There are two places to look for the problems, the backlight inverter board and the power supply. Look at the power supply first since it is easier to get to, look for burnt parts, bad capacitors, etc.
Please post back what you find.

I think you have a defective power board. the pop sound in coming from the board and giving you a low output voltage. do it yourself price about two hundred for parts.
