LG screen on, lit, but with no picture.
TV was having issue for a few months, progressively worsening. Lots of horizontal lines out on the screen, then the whole picture would kinda shutter. After some research, we decided to clean the tcon cables. Since then, the TV turns on, does not appear dim, but with no display. No logo, cannot access settings, just black. Have replaced the tcon board, tcon cables, and main board with no fix. Does anyone know what could be going on? Model LG60UH6035-UC.BUSWLJR
Backlight
Main and tcon boards
Multimeter w fuse
Is this VCC? If so, I got nothing on the meter when tested...
Power board
Questa è una buona domanda?

@amonjlp that sounds like your panel not getting any power. Post a couple of good pictures of all of your boards and your interconnect ribbon cables between them. How did you originally clean the T-Con cables? Your replacement boards new or used?

@amonjlp also what do you mean by "does not appear dim" do you see the backlight turning on through the holes in the back of the panel?

@amonjlp yes, I can. Do you have, or can you get, a multimeter?

Cleaned the ends of the original tcon cables with a little rubbing alcohol, but those have since been replaced completely. All the replacement parts were used, but we're from cracked/broken TVs and assured that the parts were in good working order.
