Has anyone come across a problem of a monitor that seems to be working ok but some times the screen on start up will just not work. the On Off button has a light by it , when the monitor is working this light is green but when I dont get a picture the light is orange .The monitor is a time so what the actual make is anyones guess.
Origonally the problem started on a comp with onboard graphics, so L tried it on two more comps one with a GF4 Ti4200 and the other with a GF3 Ti200 sometimes the picture would come on sometimes not, which makes me think it is something to do with the monitor.
This can sometimes happen because of a switching fault at the motherboard, but seeing you have tried two different computers, it rules this out.
When the Orange light is showing on the monitor, it's in stand-by mode waiting for a signal from your motherboard/graphics card to switch on. So I think that after trying the options you mention above, it does seem to narrow the cause down to either the cable or a intermittent fault in the monitor itself. j.
