@drewgraham: Were you able to identify the problem?

I am having quite a similar problem with my Viewsonic LCD VA1912w. It worked fine for 1.5 - 2 years, 3 months ago I started to notice some flickering over any dark/black display, e.g. a black desktop background. Upgraded drivers to no avail. Left it as such, changed dark themes to light and forgot about it. Mistake?

Now, when i turn it on, it displays/flashes some random white/gray lines + makes a bzzzz noise for 1/2 a second, then fails (it's like switched off, power button still on). After several (started with abt. 5, keeps increasing) attempts to turn it off and on again, it will finally display. It does that only when it has cooled down, i.e. if it has been on for hours and you turn it off and on again / or restart the pc, it will display.

@spudder: you think it is the inverter?

How can i save my slowly dying monitor...
