ON (1) Set picture mute to off (P-MODE: Normal1, 000), UNI-COLOR to maximum (1111111) and SHR-TRACKING
to SRT-GAIN minimum (11), and input T2 pulse signal (approx. 0.7 Vp-p) to TPA.
(2) Set picture sharpness to center (1000000).
(3) Monitor pin 3 and pin 43, and determine the time difference YDL00 for each signal at the 50% point as shown
below.
(4) Set Y/C-DL1 to +5 ns (1) and determine YDL01.
(5) Set Y/C-DL1 to +0 ns (0) and Y/C-DL2 to +10 ns (1), and determine YDL10.
(6) Set Y/C-DL1 to +5 ns (1) and Y/C-DL2 to +10 ns (1), and determine YDL11.
(7) Determine YDLA, YDLB and YDLC as follows:
YDLA = YDL01 − YDL00
YDLB = YDL10 − YDL00
T2 pulse signal
approx. 0.7 Vp-p
YDLC = YDL11 − YDL00
