LG TV Black Screen Fix | How to Fix the Problem

[@bestvacationever]

Hello, I tried the T-con test and did not show any half picture. Will that mean the power supply might be defective?

I tried the tcon test and it showed half a white screen each time

Mine works for about 5 seconds full lighting picture etc..then it goes black and you can see the images only with a flashlight..this seems different from having no back lighting from power on..does this change the focus of trouble shooting since the leds themselves do fully power on then turn off?

Hey I am currently facing the same issue as yours how were you able to fix it

Same here, about 5 seconds. If I understood this video right, is he suggesting it most likely would be the power board failure?
