This tv has no backlight but has sound and picture. If I disconnect the t-con board from the power supply and turn the tv on, the backlight will flash on when unplugging. But only for a split second. There are only four wires going to the led strips attached to: D1+, D1-, D2+, and D2-. [image|2183608]I’m guessing since I see a brief flash the led strips work but aren’t coming on when being told to.

*EDIT*
I get 243v from D1+ and D1- but nothing from D2+ and D2-.
Added a photo of the Led Strip connection pinout. Here is the typed out version
