Thats Samsung for you. They are designed to last just right outside the warranty then fail. Typically the LCD panels are bad, and they are the most expensive part on that Korean unit.

It sounds like you have a Power Supply Board problem. The PSB is the center Board (towards left) after you remove the back off the TV. Remove Board from TV with the 6-7 screws. Replace capacitors CM852 & CM853; 2200ufd 25volts.
Thanks for using FIXYA, big IRISH.

First, check the power supply for the backlight. It's usually a 24 volt supply. Look for swollen caps. If that is ok, go to the inverter board and inspect for damage, ohm out the inverter transformers. Last is to test out the lamps seperately with an external inverter. If a lamp goes out this way, it is bad and causing the whole backlight to go out.
