Samsung Front Load Washer Model WF45A6400AV/US - No Signs of Life.

The unit in question has worked perfectly since new (03/2022).  The unit completed a couple loads of laundry and then the issue started.  A fresh load was started and shortly afterwards the unit stopped, no idea as to how much of the cycle was completed.  Thinking the load was complete I went to change over to the dryer and the door would not open and nothing would show on the display.  Checked the breaker as this has happened before and found the circuit was still on.  I then unplugged the unit and waited about 30min and plugged it back in and nothing.  There was no indication of life.  This has happened before to a previous unit I ordered a new control board (Part# DC92-02379H) with the same results no signs of life.  I then figured the old and new control boards were fine and ordered a new front control panel (Part# DC90-29517A) figuring it had something to do with the touch screen display.....and no life still.  I have checked the wiring for power from the wall to the control board and from the CB to the control panel.  I could not check the circuit boards directly due to the clear epoxy or whatever it is covering the boards.  The fuse present on the control board was not blown.

I am at a loss.  I have looked for other circuit boards and do not see any. With no error messages I do not know what to check next.  Any help would be greatly appreciated.

Update:

After traveling down the information superhighway for hundreds of miles and seeing several mentions that the noise filter can sometimes fix the blank screen of death, I received a new noise filter (Part# DC29-00015G) from a friend.  I installed the new filter and heard relays click, the door unlock and the front panel to turned on.  GREAT ITS FIXED! Unplugged the machine and proceeded to put the it back together, pushed it back into its home, plugged it back in....AND wouldn't you know Mr. Samsung stood there with a blank look on his face dashing all hope of me doing laundry at home.

Any insight would be helpful.
