As for whining sound , think you may have a bad cap in power supply - if you had already checked the ones in the power supply ; look for another that is known as 'decoupling' and has a resistor to basic power and filter to ground to filter it a second time and it feeds the Audio portion. As for CRT blinking ; turn the Master screen way down and fire up set ; wait 5 minutes and slowly turn it up and note where the pix comes in and go up more and note where the pix blanks out ( may have to unplug set to 'reset' ). If that "Range" is narrow ; then reduce greatly the resistor values in the Heater circuit to crt and try again. CRT may be getting worn out. Best: Eugene
