Audioguy564 Posted March 18, 2009 Report Share Posted March 18, 2009 it could be the output chip that is fried. on some units the RCA's are powered from that chip so those wont have signal either.

raytard Posted March 18, 2009 Report Share Posted March 18, 2009 yea, they all have little 200watt max mosfet amps in them, could just be that you fried a fet in there, so the input side/screen all works but the output doesnt work kinda rare to happen, but....the h/u is basically screwed, unless its a really nice h/u, its time to get a new one, its not really worth fixing imho Build: http://www.stevemeadedesigns.com/board/ind...hl=avalon+build monster/rockford/kicker/stinger cables, pioneer source, jbl highs/amps, kinetik/shuriken batts, iraggi alt, dei security, dc subs(atleast for now) Team DC Link to comment Share on other sites More sharing options...

Audioguy564 Posted March 18, 2009 Report Share Posted March 18, 2009 RCA's don't work either, if they do then you just use an external amplifier.
