If you have another one available swap the motherboard into the working unit and check. If it works then problem is either from bottom module or the upper ribbon.
Had many with problem from upper ribbon and others from bottom module. Till now i never met this problem in the motherboard.
Hopefully its not from the motherboard in your case too
