Friends, This is the first karaoke we have taken in. (May be my last!) Took it only because it belongs to a school I do work for. Can not find a model number anywhere. This unit resembles a floor speaker about 18 inches square and two feet high, with castors. The disk does not spin at all, except when power is turned on. Then it "bumps" a 10-20 degrees. I have cleaned the lens. With no disk in, the lens attempts to focus, moves on the rails, tries to focus again, and repeats. I cannot see if the laser turns on. The school tells me the unit was purchased from Radio Shack. The first unit they bought was replaced by RS because, in her words, "It could not be repaired, and nobody in the VocoPro company in Industry, California spoke English. Any suggestions?
