I've worked on half a dozen of LCD TV's with the same symptom.
I all cases, they acted like you are describing.
They turn on perfect, and only stay on for about a second, and then the backlight turns off.
After replacing a lot of parts, they all turned out to be worn out display lamps.
I'd suggest starting checking that first. Think of the backlight display lamp to be similar to a worn out fluorescent light tube. |

Backlights are usually integral to (part of) the panel. _________________ You're over there, I'm over here. |
