Re: LG 60PB6650 - Bad ZSUS (3.8v to YSUS instead of 16v)?
If you checked the voltages on the regulator ic's on the control board, and they are what they should be, you need a scope to check if anything else is operating, without that you would need to replace the control board.

UPDATE: Sent the Y-Sus, Y upper, and Y lower out to a somebody on ebay (https://www.ebay.com/usr/asa.vd.pc) and they said the boards are fine. Onto the next board, probably main logic.

Did you ever figure out what was wrong with your TV? I have the same TV and it has just gone bad. I turn on the TV, red stand by light goes off but there is no sound or picture. I don't get a blinking light on the logic board either.

Hi everyone?
I have L.G. 60PB6900 but is with the same issue...
I changed Y-Sus and Z-sus, but still 18v. are not present...
The green light doesn’t come on...
Did you find a solution for that issue....
