    Mitsubishi M VR700 no audio output

    Sherwood RD-6500 A/V receiver blowing fuses

    Thanks, I will run those tests later and then report back when I figure out if the bridges are faulty. It might not be for several days as I have little time but I will surely report back. In the meantime is will make a test light.

    Sherwood RD-6500 A/V receiver blowing fuses

    Hello, I have this Sherwood receiver and bought it not powering on. When powered up the red light comes on but nothing else. So I took the cover off and noticed the 6a fuse was blown on the power board. So I put another fuse in it and it popped. Then I bought some fuses, disconnected the big...
