Re: Lg 60PK550 Problem

I had previously checked R929 and found to be good, I'm glad that worked for you. Replacing the control board w a $25 replacement from EBay did the trick for me. Good to see another update on this thread, I plan on keeping this TV running for as long as I can.

Re: Lg 60PK550 Problem

I have the same issue in this thread but it seems that after the tv was trashed there was no conclusion to the thread. I have a 60PK550 that turns on intermittently, and by turns on I have no screen but all voltages check out except for VZB on the Zsus board, the value off of the resistor is 15V instead of 105v. If I can get it to turn on again I'll get a value when it works. I tried disconnecting the main board from the controller and placing the jumper to get a test pattern but still get nothing on the screen. I am suspecting the controller board right now....
