field scanning mode.
4.5.3 Receive signal (A7), enter P6 of factory menu, adjustment SUB-BRI to let picture on the screen
micro-bright at T2 picture mode.
4.5.4 receive white balance adjustment signal, enter P5 of factory menu and set the picture mode to
standard, let the value of G.D unchanged, adjust R.D(-/+) and B.D(-/+) to let the white part of the picture
appear “white”.
Use white balancer to rectify the white balance under following conditions
color temperature:1200K+8MPCD x =0.270± 0.008 Y=0.283±0.008;
dark space: 6-10nit, bright space: 60-100nit
Note:
1. If the dark balance appears changeable while the color changes from minimum to maximum, adjust
BY.TV/RY.TV of P12 to let it coincide with the white balance.
2. If the dark balance appears changeable while connected with DVD, adjust BY.YUV/RY.YUV of P12
and let it coincide with PAL white balance.
The above values can be preset according the product coincidence, so you may adjust a little.
4.6 Horizontal/vertical breadth, line, center adjustment and raster adjustment
4.6.1 Receive A28 five circles signal, press PP button to select picture mode of “standard”, adjust V.SIZE,
V.SHIFT, H.PHASE, V.LINE, VSC of P1 and the items of P2 to let the picture coincide with the demand.
4.6.2 Receive G43 five circles signal, press PP button to select picture mode of “standard”, adjust
V.SIZE, V.SHIFT, H.PHASE, V.LINE, VSC of P3 and the items of P4 to let the picture coincide with the
demand.
4.7 Check
4.7.1 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, receive A7 signal and set the picture mode to “standard”, the high-voltage:
25.5KV±1KV, filament voltage: 6.3±0.1Vrms. The high-voltage may differ on the CRT.
4.7.2 x-ray protection check
Receive A7 signal, set the picture mode to “standard”, shorten TP1-TP2 with 10K Ω resistor, X-Ray
protection circuit should function, restart the TV 30 seconds after turn off the power source and it should
return to normal.
4.7.3 AV function check
According to the owner’s manual require, connect to the AV equipment and the AV interface:
VIDEO IN: 1 Vp-p 75OHM AUDIO IN: (-8±3)dBm>47 kOHM
S interface Y IN: 1 Vp-p 75OHM C IN: 0.3 Vp-p 75OHM
DVD Y IN: 1 Vp-p 75OHM Cr IN: 0.7 Vp-p 75OHM
Cb IN: 0.7 Vp-p 75OHM
