any techs around here? this thing was working fine and now has no output on the RCAs or any of the speaker leads. all of the speaker outputs are shorted to ground. there were two diods next ot eachother, betwwen VCC and ground at the power input. these were all burned up. the meter read them as shorted both ways, then they stated to fall aprt and read open... I desoldered and removed these. the speaker leads are still shorted to ground,eachother..whatever..

is the amp chip bad or is it some other problem? I don't have any schematics, I've never dealt much with car audio. the CD player was mounted in my friend's Blazer wich had an extreem heat problem because th HU was mounted under the vent ducts. the only thing common to the speaker leads seems to be the MOSFET OP-AMP..or what ever it is,....I would like to replace that and the diodes (regular black, not zener) and get that amp, from an electronics supplier or Pioneer themselfs. it's a nice HU I don't see any reason to buy a new one. don't worry, this is just a spare anyways, I have a Skipwood in my car now..KFC-215 or what evr it is..
