Thanks again for your responses! I'll answer in order:

1). Setting the trigger to Auto makes no difference at all

2). With no input and the trigger set to AUTO and timebase set to 0.1s, pressing the RESET button shows a momentary flash of a dot at the LHS of the screen and the orange light stays on for 1 second then goes off. The dot doesn't move from left to right - just flashes on for a fraction of a second and then off.

3). I have checked the potentiometer and it does indeed sweep from zero to 7.5k when measured between the centre and both external legs in turn.

Bizarre!

Cheers

Sean
