Samsung NX58J7750SS Gas Range PCB Main

[repair_girl]

My Samsung NX58J7750SS Gas Range that I purchased less than 4 years is showing error code C-FO meaning "Check the PCB signals."  The gas burners work.  Nothing else works for more than 60 seconds.   For example, if I hit the reset (off/clear) button to make the code disappear and than then hit broil and start buttons, I can see the igniter working and the blue flame function properly in the oven, then after 60 seconds the C-F0 code appears again and the oven shuts off. I did an extended reset by unplugging the range for over an hour.  No change.  I inspected both sides of the Main process control board (PCB) and do not see any evidence of "burned out" components, traces, etc.  Samsung discontinued making the replacement for the Main PCB (part number DE41-00455A) and I was not able to find it in stock at any of the parts warehouses or on ebay.  Samsung repair service cannot (will not) fix because board not available.  In addition, none of the major board repair services (e.g., board medic) repair this board.  What can I do to further troubleshoot and repair or replace the board?  I want to try everything possible before throwing this less than 4-year-old relatively expensive appliance ($1400) in the landfill.  Help.  Please advise.
