Sony MC1600
This mini system was a top buy when i bought it some years back and should have lasted a long time.It was not cheap.
However the CD laser has malfunctioned together with the Cassette deck at about the same time. Is it worth repairing or am i supposed to bin it?? I have found it very difficult to get repairs for stereo systems even though it may only be a belt broken. Whats the opinion of the forum? Any ideas how to troubleshoot? Many thanks Freddy |

I still see the odd one of these. Most of the time they're just about worth
doing, but occasionally, they do get some pig faults on them that defy being worth the time to pin down. If the laser itself is faulty, they're cheap enough and easy enough to replace. Looks like you're in the UK so try Grandata in Wembley ( they have a website ) for a replacement. No account needed, you can just deal with them by phone and credit card. Have you tried cleaning the laser ? ( properly I mean, with a cotton bud and IPA, not a cleaning disc ). This model will often have a dirty laser, which will respond, if not long term, then at least enough to prove the point, to a proper clean. Another common problem, depending on exactly which CD processor board is fitted to the underside of the deck, is the 47uF sm caps. If it's the version of the board with three of these along one edge, they are very common to be faulty. They must only be replaced with similar surface mount types. Standard wire ended electrolytics just don't perform correctly in these positions. You don't indicate how experienced you are at audio service work. If the caps have failed, it's usually by one or more of them leaking. Depending on how long the problem has been left unattended, there will often be damage to nearby pcb vias. These are repairable by patch -around techniques using thin etch revision wire, but it's a tricky job if you're not experienced at working out your patch connection points. You don't say exactly what the problem is with the tape, but in general, they are pretty straightforward decks, if not terribly easy to work on. Hope this helps you to make a decision. Good Luck !
