 but I opened it up and fixed that somehow. :)  However, now other things
 don't function properly.  I'll make a list:
 1. Link Port (Error in xmit occurs)
 2. Various buttons:  STO> button, tan button, and ^ button (no response when
 pressed)
 3. one row of pixels
 I would like to know if any of you have any ideas on how to fix these
 problems.

Well, i dont know how well any of these will work, but:

1. The wires may be disconnected. You can check this out and try to resolder 
things, and ive even heard of one guy soldering the end of a broken link 
right into the calc :)
2. Ive never gone this far into my calculator, but i beleive there is a 
rubber pad like thing between the keys and the board. Behind each key is a 
conductive pad on the rubber. If these are damaged, or not making contact, 
you may be able to figure out a way to fix that...
3. Probably a broken wire in the ribbon cable. Take a circuit tester with 
very tiny probes to it and find the broken wire. You can probably solder a 
new wire accross the break.
