Re: LG 42LE4500 No display
OK thanks. I've just googled and found it too.
see attached pic, are these the 12 measurement points?
do i measure with respect to chasis GND?
do u know what is the ideal resistance(during OFF),
or what are the correct voltage(during ON)...?
thanks.....

Weeks ago it just suddenly "die off", become no display.
(i think i heard a small "pop" sound when it went Black screen)
