I've got an SL500 that one day just decided to stop lighting up the backlight. I tried replacing the inverter board, no change. I tried replacing the screen, no change. I whipped out my multimeter and beeped out the cable running between the main board and the inverter board, and it tested fine. I tested for a DC voltage into the inverter board with the laptop powered on, and got nothing.

Any ideas what could be causing this? I'm going mad here trying to solve this problem. Am I down to the point where I'm going to have to replace the main board for $300-$500?

Has anyone else experienced anything like this before?
