Input SIG5 (VL = 0 mV) to (A), adjust the BRIGHT parameter
with the serial bus data so that T44 is 9 Vp-p, and measure
the DC voltages on T39, T41, T44, and T46.

Input SIG3 to (A), and measure the maximum value
(VLIMMX) and minimum value (VLIMMN) of the voltage
range (black - black) over which the black limiter operates
when V54 is varied for T39, T41, T44, and T46.
Measure VLIMMX when V54 = 0 V, and measure VLIMMN
when V54 = 4.5 V.
Input SIG5 (VL = 0 mV) to (A) and set BRT to 0. Measure
the T41, T44, and T46 outputs (black - black).
Input SIG5 (VL = 0 mV) to (A) and measure the T39 output
(black - black) when P-BRT is set to 255.
Input SIG5 (VL = 0 mV) to (A) and measure the T44 output
(black - black) with respect to the T41 and T46 outputs
(black - black) when R-BRT = B-BRT = 0, and when R-BRT
= B-BRT = 255.
Input SIG8 to (A), adjust the T44 inverted output black level
to be 1.5 V with BRT, and adjust the amplitude (black -
white) to be 3.5 V with CONT. Measure VG1, VG2, and VG3
and calculate the following formulas.
