The noise you hear is the power supply starting up and shutting down because of a fault drawing to much current. It is designed to only try starting up so many times before closing down, for safety reasons. The fault is probably in the Line Output Stage and is a job for a skilled person, as knowledge of the workings of the set and handling high voltages is required.

Sounds like high voltage arcing to me though the '3 times' is a bit out of character for this. If it is arcing then fire is the next risk, look out for a burning plastic smell as a clue. If is is arcing then the high voltage coil may need to be replaced and they dont come cheap usually something like £45 and that's before a repairman does the fix.
