I have the same problem here, this IC is shorted, is made by International Rectifier, it must be a inverter IC the number printed should be a ghost number because I can’t find it, maybe BOSE ask IR to put a nonexistent number to block people fix it, the number by the way is P HA1M1 here is a photo also, if someone ifr7103 about which other number works here let me know datasheft.
