CPD-G500 (by 2 users)

I also have the slightly diagonal (almost horizontal) lines showing up on my eight-year-old Sony 21" "Multiscan G500" CRT. They're only visible on dark backgrounds, and gradually get fainter as the monitor warms up, but they're still there. The "color restoration" in the Colors panel of the onscreen display doesn't help. Of course the monitor isn't capable of displaying black any more anyway; maybe I'll try the resistor trick mentioned elsewhere. But if I did succeed in getting the picture darker, would that make the "retrace lines" problem even worse?
