Got a Onkyo TX-NR807 MDC with a bad HDMI board. There was a known issue with the soldering on the DTS chip and the factory extended the warranty for quite a while. Unfortunately, that extended warranty is past. The owner had asked me to see what I could do with it, and I was able to reflow that 320 pad BGA with a heat gun, and the repair lasted about 3 months. Started failing again, and additional attempted repair has been futile.

So I am looking for a used, functional HDMI board. The manual calls it
BAHDM-0132-1B, the actual label on the board is BCHDM-0132.

Anyone have any leads on where I might find a good one (for a reasonable price)?

Know someone who can reball it? I inquired at a board repair facility nearby but they don't do consumer devices. They didn't give me any kind of price, but left me with the impression it wouldn't be cheap. Bake the board for 24 hours to remove any moisture. Remove the part, clean the part and pads. Inspect the pads and runs, reball the part, reflow it to the board. Finally x-ray the assembly to check that all 320 connections had been made with no shorts.

I’ve repaired a few hdmi boards and they away crap out over a short time. Heat is what kills them. I always install a small fan over the boards to help with them
I’ll look in my parts boxes and see if I have any of them
Do you know of any other models the would fit and work in its place ?
