Oh! It's easy then all I have to do is solder some SMT chips! What am I
SAYING! SMT?!! yikes. I couldn't solder two wires together.
Anyway, what does the rest of the list think? Shoudn't the 230 screen work
just fine on the 2300? I understand it to be such that a 2300 MB will
drive SCSI or IDE and any of the duo screens without protest. This has me
wondering then, for if the 230 screen is garbled, too. then I need to
figure out if maybe it is a VRAM thing, or a cracked motherboard, or
what. It seems to me that the display is good and that the MB might be my
problem. In a sick twist of events, that could actually be cheaper than
replacing the LCD!
