Re: Lg 60pk550
Ok, I tried to check ic701 for shorts. The only pin that I can tell is shorted to ground doesn't seem to be connected to a trace on the board. Does this seem correct?

Re: Lg 60pk550
I have the PS board back out and have located IC701. But wouldn't I need a diagram of the IC to know the configuration to determine if it is shorted? Or am I missing something? Visibly, nothing jumps out at me as being wrong.Leave a comment:

Re: Lg 60pk550
I checked VS and VA at the top left corner of the PS board. I assume these are the test points as they are marked VA TP & VS TP? No voltage fluctuation at all. Registers 0 volts. Let me know if I was wrong in my assumption about the test points.Leave a comment:

Re: Lg 60pk550
My apologies for the delayed response. I am on toddler duty today. Do you have your wire in the side that would be plugged in to the main board?Leave a comment:

Re: Lg 60pk550
Yes, sir. I checked the 3 large ones at the top right of the board and they were good to go.Leave a comment:

Re: Lg 60pk550
I'm not sure either. I told him the symptoms that I explained here. Either way, unplug the y and z sus boards and still the same 2 clicks then immediately after a third click. I've turned the lights off in the room to see if I can see any activity on the screen when I plug in the set and I can't see any action. The only thing I notice is the optical output on the main board lights up with the first two clicks then shuts off with the third.Leave a comment:

Lg 60pk550
Hello
I am looking for some help with my LG 60PK550. When I try to power it on
(remote or front panel) I hear 3 clicks from then relays on the power supply board. I called shopjimmy to inquire about repairing the PS board. I was told that it is not likely a PSB issue but it was more likely a control board or main board issue. What would your advise be on proceeding forward?... -
