5. Adjustment
5-1. +B adjustment...Page 1 +B-ADJ
Adjust the voltage of the pin (4) of P1900 to 5.00 ±0.02V with R3714.
Note: Since 5.0V is a reference voltage of all power voltage, adjust it precisely.
5-2. Counter-bias adjustment
Vary the "COM BIAS" setting on Page 2 of the adjustment process mode so that the contrast be sharpest
(black looks most sinking).
5-3. TAMP adjustment
1) Receive the upper left of 75% white half colour bar signal.
2) See if the "Y" reading on page 2 of the adjustment process mode is somewhere following. If not, make the
"PAL TAMP" adjustment to get the "Y" reading in the range of AE thru BD.
3) If the adjustment of "PAL TAMP" is executed, write its adjustment value to the "SECAM TAMP" manually.
