Scanner motor runs on but no initialisation

Threaded View

I have a diamond view scanner that has just decided to play silly

I'm probably better off buying a new one (it's only about 2 years old
tho!!) but I thought I'd ask in case anyone had something similar and
it's a simple fix.

It won't start up or initialise properly.

When powered up, the tube lights up the motor starts up and tries to
home the head. The head bottoms out but the motor doesn't stop, it
keeps chattering away until it gives up then tries to do it again a
few minutes later.

I've looked for a microswitch or similar but can't find one so I'm
guessing that load on the motor is sensed and that's how it decides to
stop and or change direction.

Is this sensing done in the motor or does the  circuit board do this?
If the motor, I might consider replacing that but if it's the board
then I'm tipping it's easier cheaper and quicker to simply buy another

Any thoughts?
