Default JL AUDIO 500/5 (dont worry, not in-car related)

ok, so i tried every trouble shooting test there was, and have determined there is something wrong with my amplifier.

the subwoofer channel works., and one of the rear channels work, the other three will not work.

so i cracked it open. trying to figure out what hapened.

i suspect the most likely cause is the outputs are fried. but i dont understand how 3 out of 4 channels refuse to operate.

i know what blown outputs sound liek, distorted mos-fet noise, and its in no way in accordance with the music.

the sound i get out of the 3 bad channels is a hardly audible treble that plays along with the song that is on.

anything i can try? i see indivdual "BIAS" jumper pins for each channel. anyone know what these can do?

i really dont want to send this amp to the distributor for new outputs.

THANKS
