Monitor comes on for moment then goes dark. Monitor is still on, but it is like the contrast is maxed out, very dark screen

put and external monitor and if fail remains then your gpu is damaged, if monitor goes good then your screen is damage or the video cable, so in that case will require a technician to fix it. good luck

Are you sure about power supply section? no bad caps with bulging tops at all, some bad cap may have flat tops but have high ESR.

To replace the crt picture tube will be an expensive exercise as they are not bulbs as such but the entire screen needs to be replaced as they are a complete unit.

Bad caps in the power supply, common problems. See examples here: http://s807.photobucket.com/albums/yy352/budm/Viewsonic%20V912B/

Go into monitor settings and turn "off" X-Contrast. X-Contrast will auto change contrast when backgrounds darkens. However, adjust manually the Brightness and Contrast settings to compensate.

front switch panel is suspect.

My monitors green light stays on, but the screen will come on for a second then goes off

Flyback transformers usually have 2 adjustable rods - 1 is for focus the other is for screen (G2) voltage. try turning Clockwise the Screen adjust with brightness-contrast at max. Till you see white diagonal lines, then go back until the lines disappear - then tune the brightness to your desired level.

Is the problem on all signal to display? If any signal is dark, the inverter is going bad.
