I have an Atari 5200 Trak-Ball that won't move the cursor UP...everything else on it works flawlessly, all the fire buttons, auxiliary buttons, keypad buttons, and the cursor movements of left, right, and down.  It just won't move the cursor UP.  I am looking for parts to fix this problem.  Anyone with any ideas, any parts, a CX-53 Trak-Ball that has other problems but the cursor moves in ALL directions (I'd be willing to buy it from you for the parts), any of these would be greatly appreciated.  Thanks.

Did you try it in the second port?  Put a 5200 controller in port 1 and trak-ball in 2 and fire up Centipede and see if it works!

Some examples of where one might find replacement chips.

I've repaired four of these units now and, so far, all have been fixable by replacing a chip or two.
