My TFT is playing funny buggers! HELP

[knowley]

Hi people

My TFT screen has died, the picture seemed to go totally black, so I rebooted and its actually just very very very dark, I can see the outline of me desktop and such and when I press the button for the on screen controls you can just about make out its there!

Any ideas? Obviously its bust anyone shed anylight on whats gone wrong?

and after unplugging it and leaving for a while it works fine!

edit:

Can TFTs play games? It seems to happen when loading unreal tournament... the intro plays fine BUT when the GUI loads the screen goes BLACK, I managed to fumbled a QUIT from the menus, unplugged the monitor from the mains and plug back in again straight away and its fine....in windows anyway!

Sounds like a problem with the backlight lamp.

I managed to get into UT in safe mode (in a window @ 640*480) which seemed to work ok, but when I changed the settings to full screen 800*600 the back of the screen hissed like something was shorting? WIERD.

It now seems that if I leave the Dual Head Monitor ON in the display properties setup it works fine, turn it off and it does not.

My grpahics card is a Matrox G400 (not MAX) with Dual Head, do you think this points to graphics card problem?

sorted it.

One call to Matrox UK, and the genius sorted it for me.

Seems the refresh rate when loading the main part of the game was too high for the TFT, using matrox powerdesk you can choose a standard monitor type that goes only to 72HZ and now my problem has vanished!!!!!!!

When it was under dual head it was forcing the refresh of both monitors to 70 hz...all so simple ?!?!?
