vizio m3d650sv panel questions
hey guys working on a vizio m3d650sv for a local pawn shop and originally started with 3 vertical lines on right hand side...shop ordered a tcon board & they installed and lines were still there...then after having them switch the 4 ribbon cables around lost all picture including backlights...i went back to troubleshoot & noticed that when you disconnect the red wired cable from either tcon or inverter board you regain backlights...after doing some research i've concluded that this is probably a tab bonding issue in reference to the lines but as far as the backlight issue do you guys have...

Emerson LTDn42v68US comes on then shuts off
typically this would be an issue of the backlight inverter (at least from my own experiences) but i've replace BOTH backlight inverter & AV (Main) Board...just trying to verify that i'm not going crazy and that replacing the power supply SHOULD resolve the issue
TV turns on (3 flashes of the standby light) i get the input notification box in the upper right then the screen immediately turns off (yes i lose backlight when viewing this process from the rear) i have some pics attached but don't believe they'll be of much assistance
thanks for any help guys!
