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 Part COZBZ0001812
I think the part you are looking for is a BD8693 IGBT driver that is fitted to Panasonic SC/SN boards.this would show a Panasonic part number of COZBZ001920. The other larger IGBT driver COZBZ001936 that are fitted to some boards would be a NJW4840 , Hope this is of help Flocko -
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.Comment

Re: Panasonic Part COZBZ0001812
Please post with model and board numbers in the Tv repair forum,and search for more info on repairs, but also note that there are a lot of fake BD8693 ICs,only use ones that show the same markings as fitted by Panasonic (check photos if buying from eBay)Comment

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...Comment

Re: Panasonic TX-P42U30B with CN board TPNA5349AB
Q501 marked Y3 = CPH5524-TL-E (transistor array) these should be replaced with the IGBT driver IC501 (BD8693) as a pair. You will find full details of how to repair and test this and most other Panasonic SN/SC+SS boards by using the forum search.Comment
