The AoA display getting dim sounds like a separate problem, but the E11 
and E33 may have been due to water in the sense lines, or perhaps a 
loose ground wire at the red and black pushbuttons. The E33 just means 
that some other error was reported and, (from the manual) the E11 means:
> Reasonableness ramp check of the wing
> differential pressure transducer is not within

I'd remove the sense lines at the CPU and *gently* blow them out just to 
be sure, but is it possible that you may have inadvertently touched the 
black and red push buttons? As you know, the black is the dimmer button 
and the red is the test button which would account for both your 
problems. Is it possible that ground wire to those two buttons is loose? 
I'd closely inspect the wiring to those two push buttons.
