My MX8000 has begun to make the high pitch 15.625kHz CRT noise. I have read a suggestion, that you can use nail polish on a flyback, deflection yoke, or transformer (Liniaritetsspolen 413 / Liniarity coil 413 ).
But where is it - which one is it?
I think you follow the wire from the suction cup at that will lead you to the flyback transformer, and you can give that some super clue, silicone what have you. But I am not sure of it.
