CDTV infra-red mouse problem [SOLVED]

[tokyoracer]

I recently acquired an infra-red CDTV mouse, but I have a problem.

It moves only horizontally (left or right), but not vertically (up or down). Buttons seem to work though.

I changed batteries, nothing. I changed even the trackball but still nothing. I cleaned it, nothing.

Any suggestions?

Have you opened it up to see if the sensors (where them spoked wheels are) are positioned correctly? If so and still nothing then they may need to be replaced but I wouldn't know where to find such spares, but maybe if an A500 mouse is compatible it could be cannibalised?

They seem to be in the right place, but I don't understand. How they can be moved? Are they fixed in place right?

Sometimes in some mice the sensors are solderd on un-flush from the board so it has a little play. I assume yours are totally fixed in that position?

How I can check that? I have to open the mouse?

Fraid so, may help cleaning the insides of it too (like the sensors and them spoked wheels I was on about before.

I opened it. I cleaned it (although was nothing dust inside), and now it works! I didn't touch anything... Anyway... Happy end... Thanks...

Super! Enjoy your mouse, I have been looking for one of them myself for a while now.
