Re: WG6100 picture fluctuation

Certainly sounds like the high voltage is varying, but the DEFLECTION board
fixes it???

That would seem to point to the voltage regulators on the deflection board, but
the HIGH VOLTAGE supply is snapping???

Get a high voltage probe on this and see what you have. The regulator on the
high voltage supply might not be regulating OR might be set all wrong due to
the cap kit installation. Get that sorted out first before you get too excited
over working on the deflection board.
