TCL-THOMSON Electronics R&D Center (Shen'Zhen Lab)

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
Model

11.Heater voltage test ( random test )

Instruments
Input signal pattern
Input signal intensity
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.
