Sounds like your monitor isn't set up at the correct resolution.

If you're running Windows, go to your Control Panel and into Display > Screen Resolution.
Try setting it to 1024x768 or higher.

You do not need the driver to get the picture on the screen, if you do not driver installed, the computer may not be able to display the native resolution setting, but it will not cause you not to have picture. I do not install any special driver on my monitor testing PC, otherwise I will not be able to fix any monitors.

(Programmes - Accessories - System tools - System restore)

There are little tube lights in the monitor that are like the big florescents in buildings. They are powered by a voltage inverter. What you are talking about sounds like the inverter. If it was the lights you would have gotten bad color before it went out.

Is your remote working? If so use the key pad and open up the menu- look for advanced settings, press unlock (parental controls) also use the default setting to auto reset the channels....

Center pin is Positive.
