shut the TV down now no picture but does have sound,
ANSWERS:
"@truesaint ""a green screen on one side perfect picture on the other side"" could be a panel error. You do want to check the T-con board and the wiring going from there to the panel. Post some pictures of your boards with your question so we can see what you see. You will also have to try to see/access the ribbon cables that connect to the top of the LCD screen. Again, post some pictures by using this guide Adding images to an existing question

The LVDS cable does not carry the backlight. That would come from your LED board. The backlight will (should) always come on. Can you see your panel light up through some of the holes in the metal in the back of the panel. Check in a darkened room. If not then your issue may just be with the LCD board. Only hesitancy I have is with your """"a green screen on one side perfect picture on the other side"" that reeks off panel failure which I would really hate to see happening to your TV.
On the T-con board where you have the connector CNV1 just to the upper left of it should be a component labeled "" FP1"". Check that for continuity with a multimeter. Then with your set on check it for power. Set your multimeter to 50VDC and place red probe on either end of that component and black probe to any ground. What voltage does it read?

@truesaint since you did find that “did notice the lvds cable ribbon….is missing some pins” you do want to repair that first. Check the connector and make sure that it is okay. Let us know what you find. Vizio is a different beast altogether. Not to many schematics out for their TV’s ….
BTW if you use the @oldturkey03 I get notification that you posted something."
