10. High voltage and Ib value limit test( random test )
Instruments： High voltage meter， Ib meter.
Input signal pattern： White vertical
Input signal intensity： 60dBuv (1 Mv rms)
Test means：Connect High voltage meter and Ib meter. Test voltage of different
Ib separately, It should meet the requirements below：
Anode high voltage (Kv)
21”
Model Ib, Ib scope
Value Diff.
Ib=50µA
Scope:
50µA&1200µA
28.0±2.5
<2
11.Heater voltage test ( random test )
Instruments ：RMS voltage meter
Input signal pattern ： Philips test graphic
Input signal intensity ：1 mVrms（60dBuV）to 50 mVrms
Connect the RMS voltage meter to the 2 ends of CRT glowers，test the heater voltage of
highest CR and Brightness, It should meet：6.3±0.3Vrms
12. CCD and VOL-CHIP function test
VOL-CHIP and CCD function test，please find the service manual in detail.
13. Initialization
Under the factory mode，press“SOUND”button，the screen displays“WAIT”,
when the screen displays “OK”, the initialization finished. You can enter the next
working procedure.
