DAT Sony DTC-790 problem

[dukasound]

Hi
After a long time I try to use my Sony dat but after switch on and put cassete on display was message CAUTION. After this I cant remove cassete out and none command cant work.
I remove it with manual way, rolling pulley who open a dat's door.
I watch manual and after translating to english (this was on german) I decided can be problem with humidity (for example). One day dat stayed switched on and I used hair fan to slowly dry inside of dat.
This morning I try but it's the same.
Does anyone can help me. What can be problem.
Thanks in advance
Duka

Nobody knows?

Usually the Caution indicator means there is a problem with the transport, so it could be a sticky micro switch, bad sensor, worn belt or hardened grease ect. In my experience, any electonics with a complicated mechanism, if not used in a while, could use a good relube to get it going again. Other than that, I really couldn't say what it can be. Good luck!

A common problem with the Sony D7 was that the grease would harden. Careful clean and regrease sorts it. That's where I'd start!
