I'm going to assume (dangerous thing to do sometimes) that you are reasonably skilled at disassembling electronics since you mentioned testing parts at random.
First, use a high power flashlight to see if there is an image on the screen when the back light goes off. If there is no image, then the power supply is going bad. You can inspect it for the obvious things like bulging capacitors, bad solder, ect.
If there is still an image, I would suspect the inverter board. You might still get lucky and find a fault on the power supply in the 12V line, but I would lean towards the inverter board.
