Ohm range.
Test the 3 wirewound reistors first.

I think there is something here. I test the resistor, r927 = 10.3 r928 = 10.2 r929 = OL

I love this side and the people that take from there time to help other. HAMIE, this is one more for you and your team, job well done, what surprise me more is your patience to work and explain to a person that know not much about electronic. I feel like a champion, especially when i show it to my wife. But between you and me, you know who the champion is. Thanks, Champ.

I believe that means the main board is bad. The power supply seems to be working. The X and Y mains and buffers seem to be working. That really only leaves the main board. Someone with a little more experience may chime in soon.

Re: LG 60pk550 turning on and off

What should i do

[Hamie]

Re: LG 60pk550 turning on and off

Reflow the mainboards processor.

Put mainboard in an oven and bring it up to 120 Celsius.

Then use the heat gun and bring processor up to 220c

Leave 20 mins before moving the board.

I had the same issue on a 50PS3000 motherboard was causing Vs on signal to mess up. When ever I pressed lightly on the motherboard it caused the Vs on signal to go all over the place lol silly Lg junk.

Re: LG 60pk550 turning on and off

I have the same tv. When I leave the ribbon connector from the logic board and the power for the Y Sus which also powers the X drivers along the bottom connected but I unplug both Y buffers I get a snowy picture for a brief second. Does this mean my Y Sus and buffers are bad?
