Replace RV8001, RV8002 and RV8003 (Board provided with RV8003) with the
same value:
HV project adjust and inspection

HV project adjust and inspection
1. Turn RV8001 and RV8003 (only applicable when RV8003 is used in the circuit)
fully counter-clockwise.
2. Turn set on with black video signal then adjust RV8002 slowly to obtain
35.5kV ± 0.2kV.
3. Case 1 (Board provided with RV8003):
- Turn RV8001 (coarse adjust) clockwise slowly until hold down operation
initially activates.
- Turn the set off and turn back RV8001 approximately 1/16 of a turn, then turn
the set back on.
- Turn RV8003 (fine adjust) slowly clockwise until hold down operation initially
activates.
Case 2 (Board NOT provided with RV8003):
- Turn RV8001 clockwise slowly until hold down operation initially activates.
- Turn RV8001 clockwise slowly until hold down operation initially activates.
5. Adjust RV8002 clockwise, then turn the set on. Change video to white field then
slowly turn RV8002 counter-clockwise to get 35.0 ± 0.2kv. Confirm set does
NOT TURN OFF at this condition. If yes, then repeat from step 1 again.
NOT TURN OFF at this condition. If yes, then repeat from step 1 again.

Confirm +B, Vd and check hold-down on the D board video with no signal (standard
reset mode) as follows:
1. Confirm +B across C6544 to make sure that it is 135.3 ± 1 Vdc.
2. Confirm Vd at pin 2 CN5506 or at TP-Vd for 4.3V < Vd < 4.65 Vdc.
3. Apply 5.5 ± 0.3 Vdc at pin 2 of CN5506, then confirm that set holds down.

3. Apply 5.5 ± 0.3 Vdc at pin 2 of CN5506, then confirm that set holds down.
If all adjustments are complete, then seal and secure RV8001, RV8002 and
RV8003 (boards using RV8003) with epoxy to prevent any possible
misadjustment by non-trained technical service.
