Re: KLH Bassbite II Subwoofer works, satellite speaker channels do not
At the very least it will rule it out, but I think it's bad for the following reasons:
The sub woofer works fine. This tells me that the other IC I saw on the power board probably controls the subwoofer only.
The power supply/subwoofer board shows no signs of burned components
The IC is in the same circuit as at least one of the failed 22uf capacitors. Judging from the pinout, the failed 22uf was on the trace that feeds power to the IC.
I've replaced every component in the burned area except the diodes which seem to be fine, and the IC.
And finally the IC has obviously seen some heat as some of the lettering was burned off, and it took holding it up to the light to read the part number.
I'm starting to think that whoever owned this sub last blew his satellite speakers. This caused the glue to cook on the parts of the board and likely killed the amplifier IC.
