Check IC-6001 (TL431)-primary PSU
Check JW-6022 (4,7R) in series between L-6005 and R-6001 (0R) near IC-6000
Replace fast recovery diode D-6202

hi chrissie the whining sound may coming from the transformer they do this when they detect low voltage, i'd test any diodes near by also any caps as well good luck
