Lg 42pt350-ud

I don't know how to exactly label this but upon cutting on tv the panel initializes for a brief 3-5secs and then goes off but the TV remains on till you cut it off. All the voltages are present.
The only one that changes is ER on the Z-SUS which starts at 20 in the first 3-5secs but then after the panel goes off jumps to 60-70..or it may be the opposite.

Could anyone guide me on this repair?
Of course now that I have wrote that last sentence about ER I am thinking it may be the Z-SUS.

Have you tried using the EXT AUTO GEN to isolate the main board? If you need help, post a picture of your control board.

I am not familiar with using that.

So, here are the ctrl board and main.
