How To Repair Monitor Display Dim Problem

This 17" CRT Relisys OEM Monitor came in with the complaint of dark display (can't see back raster). Even though at the front panel through the On Screen Display (OSD), you have adjusted to maximum the back raster still would not show out and the whole display appeared quite dim. Normally whenever we see this kind of dim display problem we will head straight to the flyback transformer and adjust the screen (G2) voltage control to increase the voltage to the picture tube so that the display will become brighter again.
