Help - my Panasonic Plasma died!

post #1 of 9
Thread Starter 
Model# is TH-42PZ700U
Serial is PG71980420

I have the 7 blink error code.

History:

-purchased fall 2007
-in May 2008,set wouldn't turn on one day, had 7-blinking light error code
-Frys serviced it for me
-in August 2008, moved from Seattle to Toronto
-now, same stupid error code suddenly appears

So I'm not covered by the original Panasonic warranty anymore nor am I covered by Fry's. I'm kinda screwed. Panasonic had a local service place quote me a $680+tax estimate for the fix. I'm currently vastly under-employed and there's no way in hell I can afford this.

I've read online that the 7-blink error code is something to do with a faulty power regulation board. Panasonic already refused to tell me the board # and just sell it directly to me. I'm wondering if I can find the parts I need on ebay or from a less finicky service center and do the repairs myself.

I'm a computer/electronics technician so this sort of thing really is no biggy for me. I just need to know which parts to replace and preferably find a service manual. Can anyone help?

Ok from another thread I've discovered that the issue is with one of these three boards:

SU / SD / SS

Which correspond to

SCAN DRIVE SD BOARD TNPA4253 from PANASONIC TH-42PZ700U
SCAN DRIVE SU BOARD TNPA4252 from PANASONIC TH-42PZ700U
XSUS SS BOARD TNPA4251 from PANASONIC TH-42PZ700U

I think I've answered my own question. So..anyone know where I can get these for cheap? And more importantly, since I've had this problem twice now with the same damned set, I'm wondering if there's a class-action somewhere about Panasonic selling obviously faulty kit?

I had the same issue and replacing the faulty board did not fix my problem. It turns out the entire panel itself had to be replaced. Rather than paying for a new panel, which was more than what I paid for the TV itself, I called up my credit card company and was able to use their extended warranty program. Basically they paid me a check for the price of the TV since the repair costs were so high.. Pretty sweet.

Unfortunately, my credit card doesn't have that (freaking awesome) feature. I think I may well be screwed. Especially if you're right and the whole panel needs replacing, not just one or more of the three boards.

Lucky you! Now you have excuse to get the lastest plasma. Just kidding. I feel your pains.

I am sorry for your loss, I really am. Perhaps there is a way that it can be brought back to life, but it is possible that those repairs would cost as much as a new TV. I agree with SimpleHT It may be time for a new panel. On a side note you MAY want to consider and extended waranty. Just a thought.

EBAY, has them. Or had them .......just google your part numbers.

Have you tried calling some local repair shops and asking for a repair estimate? Places around me charge ~ $20 to eval the set & give repair estimate. Chances are just a board needs to be replaced unless Fry's replaced the entire panel last time you had it serviced under warranty. The general rule of thumb is fix if repair cost is < 50% of replace cost.

EDIT: Try calling non factory authorized shops or have them look at the set before providing a repair estimate.

Out of interest, which credit card do you carry that offers this extended warranty ? Any more info you can give us on this ?
