LG 60LN549e no display after LG logo on power up
TV shows the LG logo on power up then is black. With a flashlight I can see display when accessing menu mode. The TV has sound. I have the back off and there are no bulging caps. The leds flash when turning on the tv (probably during the logo display).
ANSWERS:
@sdp1234 check the voltages on your power board to the backlight LED’s (set your meter at something like 200-250V and let us know what voltages you get. You can measure the voltages on the power supply against hat is printed on the board. See your pictures #2. My first suspect here would be the backlight array having failed. LG has had bad issues with this on their models. If your voltages are okay you may have to consider replacing the backlight. For that you will have to dismantle your panel . PITA but doable. Just do not mix up or turn any of the diffuser sheets over etc.
