i'm on step 8:
however, adjusting the R GAIN pot does nothing08. Adjust the RGB GAIN/DRIVE controls on the remote board until the grid is really white without bleeding out/turning blurry
the G & B GAIN pots bring the grid up in their respective colours as they should.
but no joy from the R GAIN pot.
the R CUT OFF pot brought up Red, so this issue seems isolated to the remote board?
ANY help would be appreciated!
