Thats the Power Supply. You need to call a service man, please disconnect this unit from the Power, It is dangerous to leave it plugged in. what is happening is the set has developed a serious fault, to avoid a fire or explosion, the PSU has shut down the set. that noise you hear is the power supply struggling against the fault. trying to start. Please for safeties sake, get a "Quote" from a reputable, preferably an RCA recommended service centre.
