Hi first thing to do here is to see where the problem lies. use a vga / monitor lead from your laptop to an external monitor or lcd/plasma tv in pc mode and by pressing fn and your monitor switch key think its f5 you should be able to determine if your screen is at fault, a common problem is the screens inverter or backlight bulb, if you manage to get an image on your external source then you its sure to be screen related wether it be the inverter/backlight/or even your internal screen lead this process can save money and time, you would then need to test the inverter to see if its this, the inverter is normally the cheaper option as the backlight can be a long tricky process.

I hope this has helped please rate :)

Screen Goes Blank
Ive seen this on other monitors. Look for a 1 and 2. Some monitors do NOT auto detect a signal, and this one might not. Look for a way to set the monitor from Digital input to VGA input. Try that and see.

My monitor is blank?
Could be you monitor or vga card have gone bad. If you have a known working monitor connect it to your pc & see if it show something. I fit does, your old monitor maybe bad & maybe replaced. If it doesn't show anything, you vga card maybe bad. You can replace the vga card which maybe the culprit.

It is most likely the connector between the screen and the motherboard that is loose/failing. I would check that first, before taking it in for repairs..
