To adjust the screen settings.
Turn P3362 until a colour
reaches 25"5, place an
oscilloscope probe on the
cathode with the highest output
and adjust P3368 so the
oscilloscope trace reads
150V 0-peak (160V 0-peak TX -
25AD1D), then turn P3362 up so
the highest numbered box on the
TV screen reads 050 " 010.
