Re: Monitor is on, goes light to dark in 1 second

I have the same problem with my Dell 17" monitor. I've been reading and what others with similar problems say is that the power supply has a bad capacitor.

Monitor goes blank less than a second after turning on.

Sounds like either there is a bad connection from the computer to the monitor, or the monitor has a faulty power regulator, causing the monitor to overheat prematurely, and shut off.

Used as second monitor suddenly stared to go dark

If the screen is lighting up for a fraction of a second when you turn on & then goes dark, this indicates a fault either with the backlights on the screen or the inverter part of the monitor. You can check the backlights if you have access to a backlight tester, you need to remove the rear cover & connect the backlight cables into the tester, if this checks ok then look for a problem on the inverter board, checking the capacitors for any signs of distress.
