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 Q801’s heat sink when the HOT

ground symbol ( ) is used. Otherwise, use COLD ground (

) — Tuner shield, IC2301’s heat sink (See Fig. 50)

MOMENTARILY CONNECT A JUMPER FOR ENTERING SERVICE MODE (FA1 to FA2)

140.0V B2+ Voltage Check

Set the Bright and Picture to Minimum by using
the Picture Menu.

Connect the DVM on TPP17 (D-Board) and cold

ground (

Confirm that B2+ voltage is 144.0V ± 1.5V. This
voltage supplies B2+ 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

(

) or

Hot ( ) ground for the (-) lead of the DVM as needed.

High Voltage Check

Select an active TV channel and confirm that
horizontal is in sync.

Adjust Brightness and Picture using Picture Icon
menu so video just disappears.

Confirm B2+ 144 ± 1.5V is within limit.

Using a high voltage meter confirm that the High
Voltage is 31.0kV ± 1.0kV.
