Did you escalate to the BF concierge immediately while on the ground? They would have called maintenance over if you boarded early and gave them enough warning - this is why I'm always among the first to board BF and check the full operation of my seat and IFE within the first few minutes and get with the Concierge immediately if there is a problem.
Sure enough I have issues IAH-NRT and NRT-IAH, and was re-seated before departure.
