Samsung PN59D530 Won't Turn On

[AFajitas]

Got this Samsung PN59D530 59in plasma from a guy that said he had two of them that both got fried after a lightning storm. Both fuses on power supply check out okay. On the header that goes from power supply to main board, I am getting 5.3v for PS_ON and 2.7v for Standby, but no readings from any of the other pins. When I unplug the cable from the motherboard standby then reads 3.8v instead of 2.7.. I tried to jump standby and ps_on and still got no readings from the other rails, but I think maybe I am not jumping it right.

How can I determine if it's the mainboard? What's the proper way to force this tv on without a mainboard? See pics.

To jump the power supply on the PS-ON signal needs to go low.

So you'll need to connect PS-ON to GND

And in some models VS-ON to 5vSTBY


I suspect you have a faulty mainboard as when you press the power on button the ps-on signal should much lower than 2.7v

I think it is a bad main as well. I got a good deal on a replacement and will keep you guys updated.

So did you swap the main board?
