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.
