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.
4. Service notes
NOTE
These components are affixed with glue. Be careful not to break or damage any foil under the
