I have a QHY9 colour camera with a QHYCCD adapter type DC-102.
During normal operation last night the TEC appeared to disconnect and could not be restored. The normal -15v,+15v +5v and Fan red leds on the Adapter remained alight but the TEC led was off. I turned the camera off and disconnected the DC-102. I then reconnected the camera and DC-102 following the safe connection procedure in the QHY9 User's Guide. All cables were checked as well as the 12volt supply to the Adapter - all appeared normal. The camera now works normally but without TEC cooling.
It looks like an internal failure in the DC-201 Adapter.
I have an old DC-101 adapter that I used with my previous QHY8 camera. Would this be compatible with the QHY9 camera?
Any suggestions?

Thanks for your suggestions. I contacted Theo and he was very prompt and helpful in the possible supply of spare parts for my QHY9. However, with further testing I found that the problem was a faulty connection of the TEC cooling controller to its 12 volt power supply. I had made the mistake of having this connection permantly patched up for a prolonged period at my mount. A simple clean with electronic cleaning fluid fixed the problem - lesson learnt!
