Question about LG 42LG50 42 in. LCD HDTV
Either one of the inverter boards has a failing capacitor on it, or the FL (backlight) tube is burning out.
in your case, the most likely suspect is the tube.
The easiest way to find out if it's the tube or the inverter board, is to plug each of the tubes into the others inverter. This isn;t possible on all models because of wire length, but in most cases it can be done.
If you have the same problem on the same side, it's the tube
If the problem moves to the other side, it's the inverter.
You can either look for failed caps on the inverter, or just replace the inverter - the former being much less expensive if it's just a capacitor or 2.
If it's the inverter, here's a video that might help you out in determining what capacitors have gone and how to replace them.

IF it's the backlight you'll have to get the make and model of the LCD panel itself, and then go to somewhere like www.lcdpanels.com to order the backlight (or the entire panel if you don't think you can replace the backlight without damaging the panel).
