Re: Panasonic Part COZBZ0001812
I think Q501 has gone U/S. The 47K emitter resistor has gone O/C. It's a B1HFPFA00001. The waveform on Q401/402 is all wrong. What is the replacement equivalent please?
TV is a Panasonic TX-P42U30B CN board is a TPNA5349AB. Thanks for your support...I am a new to this type of repair...

Re: Panasonic Part COZBZ0001812
Yes that looks right. I miss-typed the Panasonic number, it should of ended 1822 not 1812. Out with the heat gun now I can order replacement/s. Can you live fault-find on these boards...if you can keep them from shutting down....beyond static resistances checks?
Thanks Flocko.Leave a comment:

Panasonic TX-P42U30B with CN board TPNA5349AB
Can anyone please tell where I can get a Panasonic Part COZBZ0001812. The tiny 8 pin SMD has D86 93 NZ printed on the body (possibly 2 characters missing). Its a driver IC for a IGBT on a plasma scan board. Does it have a none Pansonic part (generic) ID? -
Re: Panasonic TX-P42S30B - 6 blinks
Hi Guys. I'm chasing a fault I think I have on the SN Scan recovery H side (6 Flashes). I have replaced Q441, Q421, Q422, Q401 which were short.
I want to replace IC 501 by substitution but what is generic part number? Panasonic part number is COZBZ0001812. The tiny 8 pin SMD has D86 93 NZ printed (possibly 2 characters missing).
Is it possible to scope any of the waveforms or part run the SN board (no SC IGBT's or diodes) with some current limiting?Leave a comment:
