unplug the receiver, Everything- speakers, input/outputs. The only cord to the device left should be the power cord. Power up the receiver, set the tuner on a strong station. check sound quality with headphones only. If that was ok, now pick one speaker to test all channels with. Follow the procedure above with the speaker. check each output channel with the tuner as a source using the one speaker. Good Luck!
The problem could be in the output from your receiver to the amp or in the amp itself.
First check to see if the amp powers up. If it doesn't, check the main power fuse (usually located under the hood near the battery). Also check the power and ground connections on both ends.
If the main fuse checks OK, check both onboard fuses. There's 2 35A fuses on the far right.
If the amp powers up OK and the onboard fuses are not defective, it's possibly the output from your receiver or line output converter. Replace the RCA cables with a known good pair. If there's still no sound, I'd suspect that the amp itself is defective.
did the left channel work when u switched speakers, if so then the left speaker or wiring is a fault.if not then the output circuits on the amp are blown or the fuse is blown some amps have internal fuses in the output to protect the output transistors. unplug the power cord and take the cover off, look to see if u can find any fuses and check these for continuity u can hold these up to the light and u should see a fine filiment in one piece and not broken. these fuses sometimes blow just from age and use at high volume like a regular light bulb.If the fuse is blown replace with the same value else the output transistors will need to be replaced most likley along with the drivers.
Usually the outputs are not fused, but you can go thur speaker white noise test and see if that works first. If it does, then outputs are probably fine, IF not then the output transistors are most likely bad. Let me know and we can try some other things thur live chat if you would like. Good luck Guru Jay
I have experienced a similar problem with my Sony STR-GX57ES and took it to a certified tech only to find it needed the power supply replaced. I opted to hunt down a compatible power supply but have been unsucessful thus far. That being said I picked up an STR-D665 for next to nothing and found the power supplies to be quite different (you would hope so any, with the ES meaning Elivated Standard and all) but with the D665 working flawlessly I'd rather have something working than nothing. Good luck!
