I have a LG 50PJ350 that is not working. I looked through some other posts and found similar problems and did some work before posting this.
I found one bad resistor on the Power Supply board. I replaced it and the resistor beside it. They were both 22w 5 ohm.
The problem still was the same. I noticed that the D201 was not lighting on the Main Board. So, I replaced the main board and the problem is still the same. I was getting all the proper voltages to that board from the YSUS board, so I thought it was bad.
Today, I went back through and started unplugging the YSUS and ZSUS from the main board. With the YSUS unplugged and everything else plugged in, there is audio and it doesn't cycle throught the relays like it did before, it stays on.
With the YSUS plugged back in and the buffers unplugged, it goes back into the standby shutdown mode.
I am thinking YSUS now.
Any suggestions to try?
Thanks in advance.
