I see. I will look when I get home. None of my pictures cought that detail.
I have been reading service and training manuals, but could not figure out how to determine if backlite diodes are fine if there is no mainboard 3.3V to supply TCON board and other controls. Unless it is this 220ohm to ground test. In that case, should I disconnect cables between main and TCON board (LVDS/power)?
I will contact repair shops and send my board out. I will verify that panel LEDS are fine first and then do that. Thank you for the help and your time. Cheers
Just had a TV come in exactly as stated above No backlight, button turns from red to white stays white nothing showing on picture. Main board needed to be reheated. LG 55LW5600
