On an M100 the leaking caps can cause a weak -5V which can lead to a dim LCD. 
On an M200 there is not a problem with leaking caps and I have noticed no 
improvement in the LCD by recapping one. My suspicion is that the LCD was never 
that great. I do wonder if the LCD polarizers have aged poorly.

Subject: [M100] M200 dim display

 

I'm trying to avoid blindly recapping my vintage computers, but I feel like the 
display of my M200 is dim, and only gets readable nearly at max contrast.

Are there specific caps to replace (for maybe a dc-dc converter for the 
display) that are known to make the LCD better ?

Or maybe other tips ?
