you probably need to go for a universal remote , and check as the problem might be on the existing remote may not be working and then using the universal remote , u can undo the changes you have done .
Disconnect it from computer and power. wait 15 minutes and plug only the power back in, press the power on button. The monitor may display a message that there is no signal or something like that. If that happens the problem is either the cable or the computer. If you get no message then look for the menu button and press it to see if any thing appears. If not find the manual on line and read it. Many times monitors get over-driven by computers to the point that they can't display OR they self destruct.
Another way is to just unplug everything computer and monitor for 15 minutes. Plug in monitor first then plug in computer and press the power button, the display should display the booting information if the cable is good and the monitor is good.

You will more likely to have bad caps in the power supply which when they failed, will take out the fuse and MOSFET in the backlight inverter curcuits also. See example of failed monitors here: http://s807.photobucket.com/home/budm/allalbums
Try to unplug the monitor and totally shut down your PC. Wait 10 seconds and plug your monitor back in. Make sure the power is off on your monitor. Turn your PC on then turn your monitor on.
If you still don't get a picture and the light keeps flashing the monitor will need to go in for service. If it's no longer in warranty its best to just purchase a new monitor (will cost almost as much as a new one to fix)
i fixed this problem by unplugging the monitor, unplugging the video cables. Then hold down the power button while plugging it back in. Release power button and then press power button for on. It worked then. I got the icon for no signal, i plugged back in my monitors. Sceptre X9W
