pin 1 on D-Board
H.V. measurement
4. Connect a H.V. meter (static type, class 0.1) with high voltage
leads to high voltage distributor on FBT.
DVM and power supply connection
5. Connect the 15 ~ 25 V DC variable power supply positive lead to
D34 or IC802 pin 2 (D Board) and negative lead to heat sink of
Q551 or D825
Procedures:
1. Apply a NTSC white pattern.
2. Turn PTV ON.
3. Adjust the picture or brightness controls so that the DVM reads
12.4 ± 0.4 volts.
4. Increase the variable power supply until set turns off. The set
should turn off at 12.4 ± 0.4 volts (DVM) and high voltage less than
36.4kV.
5. If the DVM reading is other than 12.4 ± 0.4 volts, readjust picture
or brightness control and repeat steps 3.
6. Turn off the variable supply and confirm that the set will turn on
with the remote control.
