Help! I have a SONY MHC-EX9AV hi-fi midi-system?

I have the same midi-system and I had the exact same problem a few years ago. I took it to a repair service and there they changed a condensator and that did it. It was found very quickly and it was actually very cheap!
You have to bring them the tuner as well as the amplifier and also the connection cable, otherwise they can't do anything with it. Repair in this case is certainly worth the effort!

Since yesterday I have a new problem with the Sony MHC-EX9AV set: the double cassette deck suddenly isn't able to play tapes anymore (neither left nor right). The mechanism still moves the head to the tape surface but it can't seem to get the tape moving. Then the head refuses to go back down and consequently the cassette is stuck in the device. I only played tapes on this machine every once in a while, I can not imagine the heads are due for renewal yet. As I said this problem started to occur in both deck A and B at the same time! As if the engine can't pull it anymore. So today I went to the same repair service that I went to some years ago, but now they don't repair it on the spot anymore. Instead they send it to a central repair station elsewhere and in my case, they refused to accept my cassette deck (with amplifier) for repair. They said it wouldn't pay off and they may be right, but I'm very dissapointed. I opened up the thing myself and I managed to unjam the door and remove the cassette, but I don't now how to repair it - too complicated for me. Does anyone have a hint?

Well, no need to worry now... i have it sorted!
Thanks to ROMKO answering another question ( faded display on sony...) I now know what's wrong, I had a look at the lamp and I'll definately let the pro's do it!
As for my little shorting problem... thank goodness for circuit protection!! the funny thing was that the fuse had only 90% blown so it still had some output albeit very limited. At least now the unit is fine and dandy, yey! :-)
