A pix of the screen would be nice. What you or talking about sounds like poor filtering in the low voltage supply. Now its not 60 cycle hum but 15750 cycle hum from a scan derived supply. Main filter C101 a 4 section can and scan filters C903 1000 mfd 35v and C905 330mfd at 35v are the power filters. All the best, Tom.J
