNPA5175 (SS is a TNPA5176)
The SC2 plug comes as a short.
I found several of the IGBT's to have a short between their source and gate pins but after reading about them they normally short between their drain and gate pins?
I tried the method of charging the gate pin then testing the drain but still couldn't find a short through any of the IGBT's drain pins and their source pins.
You guys were right about the SC board and saved me a heap of time. Many thanks,...Last edited by HDS; 12-20-2016, 06:24 AM.Leave a comment:

Re: Panasonic Plasma - 10 red blinks TH-P58VT20A
Thanks for your replies.
I've read a few nights worth of stuff on the 10 blinks and found this place to have the best answers and advice.
I didn't realise a tiny transistor could make a sound like that but after looking up what they do and the loads they carry it makes sense.
I'll check the part number on my SC board and pull it out for inspection.
Thanks SteveLeave a comment:

Panasonic Plasma - 10 red blinks TH-P58VT20A
Well it looks like I'm not the only owner of a dead Pano plasma.
Mine went 'pop'
I was sure it was something power related as it was a decent pop when turning the set on. It flashed white, something went pop then it went blank and started with the 10 blinks. It does this once the cord is plugged into an outlet not when you try to turn the TV on when on stand by.
So I thought I'd find a capacitor is a bad way but nothing is overly evident to my problem. No obviously blown caps, no discharge, no burnt sections on any board.
So I took a pick... -

Well I'm here to fix a Pano plasma I bought that lasted two weeks then went pop.
