IPM Question

[mmartell]

Working on an LG 60PC1D atm with a shorted zsus sus ipm. Have not yet removed part. The sticker on the heatsink reads 4921QP1046B.

Does anyone know which YPPD and STK this part crosses to ? Seems there should be an ipm matrix somewhere.

It looks like http://www.diytrade.com/china/pd/117...21QP1046A.html

I read somewhere the version needed to be matched(maybe Coppell TV) with the other IPM eg. B with B , C with C etc

maybe remove it and have a look or crack it open? Or get a set and replace both. I think the other will be J016 - I'm guessing though

Is there no white sticker on the eadge of the IPM itself?

Re: IPM Question

Don't see any sticker yet except what's on the heatsink. And the other one does have a different pin configuration so you could be right about that one.

So I shouldn't go trying to find a J015E or other which might also be compatible then. Thanks for the input I wouldn't have known that.

suggests replacing as a pair

Re: IPM Question

Did a search and found this about mixing c with B

Since we sell J015C and not J15B and since the mix-up of a J015C and J016B is deadly, my first guess was that they had installed J015C as a replacement of J015B and, sure enough, it would have lasted a very short time.
I wrote back explaining that we pay premium for our J015C components (and we really do!) and that we haven't had a defective one in a very long time (and indeed we haven't!) and that perhaps they confused J015B with J015C. This is a common mistake which is the reason why in the listing for the YPPD-J015C sale we have multiple warnings about the need to use C versions for both IPM modules on the sustain board.

Re: IPM Question

That's some good info tw. I will replace with a j015b, no point in replacing both as finding new ones is next to impossible so why replace used with used.

Also there is a scratch on the screen so I've offered to my eight year old son for gaming. He doesn't want. Can you believe that ? Admittedly he's become spoiled by gaming on a much larger front projector but it's time for me to have that back.
