60PA5500 TV Shutdown

[Plurxtc1]

TV is shutting down. Power supply peaks at VS and VA voltage then drops. Could I be having an issue with the power supply? I already unplugged the Y-Sus and Z-Sus.
I did not see any of the 3-Pin transistors shorted that were attached to the heatsinks.
Power Supply is EAY62609801
Main is EBT62146301

You have to provide a set of power resistors to load psu outputs then test the voltages. Tell me the output tensions..

If you disconnect the main board from the PSU it should automatically power on and stay like that while plugged in mains AC, all voltages (VS,VA etc) must be present.

Whaat? Really it's a plasma? I may have said that because I have the same TV with same power supply as yours and if you only plug in AC it auto starts like every LG plasma. If you do that and have all the voltages stable then it's much more likely the main board shutting down. You only mentioned unplugging Y-SUS and Z-SUS, not mainboard.
