this one worked fine, then I think I went to switch from tv to hdmi source, them bam no video or backlight, no warning and no acting strange like some will do before a problem gets worse, just straight from working fine to that problem described.

Dont play any more with ribbons... you will damage them. take out the white heat sink of the MB Soc. and tell which type MT or MS.. also you have several Fuse on MB which are with F marked.. need to check them all with yours DMM, also remove the WIFI usb from MB and do hard reset again..

I'm having almost the exact same issue with a Sony Android TV. Have replaced power board and mainboard so I think they can be ruled out. Left right panel ribbon behavior the exact same as you when they are removed.
I'm thinking it could be a dead TCON as well as a dead panel. Did you ever fix this?

Disconnect lvds cable and make a jumper from mainboard 12v out and tcon 12v in, or mask every pin ov lvds cable except 12v, then turn on, screen should perform a self visual test..

Update. Just did the tape trick, got video for about 10 minutes while I went through the android TV setup. Then all of a sudden green horizontal bands and the display goes black. Can still hear the android menu music but no picture again. So panel issue confirmed? Hopefully that wasn't the panel nuking my TCON board cause I tried to make it work...
i can suspect your tape trick was not done well and/or you can have a partial shorted cap/diode on panel's distribution boards..
Great guess. Just had a very small bit of tape on pin 1 and it must have moved. Used a bigger bit of tape over pins 1-4 and we have picture back again. What's the downside to covering up more than a single pin? Worse image quality?
