Adjustment procedures (TV-880C/I/N)
1. VCC2 adjustment, VCC7, VEE1 voltage check
•Condition
Power supply: Vcc1-1 = 5.0 ±0.05 [V]
•Adjustment
Apply 5.0 ±0.05 [V] on Vcc1-1 (CP101).
Adjust VR100 so that Vcc2 (CP102) voltage becomes 4.00 ±0.02 [V].
•Checking
VCC7 (CP103) = 36.0 ~ 44.0 [V]
VEE1 (CP104) = –4.5 ~ –5.5 [V]
•Block diagram
2. LLD coil adjustment
•Conditions
(1) Signals
Broadcasting system: B/G,H
Color system: PAL color bar
(2) Signal level
Input electric field: 40 ±3dBµ(IF AGC full gain), P/S = 10 dB
(3) Other conditions
CCIR IF (Input electric field: terminated with 75-ohm resistance)
Power supply: Vcc1-1 = 5.0 ±0.05 [V]
•Adjustment
Monitor video detection signal (CP238) via a low-pass filter of 100 kHz cutoff frequency and adjust
LLD coil T200 so that its DC level is minimum (waveform’s amplitude is maximum).
(Reference: C= 1500 pF, R = 1 Kohm)
•Confirmation
There should be no waveform distortion (erroneous synchronization, etc.), under sensitivity (video
detector output level is abnormally small, etc.).

3.Free running frequency adjustment
•Conditions
(1) Signal
No signal (PAL standard signal should be applied only at synchronous check)
(2) Signal level
Input electric field only at synchronous check: 70 dBµ(terminated with 75-ohm resistance),
P/S = 10 dB
(3) Other conditions
CCIR IF input only at synchronous check (input electric field with 75-ohm termination).
Connect SYF terminal (CP729) and VCC2-7.
Power supply: Vcc1-1 = 5.0 ±0.05 [V]
Room temperature: 20 ±10 [°C]
•Adjustment
Monitoring HDB (CP305) with a frequency counter, adjust VR700 so that the frequency is 15.625 ±
0.1 [kHz].
•Caution
(1) Disconnect the wire between SYF terminal and VCC2-7.
Applying IF signal make sure that synchronization is normal on the display.
(2) Use input signal pattern conforming CCIR standard.
•Block diagram
4.Contrast adjustment
•Conditions
(1) Signal
Broadcasting system: B/G,H
Color system: PAL color bar
(2) Signal level
Input electric field: 70 dBµ(terminated with 75-ohm resistance), P/S = 10 dB
(3) Other conditions
CCIR IF input (input electric field should be terminated with 75-ohm resistance).
Apply voltage of Vcc1-1 = 5.0 ±0.05 [V]
•Adjustment
Connect color terminal (CP320) to GND (CP300) so that screen becomes black and white. Adjust
contrast pot VR300 so that the voltage between pedestal level and white level of B signal (CP740) is
0.80 ±0.05 [Vp-p].

(3) Other conditions
CCIR IF input (input electric field should be terminated with 75-ohm resistance).
Apply voltage of Vcc1-1 = 5.0 ±0.05 [V]
•Adjustment
Observing output signal B with an oscilloscope, adjust TINT pot VR301 so that the wave from H and
H' will be same.
•Caution
Do not connect COLOR terminal to GND.
Monitor B output signal with an oscilloscope via a low-pass filter (C = 2700 pF, R = 100 ohm).
