Texas TI-66 Programmable: Toshiba skills to rescue Texas...

[Csaba Tizedes]

Hi,

I have a TI-65 in a very good shape and working condition, but on the LCD some annunciators and the segments of exponent display don't lit. And few weeks ago the keypad second row from the bottom (RST/BST/SST/X<>Y/SUM+/1/2/3/-) stops functioning.

Have you got any idea it is easily reparable?

How to dismantle this unit? ("To open the case it is enough to remove one single screw from the back cover." - is it same for TI-65? Where is that screw?)

Thank you!
Csaba
