Use white balancer to rectify the white balance under following conditions
color temperature:8MPCD x =0.270± 0.008 Y=0.283±0.008; dark space: 4.5nit, bright space:
60nit
Note:
1. While the colour saturation changed from maximum to minimum, if the dark balance appears
changeable,adjust RY.TV and BY.TV (P12) to let it coincide with white balance.
2. If the dark balance appears changeable while connected with DVD, adjust BY.YUV and RY.YUV
(P12) to let it conincide with white balance.

receive signal (G43), press the PP button the picture model, set standard adjustment the P3 of
V.SIZE and V.SHIFT and H..PAHSE and V.LINE and VSC, let the P4 coincide with request.
4.11 High voltage and filament voltage check
Connect a high-voltage meter between anode cap of picture tube and the ground, measure the filament
voltage using rms voltmeter, set the picture mode to “standard”, the high-voltage: 29KV±1.5KV,filament
voltage: 6.3±0.1Vrms.
4.12 x -ray protection check
Receive local TV signal, set the picture mode to “standard”, shorten the circuit and measure the
value of TP1-TP2, restart the TV 30 seconds after turn off the power source and it should return to
normal.
