Thanks for your reply! I’m still wondering about some things, though.
The radio used several other Panasonic components, so I just used the Panasonic layout with (from L to R) 1: Vout, 2: Gnd, 3: Vcc. I never found a match either, but all of their receivers seemed to have the same pin orientation.
I tested it while it was still in the board, do you think that will mess up the results and that I would definitely need to take it out to test it?
Assuming it could still be tested while in the board, when I hooked it up to an LED, the LED was constantly lit. Would that be a symptom of it being fried? Or just a sign that I hooked it up wrong?
I guess the board could be messing up the results too…
At this point, I did probably ruin it in the process and will need to replace it. If I can’t find the exact match, will I most likely have to replace the IR emitter in the remote too in order for them to match?
PS- That Rohm that you found does look a lot closer to what I have than any of the Panasonics I looked at. Does Rohm have a standard marking on it to at least narrow it down to brand?
