I hope i am on the right place to find a solution for my problem
I Have a Merlin/Orion (Not sure wich model because there is no model number or brand on the head and the hand controller with 9 buttons (GUIDE,SLOW,FAST,LEFT,RIGHT,UP,DOWN,SET and GO)
What i can say is that in the head the board is labeled as SYNTA MC0001 Rev. D, to start explaining my problem first of all i did not buy the head for panoramic shooting, i buyed i used Video Crane that had that Merlin as Motorized Pan Tilt Head, first i didnt know that the head is made for panoramic shooting, no mind.
Everething worked well for about 1 year and before a few days when i turn the head on, my hand controller is not working just blinkink SET and GO buttons, and the head is not reacting to any function.
