Description

The monitor is currently quite dim using either composite or S-Video inputs, even if I turn up the red, blue, and green gain all the way. The mouse cursor outline is bright white when used with a Mac, but everything else is quite dim.

Apparently there are two potentiometers to replace, and then a capacitor to be added, which may help with the main issue.

Then separately, recapping the entire unit may help with longevity.
