Title says it all. When turning the tv on, the audio works but video does not. Have tried unplugging and plugging hdmi cable, swapping out for a different hdmi cable, and have tried unplugging and plugging the coaxial for the cable box, nothing works.
Hi @tamrielbound , Can you view the TV menu screens OK, you didn’t say? Have you tried a different signal source, e.g. a dvd player and checked that it works OK when using it? If you can’t see an image when trying either of the above, with the TV on and audio heard, shine a torch at an angle close to the screen and check for any images. They will be very faint if they are there so trying this in a darkened room may help to see them if they are there. If you can see images then there is a backlight problem with the TV
Describe tv model and to where you are connecting the cables.
LG sets made in 2018-2019 with BOE panels (including but not limited to European markets) are at a high risk of developing a fault with the screen panel/LCD module. The screen appears black, but the backlight behind is on - the ‘OFF’ state of LCD screens is black (blocks the backlight). Mainboards of these sets have two versions: ones with two wider #1 and #2 LVDS connectors (68 pins each, for BOE panels) or two a little shorter LVDS connectors (60 pins, for LGD panels).
