Durabrand model cd-1493...cd won't play
A friend of mine has one of these, and the same thing happened. Toss in a CD, and the unit reads it, but doesn't play it. Looking at the CD components, all appears to be well, and I was even able to trick the unit into turning on using a paper clip to hold down the "lid closed" switch.
What I found the issue to be was with the lack of downward or clamping pressure the CD was getting with the lid closed. If you notice, with the lid open, there is a round part that "floats" and serves two purposes...one is to align the CD and keep it steady, and the other is to grip it, as the CD's do not snap into the lower centering piece, but rather just sit on it.
I solved the problem by placing a rubber o-ring on it, The one I used is about 1/16" (1mm +/-) and about 1 inch (25mm) diameter. I used some rubber cement to attach it to the top piece. I'm not sure how long this will hold, but it's worth a shot. I figure keeping a CD in the tray will help keep the ring in place as well.
