Channel 1 clip light coming on at 30% gain injecting pink noise at unity gain. No speakers/load connected. Channel 2 is ok get about 75%. E-mailed crown and they would not release schematics. Took main board out and checked almost every channel 1 component out verifying against channel 2. Hard to troubleshoot with out schematics or service manual. Have found no issues but still clipping led comes on. Any ideas / help appreciated.

Disconnected main board from output board a measured same voyages at stabs on main board. In process zapped my self on the heat sinks. Noticed both heat sinks are at same voltages too in reference to case ground. This seems bit odd. Anyway really looks like only 1/2 channel 1 is firing. Probably a simple fix like a 20 cent board fuse I just can’t find it. Sure wish crown would release a schematic! I see at compass.com I can get this main board for $109 with free shipping. Guess if I get no help here that’s what I’ll do.
