No green flashing light , but surely if the ysus was at fault i would still get the 18v supply leaving the zsus to feed ysus? With the ysus disconnectedLast edited by johnjgjohn; 01-24-2016, 05:11 PM.

Nope, everything has to be working perfectly for this TV to show perfect voltages. It's a pain in the arse.
It's almost certainly a failed y-sus.
Don't know why LG decided to leave their trusted y-sustain and buffer layout and copy the more recent Panasonic SC boards.
Take a close up picture of the lower half of the y-sustain, I probably know what's failed.
