Re: Lg 42pq3000 dead
"As above lg 42PQ3000 totally dead , no led lights , I have swapped the power board as I had 1 spare, but the fault is still there", this is said in your first post.
In #18 you reported as soon as AUTO_GND goes to 0V stand-by also goes to 0V, if you plug in the main board nothing will change, if you jump 5VSTB, 5V, 12V and 17V, ACDET to it ignoring all other signals it may work.
