ge range model number ps978st1ss 760 code

[sixpoint]

The range will allow the turn on of burners or ovens, but will shut them off within only a few seconds,the only trouble code is a 760 code, of which looking at the service manual says to replace control board, but upon research on the net, suggestions that the problem is in the touch panel, which retails at 500.00 plus dollars don't want to get wrong, suggestions would be appreciated.
