HEQ5 Help - Lost Power?

[Twiggles]

Hello, long time since I posted here!

Finally dug my telescope and mount out (200PDS and HEQ5), intiially everything was going fine, then all of a sudden the handset shut off. Power LED is on but no motor sounds and no lights or display on handset. If I plug in the USB and connect to PC the handset will light up and I can slew the scope but autoguiding isn't working.

Any ideas??

If the mount powers up through the handset, and responds just fine, but when powered directly everything is dead then this suggest the fault is either in the connection between the small interface board where all the connections are made and the main board, or the main board protection diode has blown, or the two large capacitors have failed (a common issue).  

If you are confident in soldering then it might be worth looking at these parts first.  If not, drop me a PM and I'll take a look.  Can't promise anything, but the current board in my HEQ5 had a similar issue and replacing the capacitors brought it back to life
