I recently purchased a second hand ETX 80 which has a fault. This is a bit long winded so hopefully I will get the problem across.
When I switch on the Autostar I get the copyright screen coming up. I get no sun warning or Getting Started screen and no Beep at all. When the handbox starts it says "initialising" the word "time" flashes up, the cursor goes round a couple of times and looking straight on at the display it is unreadable as it is too bright (high contrast, which I cannot adjust?). It the display on the handset is tilted either up or down (still looking straight at it) the screen can be read, albeit with some difficulty. Some of the menus seem to work, but when I try to do a reset, nothing resets and it remains the same. The slew controls - If I press right the mount turns right, If I press left the mount still goes right and the same with up and down - press up the telescope moves up and down the telescope still goes up - in short the telescope will not move down or left when pressing the appropriate keys. There are several other things in the menus that have no effect e.g. changing the sun warning to on or off, turning the beep on or off and turning Getting Started on or off. There are probably a lot of other faults which I cannot check as I have been unable to use the Handbox properly or familiarise myself with it.
The telescope is otherwise in really good condition and I have managed to view Jupiter and a few other things without the aid of GoTo. I have tried various things but nothing seems to work. Can anybody suggest where the problem may lie, faulty Autostar Handbox or perhaps more concerning some other electrical glitch within the system. I have cleaned the contacts on the hbx plug and am using fresh batteries.
I am in the UK . I am at a complete loss as to where to go next.
Any help or advice will be gratefully received. If required I can maybe upload a couple of pictures showing the display.
