I have a optimus 400 watt amp. Only channel one and channel two produce sound and channels three and four dont produce any sound. Please tell me what components i need to check or what i need to do to fix this?

I'd start with the diodes, transistors, FETs, resistors, coils, fuses and capacitors. Wink
