Hi folks!
I was hoping you could help me identify my issue with my TV, or point me in the direction of useful information. From my original research I thought it was the power board, so I bought one from ShopJimmy, but after I installed it the problem persists. I've looked around at a lot of proposed fixes and it's not clear what the right one might be.
I have an LG 55UL6200. On 3/14/2023 it stopped turning on. The red indicator light comes on when the power button is pressed. On subsequent presses, the screen barely goes on for a few milliseconds, and the red light flashes three times. It goes on for such a short time that it took me a while to notice that it went on at all. All I can catch is a glimpse of the bar in the top left that indicates what input it is on, before it is back off. Most of the screen is black the entire time. I have tried all of the easy fixes, like unplugging the TV and holding down the power button, using different outlets or cords, and leaving it unplugged for multiple days.
I read the LCD TV basic troubleshooting guide best I could, but honestly it's over my head. I've always had a small interest in electronics but I have no training. Only thing I could glean from it is perhaps it's the T-CON board.
Thank you for any and all help you are able to provide!
