II+ problem

[JB <jbcole@ix.netcom.com>]

I have a problem with my II+

I just got it back up and running.  Everything seems to work OK except
some screen flickers and garbled text.  Is this garbled text lowercase
letters?  If so what do I need to display lowercase?  Also, I noticed
the letters A,C,B,T do not work.  (makes it hard to catalog a disk.) 
Anybody have any ideas why these things are happening?

Thanks in advance.

And thanks for all the responses to my Lemonade question.
