I don't know what the problem is, but I can say that I have had similar
trouble with my TI-85.  It seems as if  the batteries are dead, but they
aren't.  When I adjust the contrast, nothing happens.  The only way I
have found to fix it is to remove the batteries and then reinsert them,
loosing my memory in the process.  (The backup battery doesn't seem to be
working either.)  I was once able to fix it by waiting a few hours and
playing with the contrast some more.  That didn't loose my memory.  I
have no idea what the cause is, though.
