Try check for dry joints in the transformer pins and also the value of the tuning capacitor near the high voltage transformer.

The lcd monitor is designed to support on certain resolution and if your resolution is within the lcd monitor spec then it will display it otherwise there is no way to set. You have to check with the lcd monitor manufacturer support center to see if they could provide you with any solution to run on this special type of resolution.

Suspect a bad backlight because it can cause the display shutdown after few seconds.

Try remove the power IC and turn on the power and it should have about 15 to 20 vdc. If it shoot up more than the voltage then it will burn the ic. Try to trace back from the supply pin up till the filter capacitor. You may also try direct replace the filter capacitor and bridge rectifier to see if the voltage will back to normal or not.
