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.
