Panasonic plasma TH-42PZ80U 2 blink 15v SOS

Re: Panasonic plasma TH-42PZ80U 2 blink 15v SOS

I have a Panasonic which trips after switching on, and as a 2 blink fault code, the +15v detect led is lit, do I assume correct that it is showing the + 15v is missing.

15V detect LED? where's that?

All I can share is with my PZ800 when it had 2 blink it was a tiny cap, the same cap that everyone talks about and in the you tube video on the MC201/301 modules.

From memory I think 10 blink is MC201, 2 is MC301 but if you were going in there to replace the cap on one, I'd do the other if it was still the original.

When you say goes 2 blinks after switching on, the TV never turns on it just 2 blinks? That's what I had.

My favourites are these

I also recommend some solder wick and fresh solder

(You can buy solder from a hardware shop, or a place like RadioShack/Frys.)

You will also need a soldering iron. Ideally one that is temperature regulated - though that may be a big investment for a simple repair like this.

I would recommend removing the small board from the main PSU board, and working on that. Work slowly, there are no awards for fastest repair.

The PSU board is held together with about 40 screws on the back and 8 or so on the front. Then there are about 10 or so plastic clips - it takes a bit of work but the board will come apart - DO NOT FORCE IT, or you can crack the board.

Leave the TV unplugged for at least 1hr before commencing work.

Great thanks Tom. Can I get a reference on where to buy the caps and what kind?

Re: Panasonic plasma TH-42PZ80U 2 blink 15v SOS

I have done 7 of these power supplies (6 x 42", 1 x 46") and none of them needed any more than the capacitors replacing.

wait and see what toms and tw2005 thoughts are too if you want but im my opinion your new board is bad too. I take it you dont want to try to replace the old capacitors on your old psu yourself? How good are you at soldering the points are a little small but the job is doable with patience i have done this repair my self and my sets still working great.

I have no experience with soldering but am a "handy" guy. I could probably do the job but have no tools so was trying to go the easy route.

Would I just need to replace the capacitors on both boards or do I need to replace the IC's also as shown in Norcal715 video on YouTube?

BTW...Thank you all for the help so far!

If you paid by CC/PayPal then I'd first try negotiating with seller to send board back. Clearly faulty board. If that fails then file chargeback or complaint with PayPal.

Was it this place?

http://panasonic.factoryoutletstore....er-Supply.html

If so i very much doubt Panasonic has anything to do with it, by their own website they're "independent retailer of consumer products"

I'd put a ? on whether it is in fact Brand New.

Yes. That is the place. I understood when I bought the board that it was not actually coming from Panasonic but this was the only place that said the board was new. Now that I have done more research, I probably should have either sent my board to someone to fix or tried to do the repair myself.

Or, in the worst case, there are sellers on eBay doing this repair service for less than $100.

sounds like you new board is faulty too do they offer a return policy?

Re: Panasonic plasma TH-42PZ80U 2 blink 15v SOS

Sorry..meant to say I froze the same IC chip/capacitor at the same location and the TV worked with the NEW board for approx. 30-40 min.

Re: Panasonic plasma TH-42PZ80U 2 blink 15v SOS

Yes...I froze the same board and TV came on and worked for about 30-40 min until it shut down again.

[tom66]

Re: Panasonic plasma TH-42PZ80U 2 blink 15v SOS

So on your NEW board, does freezing it make any difference?

Re: Panasonic plasma TH-42PZ80U 2 blink 15v SOS

Brand new here with the same problem on my TH-C50FD18. Did not want to risk soldering parts so bought a new PS board from Panasonic Factory Outlet Store online. Swapped out the entire board and I still have the same 2 blink issue. Another bad board or something else causing the problem? I also do not know which location is MC201 vs. MC301? When testing the boards with refrigerant to cool, the one on the left seems to be the problem. Any help is appreciated as I just paid a pretty penny for a "new" board and didn't fix a thing. Thank you!

Re: Panasonic plasma TH-42PZ80U 2 blink 15v SOS

Mine gave 15.7V (no blinks); that sounds fine to me.

Re: Panasonic plasma TH-42PZ80U 2 blink 15v SOS

I have the 15.9 @ connector p6 seems little high

Re: Panasonic plasma TH-42PZ80U 2 blink 15v SOS

Unknown didn't even think they would have put them in wrong the boards were removed to do the repairs. Just looked there the same parts but possibly the ic are installed wrong? I have done 3 or 4 of these Panny's with 10 & 2 blinks really easy usually.
