of IC 401). Adjust the coil
VL401 so that a voltage (2,5 ± 0,1) V at terminal 22 IC
401. In this case, the TV must
automatically tune to a station in the automatic search .
5.6 Adjusting the Focus
Turn on the TV to normal mode and tune in to a signal
" Color bars ". Adjust
Focus potentiometer (back of the upper TDKS
potentiometer) under optimum focus

5.7 Adjustment of the accelerating voltage
Apply a modulated RF signal " color bars » PAL B / G on
antenna input . Measure at
with an oscilloscope probe 1:100 voltage on R, G, B cathodes
CRT video amplifier module
CRT .
Attention ! Ground output oscilloscope probe should be
connected to pin 1 (ground) module
video amplifier tube .
Adjust all the functional adjustment (brightness,
saturation, contrast) to the minimum
position. Choose the most sensitive cathode tube .
Adjust potentiometer accelerating
voltage (lower potentiometer TDKS reverse side ) at this
cathode tube voltage suppression

1.1 Adjustment of the supply voltage
Connect a digital voltmeter to the cathode of the diode D607, set
AV mode and set the
accelerating voltage to the minimum acceleration potentiometer on
TDKS . Adjust the tension
supply (+ V) potentiometer R607 to the following values ??:
14 " ( 37cm ): 105VDC ( for A33EKS01h01 )
20 " ( 51cm ): 118VDC ( for A48EJW011x21)
