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

Where should I be finding 15v tp ? Vscan did seem low to me. when the screen powers up the power supply gets loud like inverter under stress so I don't leave it on more than a few seconds last time the 16n55g blew this is my 3rd set

Also I personally didn't replace the TEA1611T plus caps on MC201 and MC301, it was done by a student 3 quarters behind me that could not fix it, this is how I acquired the set
free

are mc201 mc301 the same moduels could the previous repairer put them in wrong would this cause your fault? just thinking aloud here i dont know what these moduels are for.

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

thanks didn't have SM for schematic this one should be much easier than the "panny tnpa4782 issues" will test shortly

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

They have slightly different part #s so I presume it's possible to put them the wrong way around and have it not work.

The modules generate the drive waveforms for the 16N55G's.

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.

I have the 15.9 @ connector p6 seems little high

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

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

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

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

[forefrazier]

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.

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

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

[forefrazier]

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

Yes. I believe so.

[vinceroger69]

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

Yes. I believe so.

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.

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

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

Was it this place?

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.

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.
