I am using an old IBM 17" CRT monitor. Its quite old.
Of late, it will go black as it switch itself off. I know this because i cant feel the screen static after it switched off itself . Also i heard "clicks" noting that the monitor had switched itself off.
It will happen after 10 mins from switching on. Sometimes it will come back before switching off again.
At the moment the monitor will function again after it has been left off for sometime (an hour of so).
Hope you can let me know whats wrong with it.:@
