Only qualified service technicians who are familiar with safety checks

and guidelines should perform service work. Before replacing parts,

disconnect power source to protect electrostatically sensitive parts. Do

not attempt to modify any circuit unless so recommended by the

manufacturer. When servicing the receiver, use an isolation transformer

between the line cord and power receptacle.

Use EXTREME CAUTION when servicing the high voltage circuits. To

discharge static high voltage, connect a 10K ohms resistor in series with a

test lead between the receiver ground and CRT anode lead. DO NOT lift

the CRT by the neck. Always wear shatterproof goggles when handling

the CRT to protect eyes in case of implosion.

Be aware of the instructions and procedures covering X-ray radiation. In

solid-state receivers and monitors, the CRT is the only potential source of

X-rays. Keep an accurate high voltage meter available at all times. Check

meter calibration periodically. Whenever servicing a receiver, check the

high voltage at various brightness levels to be sure it is regulating

properly. Keep high voltage at rated value, NO HIGHER. Excessive high

voltage may cause X-ray radiation or failure of associated components.

DO NOT depend on protection circuits to keep voltage at rated value.

When troubleshooting a receiver with excessive high voltage, avoid close

contact with the CRT. DO NOT operate the receiver longer than

necessary. To locate the cause of excessive high voltage, use a variable

AC transformer to regulate voltage. In present receivers, many electrical

and mechanical components have safety related characteristics which are

not detectable by visual inspection. Such components are identified by a

# on both the schematic and the parts list. For SAFETY, use only

equivalent replacement parts when replacing these components.

Perform a final SAFETY CHECK before returning receiver to customer.

Check repaired area for poorly soldered connections, and check entire

circuit board for solder splashes. Check board wiring for pinched wires or

wires contacting any high wattage resistors. Check that all control knobs,

shields, covers, grounds, and mounting hardware have been replaced. Be

sure to replace all insulators and restore proper lead dress.

Unplug the AC cord, connect a jumper across the plug prongs, and turn

the power switch on (if applicable). Use an ohmmeter to measure the

resistance between the jumped AC plug and any exposed metal cabinet

parts such as antenna screw heads, control shafts, or handle brackets.

Exposed metal parts with a return path should measure between 1M

ohms and 5.2M ohms. Parts without a return path must measure infinity.

Plug the AC cord directly into an AC outlet. DO NOT use an isolation

transformer. Use a 1500 ohms, 10W resistor in parallel with a .15µF

capacitor to connect between any exposed metal parts on the receiver and

a good earth ground. (See figure below.) Use an AC voltmeter with at

least 5000 ohms per volt sensitivity to measure the voltage across the

resistor. Check all exposed metal parts and measure voltage at each point.

Voltage measurements should not exceed .75VAC, 500µA. Any value

exceeding this limit constitutes a potential shock hazard and must be

corrected. If the AC plug is not polarized, reverse the AC plug and repeat

exposed metal part voltage measurement at each point.

The listing of any available replacement part herein in no case constitutes a recommendation, warranty, or guarantee by

SAMS Technical Publishing as to the quality and suitability of such replacement part. The numbers of the listed parts have

Apply 120VAC to set, turn set on, and adjust brightness and contrast to maximum.  Short

XRP-1 to XRP-2.  The set should shut down and then cycle on and off.  If the set does not

shut down and then cycle on and off, the shutdown circuoit requires repair.  To resume normal

operation remove the short from XRP-1 to XRP-2.
