My LG 60PB5600 died a few months ago. I have it from March 2015 and it had average working hours. Unfortunately early this summer it died all suddenly. Error was 2 faded standby led blinks and then dead.
In the beginning of October I found some time to open it and check for anything burned visually but everything looked fine.
Then I searched on the internet and on you-tube for anything related on plasma TV repair.
I first checked the power supply board (fuses, bad components, voltages on connectors) and it was fine. VS was 206V, VA 60V and +5V present.
I then disconnected all other boards except the ZSUS. It had all voltages present on the P131 input connector, but on the P132 the +18V was missing, instead it showed around +3.5V.
On the images below you can see the TV opened flat on the floor, the ZSUS board and the P131 and P132 connectors:
