I sent my amp to Pyle because the main reason was the right side channel wasn't working. They replaced the noisy fan and resoldered a connection. Pyle did a great repair on my amplifier except for one thing. Using the remote control, the volume still doesn't work. I can still adjust the volume with the main volume control, but I wished they had fixed this problem too. I wrote them back to tell them about the volume not working through the remote but I still haven't heard back from them yet. It could possibly be the remote itself. Not sure.
