Been troubleshooting this TV. I am getting 0.1V at pin 4 of connector CN6154. The green light is on steadily. I doubt this is high enough but the schematic I have is unreadable when I zoom in. A legible one would be great. Thanks.

Found training manual showing me that that pin should be 3V to turn on the inverter circuit. That means that I have a faulty mainboard.
