LG LED TV has backlight but no picture.
I have LG 55LA6205. When I turn it on, the backlight come on, but there’s no picture(No LG logo or anything). I checked the voltage on the Power supply, everything was normal. Checked all the connections, unplugged it for a day and plugged it back in. Nothing worked. Until I remember Sometimes I use the LG remote app on my iPhone. It has a feature to view what’s on the TV, like a second screen. So, I turn on the tv, and took a screenshot. It showed the LG no signal cube thing. So I took another one, this time I pressed the input button on the side. It showed the inputs screen. I researched before posting and couldn’t find a definite answer about this problem. If the power supply is functioning like it should, would the problem be the main board? But the main board seems to work. Or could it be the panel. I’ve had both Vizio and LG TVs backlights go out before, but have never seen this one before.
Es esta una buena pregunta?
