LG 55UH6030 4K Smart TV Screen Dim

Текст:

I started with a screen that was flickering on the right side when plugged in the outlet.
I tore it down and replaced the two LED strips at the bottom of the screen with these:

I put it all back together and have a viewable picture, but it is now really dim, being brighter at the bottom and fading darker towards the top.
I checked energy saving, backlight level, and picture brightness, and none of those made a difference. I took it apart again to double check I had all of the screen layers in correctly.
I checked voltages on the power board while powered on and have 275v on both LED+ wires at the front and back of the connector. I also have 13.25v on the middle wires at the connector going to the main board.
I did notice that if I unplug the main board from the power board, the LEDs do not light when plugged in the outlet. I would be grateful for any advice. Thank you.
