THIS WOULD PROBABLY BE AN INTERNAL PROBLEM YOU PROBABLY CANNOT FIX.SOME TYPE OF INTERNAL CONNECTION OR GROUND.YOU PROBABLY WILL NOT BE ABLE TO DO ANYTHING UNLESS IT IS UNDER WARRANTY

click on settings and check under contacts to display and make sute its set to all

more likely a fault with the wiring or an invertor board problem

Please refer to the nearest mobile service centre for FLASHING.

Thanks!

You possibly could connect it to a monitor or tv to see if it shows up on there. But, yea sounds like you have an internal problem with the screen disconnected.

well mayber the flex(ribbon) connecting your lcd to the board is damaged try replacin it with a new one.

You may have a burned video adapter.

A trouble shoting setp you can try is attatching an external display and seeing if that works.
Also try the function F5 key combo. I think that is the ASUS mapping to switch display output.

on ooptions screen, click box that says only show settings the monitor can handle. Then try changing the horizonal and vertical settings on monitor to match it up with your settings.

On your windows main screen, right click, then properties, then settings, check all the settings

when you press the power button does it show a green light?

try using batteries with 2500mAh/ 1.5 volts or higher

Try unplugging the monitor and then restart, and then go back to default settings.
