Amiga 500 Joystick problem

[Nerfherder]

Hello all!
    Just wondering if anyone has run into this little problem before? I have an Amiga 500 that Joystick port #1 will only let the mouse move in two directions. Down and to the right. Other then that everything else works fine with the machine and I would really like to fix it. I tried swapping the CIA chips but nothing changed.
Any help with this would be greatly appreciated!

Sorry about that! I should have mentioned that I did try another mouse. I wish it was that simple.
I also checked the board over real good in that area for anything unusual but it looks fine. I'm thinking it's a chip but which one?

IDEAL,

Thank you very much for the information. I had a few minutes to look at it tonight and I tried cleaning the port like you suggested but no luck. I will check the connection of the port to the board but I think I did that originaly when I first recieved the computer. Can't remember!
I am taking another stab at fixing this and I am so glad I found this forum because the information has been terrific!

My wife and I spent a week on the Windjammer Steven Tabor out of Rockland and we dropped anchor in Bass Harbor for one evening. Probably the best vacation I ever took was sailing around the coast. It's a wonderful place the State of Maine.

banzai,

WOW what great information. I am going to go and get the Logic Probe because I tried reseating Denise and that did not work. I will let you know what I find as I dig deeper into this. Again Thank you for the help, I really feel that this problem is fixable and this machine can be something other then spare parts!
