Pioneer SX-550 Repair II - Sound Distortion
This is the second repair video for a Pioneer SX-550 receiver. It wasn't an easy job for repairing this unit because I couldn't find the problem by using signal tracing tool. By comparing the working voltage with the schematic, I found the sound distortion was came from the defective power transistor. I hope this video will help other DIY fans when dealing with the sound distortion issue.
