1492 brightness

[Nepa Coin Op]

getting closer with mon but one last issue.... appears to have a prob with either the auto bright or what appears to be too much green or blue, i went over the auto bright circuit, changed green and blue amps and rgb Ic and other components as well as caps in the area..... i must be missing something....... anyone have an idea where to look


Thanks

Did you check the brightness setting on the High Voltage transformer?

These are auto controlled with the bright pot sealed ..... I went over the auto bright circuit a few times already I must be missing something

Lower adjuster on the flyback will help with the white lines and the top adjuster is the focus.

Even auto brightness machines generally have these controls
Righty brighty, lefty.... darky

I have a few of these 1492s here none of them have movable pots for brightness it's frozen in place

On or next to the flyback tansformer?
