TECHNICAL CAUTIONS

High Voltage Limiter Circuit Operation Check and Overvoltage Protection Circuit Operation Check

Adjustment Preparation
1. Connect a High Voltage Voltmeter between CPT Anode terminal (Anode capside) and Ground.
2. Set the AC input voltage to 120±3V.
3. Receive Circle Pattern or Broadcast Signal and set “BRIGHTNESS” and “CONTRAST” to maximum. Adjust the

SCREEN VR so that Beam Current is I

B

±0.1mA. (The voltage at ABL terminal (C706) should be 12V or less.)

Adjustment Procedure
1. Check that the normal High Voltage and +B Voltage as below.

2. Connect a 10K

Ω

1/8W resistor to both ends of D703 and check that power is turned off.

3. Disconnect the AC plug and remove the 10k

Ω

resistor.
