Some keys display the wrong character. they don't change when they're already

sometimes comes out as 'X' then sometimes as 'x'. C displays 'A'
or 'a', 3
displays a 1, ect. I tried to clean the keyboard w/ compressed air, but no
luck. Any ideas?

When i hit some keys, it displays the wrong letter. Sometimes it
displays all caps then all lower case. What's wrong with it? How do i
fix it?
Is it a keyboard problem or a display problem? Can you give some examples
of what you type and what it displays as? Is it consistent?
Try typing some BASIC commands, using the right keys (no matter what they
display as for the moment). Do they work (even if displayed incorrectly),
or do you get syntax errors?
Do characters already on the screen change. In other words will a 'C' on
the screen change to an 'A' or to a 'c' or something like that. If so,
then there's a fault somewhere around the video memory. I have the
schematics for the old version of the Model 4 CPU board somewhere.
Or is it that the keys generate the wrong characters? Can you type all
the characters you should be able to (even by pressing the wrong keys)?
