So basically my television turns black after around 10 minutes of usage you can still hear noise and everything I’ve seen people saying it’s a backlighting problem and I want to know if there is anything that I could do at home to fix it I can see things in the background when using it but it’s barely visible if at all.
Hi @lakika14 , You may be able to see the images on the screen better if you shine a torch at an angle close to the screen. Trying this in a darkened room will also help as they will be very faint even when using a torch. If you have a LG 60LM6450 TV here is the service manual that may help you to find the problem Here’s the No video / normal audio troubleshooting flowchart which may be a good place to start with, when the problem occurs Here is the section that shows the power board voltages.
