Squealing is usually the osc off frequency. Not sure my imagination can do much with"sound step" though.
Do you have an oscilloscope? If you do you can use that to adjust the osc with the output pulled. If not get video on the screen and some vertical deflection and adjust the H osc according to the procedure in the Sam's photofact for your chassis. A minute or so of ~250mA shouldn't kill the flyback, much longer is not advisable though.
