Good luck.

Philip,
Thanks for your suggestion
As noted I did pull apart the HC and clean the silicon tactile push button pad and PC board. Looked fine no mould or dirt or bugs.
Each button has 2 copper contact points on the board so design wise it’s not the most reliable design as it relies on equal finger touch pressure on the silicon button to make clean contact on both contact points. But in saying that I’ve used these HC on EQ and AZ scopes for years without failure.
The strange thing the AZ and Alt motors are responsive and work fine it’s just the change in Rate when you drive the scope in Az, it stays at Rate 9 or fast
Hoping it’s just the HC and not the Az motor board ?
Cheers
Martin
