Device “YPY”-10
WARNING!
1. All procedures with breakdown device must be executed witth dielectric
gloves and on dielectric mat.
2. The aerial with signals should be disconected.
3. The device shoul be surely earthed.
1. Stop the TV set front a mirror on conveyor.
A plug of TV power cable connect to the socket of electric resistance control device.
2. Connect a grounding plug of “aerial” type of device to the TV aerial socket.
3. Output wire should be connected to “=” marked terminal, the switch “=” of device output
voltage should be in position “=”.
4. Press the key of output voltage switch by left hand and keep it in this position.
5. Press the output voltage regulator and rotating it evenly increase the output voltage to 4240 V
gradually (in 3-10 seconds) controlling it by means of device instruments. Hold the 4240 V voltage
3 - 5 seconds and visually check the indications of instruments.
6. By evenly rotation of output voltage regulator, decrease the voltage to 0 V. Release the key of
output voltage switch.
7. Disconnect the grounding plug of “aerial” type of device from aerial input on TV.
CHECKING OF ELECRIC RESISTANCE
Connect a generetor of 60 dB/µ 38.9 MHz to the pins 10 and 11 of selector. During this operation
pay attention that signal output must be connected to the pin 11, and the housing of cable - to pin
10. Switch on the service mode of TV set.
Bright line lower to record “VCO Fine 063”. Rotate a circuit L208 and wach if record “AFC Status
OK” appears. Press the “-” key on remote control and find the lower limit of intermediate
frequency (IF) range (the record OK ust disappear). After this by using the “+” key adjust ID by 5
digits from end og range. “VCO Coarse” should be equal 05. Disconect the IF cable from pins of
selector.
