Dell Inspiron 600m - screen goes dark after about 60 seconds

Have a laptop and I'm trying to decide which part is causing this problem. If the laptop is powered sits for a while (hours), the display works fine for about 60 seconds and then goes very dark. I can barely make out the image but it's there.

External monitor works fine so it doesn't appear to be the video adapter. I've narrowed it down to the inverter or the CCFL. Both are pretty cheap to buy but the inverter seems to be easier to replace.

Is there an easy way to tell which is causing the problem?
 
It won't hurt to install a NEW inverter... do not install a used one... and CCFL tude... if you are experienced is disassembling the screen to get to the inverter.
Then if that is not the cause, you at least have anew inverter. The old one would have gone out some day, and the new ones are usually only $7 to $15.
And it might only be that a cable has pulled loose from it's socket
But with the 600m, it usually is the inverter.
