Neptune Maytag Washer Control unresponsive

I have a Neptune washer- model MAH5500BWW. Console touch pad lights but after a minute, they all start blinking, and I cannot change any of the settings or turn the machine on/off.
I tried doing the diagnostics test but the machine does not respond when I try to go into the service mode. I unplugged to try to reset, no change. I replaced the control panel 9From ********) as well, but no change. Please, advice… Serial number is 74951737AC.

I have seen similar older posts, but with no response… Hoping to get one…

Thanks in advance!
