a specified place.
c) Receive A12-PHILIPS(NTSC) signal
d) Select OSD H and OSD V.POS of factory menu4. Adjust OSD H.POS and OSD V.POS to let OSD at
a specified place.
e) Exit factory menu
4.12. Checking point
4.12.1 High voltage check
1) Connect High Voltage meter between CRT second anode and GND.
2) Receive A7 signal, set the control to “STANDARD”, measure the high voltage value, the reading
should be 25 kV±0. 5 kV
3) Set the brightness and contrast to minimum (zero beam current), measure the high voltage, the
reading should not exceed 27kV.
4.12.2 CRT filament voltage check
Receive A7 signal, set user control to “STANDARD” mode, use effective voltage meter to measure CRT
filament voltage, the reading should be (6.3±0.3) Vrms
4.12.3 X-ray protection check
1) Receive A7 signal, set user control to “STANDARD” mode.
2) Use voltameter to measure VD482 positive pole to GND voltage, the reading should be between 0.5
V~2.5 V.
3) Use 5.5V DC regulated voltage power with 1K resistor in series to touch TP1 (VD482 positive pole),
connect DC regulated voltage power negative pole to GND, X-Ray protection circuit should function,
at this time the TV set should be without raster, without sound. Disconnect the DC regulated voltage
power, picture and sound should restore to normal.
4.12.4 Picture and sound check
1) Receive standard TV signal.
2) Use picture control buttons to check color, contrast, brightness, sharpness, tint’s function.
3) Use sound control buttons to check volume control function.
4.12.5 Sub-brightness check
Receive A7 signal, set brightness to 75, contrast to 50, color to 0, sharpness to 50, picture left side 1-6
lattices slightly light up.
4.12.6 Color purity and convergence check (in normal way)
4.12.7 AV terminals IN/OUT check, S-VIDEO in check, Y,Cb,Cr in check.
4.12.8 Other buttons on the TV set and remote controller function check.
4.13 Degaussing
a) The unit has and auto degaussing circuit, the degaussing circuit works several seconds after turning
on TV
b) If you want to move TV or change the direction, turn off TV and ten minutes later the degaussing
circuit will work
