PREPARATION BEFORE CONFIRMATION
1. Using a Variac, apply AC input voltage: 120 ±2 VAC.
2. Turn the POWER switch ON.
3. Input a white signal and set the PICTURE and BRIGHTNESS controls
to maximum.
4. Confi rm that the voltage between C546 (+) or TP503 and ground is
more than 21.0 VDC.
HOLD-DOWN OPERATION CONFIRMATION
1. Connect the current meter between Pin 11 of the FBT (T505) and
the PWB land where Pin 11 would normally attach (See Figure 1 on
the next page).
the next page).
2. Input a dot signal and set PICTURE and BRIGHTNESS to minimum:
IABL = 1730 ± 100µA.
3. Confi rm the voltage of A Board TP-600 is 135 ± 1.5 VDC.
4. Connect the digital voltmeter and the DC power supply via Diode
1SS119 to C546 (+) and ground (See Figure 1 on next page).
5. Increase the DC power voltage gradually until the picture blanks out.
6. Turn DC power source off immediately.
7. Read the digital voltmeter indication (standard < 24.78 +0, -0.1 VDC).
8. Input a white signal and set PICTURE and BRIGHTNESS to
maximum: IABL = 1730 ± 100µA.
9. Repeat steps 4 to 7.
