An isolation Transformer should always be used during the servicing of a receiver whose chassis is not isolated from the AC power line. Use a transformer of adequate power rating as this protects the technician from accidents resulting in personal injury from electrical shocks.

It will also protect the receiver and it's components from being damaged by accidental shorts of the circuitry that may be inadvertently introduced during the service operation.
If any fuse (or Fusible Resistor) in this monitor is blown, replace it with the same specified type.
When replacing a high wattage resistor (Oxide Metal Film Resistor, over 1W), keep the resistor 10mm away from PCB.

Adjustments

(1) Because this is not a hot chassis, it is not necessary to use an isolation transformer. However, the use of isolation transformer will help protect test equipment.
(2) Adjustments must be done in the correct order.
(3) The adjustments must be performed in the circumstance of 25±5°C of temperature and 65±10% of relative humidity if there is no specific designation.
(4) The input voltage of the receiver be must kept 110V, 60Hz when adjusting.
(5) The receiver must be operational for about 15 minutes prior to the adjustments.

After receiving 100% white pattern, the receiver must be operated prior to adjustment. (Or 8. White Pattern condition in EZ - Adjust)
2) Enter into White Pattern
- Press POWER ON Key on the Service Remote Control (S R/C)
- Enter the Ez - Adjust by pressing ADJ Key on the Service Remote Control (S R/C).
- Select 7. White Pattern using the CH +/- Key and press the Enter(Y) Key.
Display the 100% Full White Pattern.

[Set is activated HEAT-RUN without signal generator in this mode.]

(If you turn on a still screen more than 20 minutes (Especially Digital pattern (13 CH), Cross Hatch Pattern), an afterimage may occur in the black level part of the screen.)
