My LG Top-Load Washer does not turn on but has power

I have an LG WT7600HKA top load washer
It does not turn on.
I have verified that there is 120v power to the outlet.
I unplugged and waited 30 seconds and re-plugged. No Start.
I have followed directions that I found in a YouTube video to check the noise filter. It appears good.
I replaced the Electronic Control Board. No Start.
I called an appliance tech who checked and said that the Display PCB Assembly was bad and needed replaced.
I replaced the Display PCB Assembly. No Start.
I don’t know what to do now.
I when I disconnect the power cord, press the power button for 10 seconds and release, press the start button for 10 seconds and release, I hear clicks as it resets.
Then when I plug in the power cord, I see a spark at the plug and I hear a loud click that sounds almost like a breaker or relay opening. This appears to be coming from the area of the noise filter.
I can reset by pressing the power button for 10 seconds and the start button for 10 seconds but then if I plug in again it sparks and clicks loudly.
If there is someone who can tell me what to check next, I would deeply appreciate this.
Thanks in advance.

**I got it running!!!

What I got wrong and why it took so long is that I had tried one or the other new but not both the new Electronic Control Board and the new Display PCB Assembly together. They had both gone bad. I needed to change both.**
