I replaced an old crt type monitor on my computer with a tft flat panel one this worked ok for a time but now after being switched on it works for only a short time may be ten minutes then goes black no information on the screen at all If I switch the monitor off then on again straight away the on screen information returns but only for a couple of seconds the computer is still running normally all this time I can continue the switching on and off process to enable me to shut down the computer I have tried the monitor on other computers systems it does exactly the same I have today turned down the brightness control to 50 on the monitor menu to see if this action does any good would be very gratefull for any suggestions The monitor is only fourteen months old
Take a flashlight and shine it at the LCD screen while after it goes black. If you can see the screen images still then your backlight is the problem. Let us know what the results are and please don't forget to rate this post.

tried this but still not cured

I Have exactly the same problem. About the same time frame. When I firt turn the monitor on the sreen is visible only for a few seconds before the backlight goes off. The Display is fine other than that. I also have the same problem with a 17" Dell LCD.
