A2000 mouse port dead

[dbrads]

Hi All,

 My A2000 mouse port has died, the pins are fine and I have tried 2 different mice that are OK on my A1200 so it must be something on the MB.

Any suggestions?

Thanks for the replies guys,

I have replaced the CIA chip but no joy, I have a rev6.0 board and can not see a "green fuse" so it must be something else.

 I will e-check the pins and solder.

  PS, The buttons work :-?

I have looked at the mother board, cant find a fuse F1.

Looking at the schematic the fuse is for both ports but the joystick is OK so it cant be that, the port control chip (U202) must be Ok too.

What are the small blue items behind the ports, could one of these be the problem?

JimS, Well flippin ek!

 Didn't look there, yes I have a fuse, I will test it tomorrow.
If it is defective where can I get a replacement (I think I am skilled emogh to replace it myself.

Hellcoder, thanks for the info about swapping mouse ports program, I have downloaded it already! Port Switch by Steve Sloggert.

Thanks for all the replies, good to know there are so many helpful people out there.

 Thanks for the help, I think i will try the inline fuse holder idea, we have a Radio Shack here so I will try there first.

  Keep the faith!

What rating fuses did you use? I will have a go at the same solution.

I have soldered a 4 amp glass fuse to the F1 position and it works!!!
