I am thinking something else is up here besides broken heads (like I am doing something else wrong) since seeing as this is >80% failure, all at the same time.
The heads pop up normally, they just don't move/rotate.
As far as troubleshooting, I've tried the following
- rotating the heads one click to the right
- adjusting the degree of rotation knob (the one with the +/-, not the house icon.
- replacing two of the heads (which now work flawlessly
Any input on what might be wrong/how to fix?
