Most likely a burnt out PAL decoder for the Dec? channel ¨C you need to program it of course. ? From: [email protected] <[email protected]> On Behalf Of Michael Herman ? Hi gang! ? I received John's questionable G2 mini board, to test it out.?? ? Symptoms: ? It boots up fine. ? It slews to an Align Bright Star target fine. ? If you press the RA diamond East West button it slews RA fine. ? If you let it run Sidereal rate it tracks fine. ? If you press the DEC diamond East West button, the DEC motor runs away!? ? This is repeatable. ? John got a new board from.the factory and his system is fixed...it is definitely a problem with this board, not the cables, motors or handset.?? ? I'm unsure what to do to try and repair this board...John did try to resolder his DEC socket.?? ? Any suggestions from the above clues? ? Very best, Michael ? ? ? ? ?
