The caps in these sets rarely bulge. Try checking the Horizontal Output Transistor (HOT). I suspect that it is shorted. The noise you are hearing is the power supply attempting to fire. With the defect further on, the power supply will turn itself off as a safety valve.

Unplug High voltage lead from HV splitter. This is a red wire going from HV transformer to similar (white plastic) device located up front, between picture tubes. Disconnect the one which is coming in, by strong energetic pull down with pliers. Leave those which go to picture tubs in. Make sure that disconnected wire is far from other components or metal parts (high voltage - SEVERAL INCHES SPARK CAN OCCUR) Turn the unit on - if different than 3 blinks - the splitter is your problem.
