I dunno... all I know is with this digital LCD meter even if I measured straight off the 175v onto my own 1 meg resistor, it dropped to 88 volts already, and to about 60 if I added another resistor, this is with just 175v to resistors to meter and that's it, only thing involving the tv was the 175v source. So that's when the 'meter is dragging it down' explanations I got sounded like it must be it as there is no other explanation I can think of. I tried a better Triplett meter I have also and it went up about 20 volts, but still only half of the 165v it said it should be with 175v + 2 meg of resistance.
