Hey guys,
Recently acquired a 42pf9966 for free not working, teardown and research showed an upper Y buffer with 4 out of 6 chips literally blown out. Lower board is physically ok looking. I ordered both, will be here tomorrow.
My concern is, should I replace the sustain main board as well? I'm afraid if I plug these in, and the y main is faulty, I will blow up brand new buffer boards. Is this a valid concern? Or will a short power-on be ok just to test it?
Or is there a better way to test my Y main board?
Thanks,
Dan
