SAFETY CHECK-OUT
After correcting the original service problem, perform the following safety checks before releasing the set to the customer: 1. Check the area of your repair for unsoldered or poorly-soldered connections. Check the entire board surface for solder splashes and bridges. 2. Check the interboard wiring to ensure that no wires are "pinched" or contact high-wattage resistors. 3. Check that all control knobs, shields, covers, ground straps, and mounting hardware have been replaced. Be absolutely certain that you have replaced all the insulators. 4. Look for unauthorized replacement parts, particularly transistors, that were installed during a previous repair. Point them out to the customer and recommend their replacement. 5. Look for parts which, though functioning, show obvious signs of deterioration. Point them out to the customer and recommend their replacement. 6. Check the line cords for cracks and abrasion. Recommend the replacement of any such line cord to the customer. 7. Check the B+ and HV to see if they are specified values. Make sure your instruments are accurate; be suspicious of your HV meter if sets always have low HV. 8. Check the antenna terminals, metal trim, "metallized" knobs, screws, and all other exposed metal parts for AC Leakage. Check leakage as described below.
To Exposed Metal Parts on Set
LEAKAGE TEST
The AC leakage from any exposed metal part to earth ground and from all exposed metal parts to any exposed metal part having a return to chassis, must not exceed 0.5 mA (500 microamperes). Leakage current can be measured by any one of three methods. 1. A commercial leakage tester, such as the Simpson 229 or RCA WT-540A. Follow the manufacturers' instructions to use these instruments. 2. A battery-operated AC milliammeter. The Data Precision 245 digital multimeter is suitable for this job. 3. Measuring the voltage drop across a resistor by means of a VOM or battery-operated AC voltmeter. The "limit" indication is 0.75 V, so analog meters must have an accurate lowvoltage scale. The Simpson 250 and Sanwa SH-63Trd are examples of a passive VOMs that are suitable. Nearly all battery operated digital multimeters that have a 2 V AC range are suitable. (See Fig. A)

The SCREEN settings allow you to degauss (demagnetize) the monitor manually and adjust the picture quality by controlling the moire and landing. · If the color is not uniform or picture is fuzzy, degauss the monitor (DEGAUSS). · If elliptical or wavy patterns appear on the screen, cancel the moire (CANCEL MOIRE). · If the color is irregular at the corners of the screen, adjust the landing (LANDING) (CPD-G520 only). The monitor is automatically demagnetized (degaussed) when the power is turned on. The screen is degaussed for about 2 seconds. If a second degauss cycle is needed, allow a minimum interval of 20 minutes for the best result. The CANCEL MOIRE setting is stored in memory for the current input signal. All other settings are stored in memory for all input signals.

Technical Features
Preset and user modes
When the monitor receives an input signal, it automatically matches the signal to one of the factory preset modes stored in the monitor's memory to provide a high quality picture at the center of the screen. (See Appendix for a list of the factory preset modes.) For input signals that do not match one of the factory preset modes, the digital Multiscan technology of this monitor ensures that a clear picture appears on the screen for any timing in the monitor's frequency range (horizontal: 30 130 kHz (CPDG520), 30 110 kHz (CPD-G420), vertical: 48 170 Hz). If the picture is adjusted, the adjustment data is stored as a user mode and automatically recalled whenever the same input signal is received.
Troubleshooting
Before contacting technical support, refer to this section.
This indicates that the input signal is not supported by the monitor's specifications.

2 Using a thumb pull up the rubber cap firmly in the direction indicated by the arrow b.
· HOW TO HANDLE AN ANODE-CAP
1 Don't scratch the surface of anode-caps with sharp shaped material! 2 Don't press the rubber hardly not to damage inside of anodecaps! A material fitting called as shatter-hook terminal is built in the rubber. 3 Don't turn the foot of rubber over hardly! The shatter-hook terminal will stick out or damage the rubber.
3 When one side of the rubber cap is separated from the anode button, the anode-cap can be removed by turning up the rubber cap and pulling up it in the direction of the arrow c.
