PowerBook 160 Contrast Issue

Recommended Posts

So I took a long break from my collection and never got around to fixing this issue.

 

I have a PowerBook 160 that doesn't seem to keep its contrast steady. Messing around with the slider will fix it, but it constantly gets brighter, then dim.

Probably needs new caps on the control board and display. I have one that sorta does this. When it boots, its looks good then after a bit I have to adjust again - but then its fine. I figured caps since they can cause all sorts of havoc.

I've the same issue, planning to swap the caps on the inverter board. Figure that'll do it.
Doing the screen caps anyway, but I think the inverter caps should fix the contrast drift.
