Re: AppleColor RGB all-red display

The story continues:

Yes, it was a bad transistor for the red channel. It tested differently
compared to the blue and green transistors. Using better light, I could also
see scorch marks on the PCB from where I'd apparently made a short circuit
the other day.

Next step now is to find out what kind of transistor it is, and get a
replacement part.
