Today on the bench is the PowerBook 2300c. When I got it last year, the display had problems: two large vertical stripes were glitching.
I opened it and used alcohol swabs on the display columns which may have had cap fluid leaking onto them. The visible caps were on separate boards.
I suspected that there's caps on the other side but I was terrified to take that board out for fear of breaking the tiny flat ribbon connectors on those columns.

One year later, the PowerBook 2300c display has exactly the same problem in the same area. So I tore it down again and swabbed all of the column pads on the LCD again, but maybe not as thoroughly as I did previously. Much to my surprise, it looks ok again.
The display is a Toshiba LTM09C035L.
So, the question is: was this leaking capacitor related or maybe a janky LCD flat cable?

My current theory is capacitor problems affecting two specific connection areas determined by this diagram of the LCD flipping the display to match the rear.
But I reaaaallly don't want to break this LCD by trying to lift this board away and having those thin flex cables

Also related: anyone have an internal SCSI drive flat cable from the inside of a PowerBook Duo 230 or perhaps a dead Duo 230? I'd love to convert this to a BlueSCSI and get WiFi (the current drive and cable inside is IDE).
