Had the tv for three years. Today I heard a "pop" tv went dark. Now when I turn on the tv, there is a short flash (with a slightly burned in image of what was on the tv when it popped), but goes dark soon after.

I've opened the set. Caps are visually okay, both power fuses are good, checked the Ybuffer for IC shorts, couldn't find any.

I've seen similar behavior when backlight LEDs fail. I'm not certain that's what is happening here, but it might give you something to look into
