HI, everyone I'm new to this forum and needing a little help trying find a problem in Hr 3700 receiver. I was checking a transistor out of circuit and mixed two transistor up with one another now I'm not sure which one went to the receiver the number are A928A / A1281. I have done some research and found the value are way different I attached a picture of where it was on the board.

Looks like the power supply section. I'd say 1281 is the more likely one to go there, not sure what you'd want with a 20V rated job like the 928. What's the one next to it?
