Hi there!
I'm trying to fix a garage door opener with a Moore-O-Matic Delta-3 remote receiver. The board looks good except for a little TO-92 that appears to have deposited some soot on a neighboring capacitor. The TO-92 is labeled "SL 28884 F8307" -- which I haven't been able to cross-reference anywhere. Anyone have any ideas as to what this might be and whether it's still available? Replacement remote receivers are $30-ish with shipping, so it's not the end of the world if I have to replace the unit.
Thanks in advance!
