Chassis Service Adjustment Procedures
All service adjustments are factory preset and should not require adjustment unless controls and/or
associated components are replaced.
Note: Connect the (-) lead of the voltmeter to the appropriate ground. Use heat sink when the HOT ground symbol
( ) is used. Otherwise, use COLD ground ( ) — Tuner shield.

MOMENTARILY CONNECT A JUMPER FOR ENTERING SERVICE MODE (TP8 to COLD GND)
140.0V B+ Voltage Confirmation
1. Set the Bright and the Picture to Minimum by
using the Picture Menu.
2. Connect the DVM between TPP17 (+ side) and cold
ground ( ).
3. Confirm that B+ voltage is 140.0V ± 1.5V. This
voltage supplies B+ to the Horizontal Output &
Flyback circuits.
Source Voltage Chart
120V AC line input. Set the Bright and the Picture to
Minimum by using the Picture Menu. Use cold ground
( ) for the (-) lead of the DVM.

High Voltage Check
1. Select an active TV channel and confirm that
horizontal is in sync.
2. Adjust Brightness and Picture using Picture Icon
menu so video just disappears.
3. Confirm B+ 140.0V is within limit.
4. Using a high voltage meter confirm that the High
Voltage is 31.0kV ± 1.0kV.
