We use several of these low priced uniss and reckon for a small theatre they are a good bang for buck. But one of our units recently developed a problem. When going through start up or when manaually operating Pan the head only goes around 2/3 of a full curcle and then the thing graunches like mad. With power off we can turn it through its full 540 deg. But once the power applies we get this grinding sound as the unit tries to force the head beyond a certian point. It sounds very much to be a mechanical problem. We have tried factory reset a couple of times and opened the unit to see if there was any obvious breakage or obstruction.
