LG Washer issues

I have an LG washing machine that is doing 2 weird things:

  1. It’s recently started to turn on by itself - not actually running a load, but just turning on the display panel and making a beeping sound.
  2. At other times, I load the washer to run it, but it won’t turn on - like there’s no power. I unplug the cord, plug it back in, and it starts up and runs the load without any other issues.

I’ve heard it could be a control board issue. Any confirmation or other ideas? Thanks.
