my beogram CD 50 had gone mad recently . whenever i open the cd tray , it close back right at once . now changing cd became a challenge to me . i know a little electronic and have opened it up before , can i repair it myself ? any technical advise ? thanks in advance .

I recently had a problem with my CD50 tray, in that when I replaced the tray drive belt, I inadvertantly messed up the alignment of one of the cams in the mechanism that tells the CD mechanism when the tray is closed. Sounds like you might have a problem in a similar area, but I expect Martin (Dillen) will be able to advise further.
