Default Looking for help problem with a sony KP-57HW40
The beginning of the end for the blue CRT; internal leakage is causing
the G2 line's voltage to climb. Very common problem for Sony
projectors. Lowering the G2 for the blue gun will buy you some time.
I've had some luck clamping the G2 with stacked zeners to 450 volts.
