what exactly do you mean by Lightshow. I just recently read that in some cases this aquadag is not water resistant and it’s forming like a big cap with inside layer and the glass in between. But what’s the function of it other than striking people with electricityParts of the tube that you think are dirty might be a layer of aquadag. You don't want to remove that unless you want a light show every time you turn your monitor on.
Focus adjusts the sharpness. Screen adjust the brightness. You'll want to turn the monitor on with no game in it and turn the screen knob until the horizontal lines on the monitor just disappear. Once you dial those two in they are "set it and forget it" knobs. MS8-26SU has a second brightness pot on the chassis if you need to brighten things up a bit.
