Narrative:
Shortly after takeoff 'tat probe' EICAS message illuminated. Completed irregular procedure and contacted maintenance. Was informed that the tat heat circuit breaker was non approved for cycling and could only do so by exercising emergency authority. I chose to do so cycling circuit breaker(s) L-24 and R-25 to no avail. Inoperative components were autothrottle; TAS indications; tmc; LNAV; VNAV; and FMC time and fuel scores.
