My father's PC has just been upgraded/fixed & returned to him but his existing monitor (flatscreen LCD) is basically showing a black image though he can see the desktop screen very, very faintly in the 'gloom'.

He has adjusted the screens own settings but is unable to see enough of the desktop to do anything via Windows.

He has checked & double checked the connections. Is there something obvious he may be missing?

a crt monitor then i would have guessed that the tube had gone, just like a t.v. But seeing as it's an LCD display i have no idea :o( . Anyway this post will act as a bump to get you to the top. Maybe someone else can help you :o)

This sounds just like a Laptop screen when the back light goes

It may be faulty graphics card or the card may need reseating. PS also check for a bent montitor plug pin

Only suggestion I have is to try the monitor on someone elses PC and see if that works. Also check the graphics drivers are installed though even if they weren't you should still get a well lit screen.

I have little experience of LCD monitors, but this looks to me like it could be the illumination tube has died or become disconnected. The LCD monitor works by illuminating a background with something similar to a fluorescent tube and filtering the light through the liquid crystal elements, so without the illumination tube I would expect to see the effect you are describing.

Thanks chaps. One of the upgrades did involve a graphics card. This said, his PC did work on the engineers monitor.

MuddyPaws does also say that if he shines a spotlight at the screen this is when he can see the desktop all be it far too faintly to operate anything- ie virtual black out.

Any other ideas?

Most LCD monitors have a message screen or setup menu. You should be able to see this even without the computer connected. If this screen is also dark, then it's even more likely that the tube has failed. I haven't yet found a UK source of these tubes, but this US site lists them and they don't look too expensive click here

Have you got the monitor drivers loaded?
