Sharp Roku LC55LBU591U No Video but Backlights and Audio ok

[NasTech]

Television don't display video but the backlights/Audio works.

I disconnected one side of the T-Conn cable and got distorted video on one side of the Panel. I taped off a few pins on the T-Conn cable both side of the panel displays but distorted video. I also replaced the T-con board results same blank screen. Any suggestions?

Jeeesh! Seems like we're the only 2 people in a 3000 mile radius that has one of these lol. I been saving this one all year but don't want to throw it in landfill. Found it on curb on a trash day. I hope you got yours running. Maybe a bad ribbon cable? or if you could reflash the mainboard image. At least you have power and image that's a good sign.
