[QUOTE=andy;3179849]Does the HV adjustment have any effect? There are two general causes of low HV. Either the flyback isn't outputting enough voltage (a bad HV rectifier could also cause this), or it's being loaded down by the regulator.
The HV adjustment has little to no effect. A strange thing, I can't get the screen to go black. The picture I posted of a blank screen was with the brightness turned all the way down.
