SOURCE: Unexpected lamp shutdown
Remove the lower front panel by removing the 2 large round screw heads at the lower back corners, one on each side. Remove the retaining screw on the right side of the metal horizontal retaining strip in front of the bulb holder, remove bulb retaining screw in the upper left corner of the bulb holder. Pull the bulb holder out towards you and check for dust build up on the top screen on the bulb casing, if there is an abundance of dust it will restrict the airflow across the face of the bulb which causes it to heat up and turn off. Once the dust has been cleaned your bulb should now work as it should without a problem.

SOURCE: Power Light is On, TV is blank.
reallyme07, sounds like a "thermally intermittant solder joint" on one of the circuit boards (switch-mode-power-supply / inverter-supply) that are a key component used to light up the "cold-cathode-fluorescent-tubes" that supply "WHITE LIGHT" to illuminate the LCD panel. you didn't state what you would like to do or how to get it repaired?? Do you have warranty on set? how old is it? The same technology is used in small screen LCD computer monitors. you may want to visit YOUTUBE and search for and view the longer video clips of LCD monitor disassembly and repair videos FYI. The same kind of problems exist for them as do your lcdhdtv. In any case, a tech type person will need to fix it by an IN-HOME VISIT or CARRY-IN to the shop. I'm louie12fix on fixya or email@example.com Please rate this response if possible. Bye for now.

The backlight inverter board may be going out, or bad capacitors in the power supply.
