Z61T Backlight or Inverter or Fuse

Hi.  I have an almost 4 yr old Z61t that just stopped working last night.  I can see a faint image on the screen, but there appears to be no backlight.  It seems the likely failures are the backlight, the inverter, the cable, or a mainboard fuse.  I'm looking for how to easiest/cheapest/fastest to determine which is the true culprit, rather than just replace components willy/nilly...


Any ideas how to narrow down the possibilities?


I had closed the cover as I thought I was done for a while... a while later I reopened to continue working, and the backlight wouldn't come up.  Was plugged into AC with full battery charge at the time.
