Tv Has A Black Screen With Bright Flash Every Couple Of Seconds
I have an LG 55LB5550-UY LCD - LED Backlight TV 2014 model. I have a black screen that flashes every couple of seconds. There is an image on the screen - it passed the flashlight test. So far I have replaced: Power Supply Board, T-Con Board, Main Board and all of the LED Strips. It still flashes! the only thing I haven't replaced is the screen. Right now I'm suspecting that there might be a problem on the replacement power supply board since I've been told that it contains the LED control circuitry. The other idea I had is that there might be a problem with the software/firmware but I don't know where I can download it. The LG website says that there is no update available. Most of the YouTube videos I've found on the subject have been from tampatec and shopjimmy.com. Any suggestions before I part this thing out?
