My venerable 1400 that I’ve owned for decades and taken with me on every trip I’ve gone on in that time has developed a screen fault that I’d like some input on from those wiser than me in the ways of vintage LCD workings.
Vertical colored line, pixel wide, bottom exact half of screen from the faint horizontal line that splits the screen in north/south halves downwards, is always some shade of blue unless the background is solid black in which case most of the time it’s very dark blue but also sometimes randomly purple.
Is this an LCD fault and unrepairable without an LCD swap or possibly something else?
I have a small inventory of “parts” PB 1400s and when this condition showed up about a year ago, I figured I’d swap the LCD. In disassembling the donor machine, the bezel around the LCD crumbled in my hands into a million pieces so that plan was.... aborted.
I guess I’m trying to assess the risk/possible gain ratio here for attempting surgery and with knowing very little about LCDs, I’m finding that difficult. I did a bunch of research on LCDs in general that proved unhelpful other than telling me “it might be the LCD, and it might not” which is literally exactly where I was before the research.
A physically pristine (no cracks or scratches) PB 1400 is rare anymore, and I guess I’m hoping someone here has some more helpful information on this type of LCD, or PB 1400 screen issues specifically. It is the passive matrix CS type.
