I expected that you had some bad caps. That 22/63 is the FEEDBACK cap--and if it goes bad, the regulator does NOT get the proper reference voltage from the Switch Mode transformer to know if it is producing enough voltage. SO, as a result it "floors it", pushing the SMT transformer to produce as much as it can, which is often OVER 250 volts (on the 135 or so volt line).!! This can and WILL damage many things, if the set is allowed to run this way at ALL.
That "squeal" in ANY SMPS is a dead giveaway of an off-frequency supply, and usually an over-voltage condition, due to lack of feedback. Sometimes it is due to "overcurrent " too, from an overload on some output line. IN EITHER case--it is a condition that CANNOT be allowed to persist--as it WILL damage both the supply and its loads.
