  • Page 2: Safety Precautions

    violation of law. 1. Safety precautions General guidelines An isolation transformer should always be used during the servicing of a receiver whose chassis is not isolated from AC power line. Use a transformer of adequate power rating as this protects the technician from accidents resulting in personal injuryfrom electrical shocks.
  • Page 3 Unplug the A.C. cord and connect a jumper between the two plug prongs.Measure the resistance between the jumpered AC plug and expose metallic parts such as screwheads, antenna terminals, control shafts, etc. If the exposed metallic part has a returnpath to the chassis, the reading should be between 240k and 5.2M .

  • Page 4: Service Notes

    Measure the high voltage. The high voltage should be 29.25 ± 1.25kV (for 27” and 32” models) and 31.25 ± 1.25kV (for 36” models). If the upper limit is out of tolerance,immediate service and correction is required to insure safe operation and to prevent the possibility of premature component failure.
  • Page 5 1. Put a small amount of solder on the board soldering pads. 2. Hold the chip component against the soldering pads with tweezers or with a miniature alligator clip and apply heat to the pad area with a 30 watt iron until solder flows. Do not apply heat for more than 3 seconds.
  • Page 6 4. Position the new Flat IC in place (apply the pins of the Flat IC to the soldering pads where the pins need to be soldered). Properly determine the positions of the soldering pads and pins by correctly aligning the polarity symbol 5.

X-Ray Protection Circuit Check& Adjustments This test must be performed as final check before the receiver is returned to the customer. If voltages are out of tolerance, immediate service and correction is required to insure safe operation and to prevent the possibility of premature componentfailure.

    5. Change to the next ID switch register with “CH” keys and repeat the same procedure as step 4. 6. When replacing a new EEPROM be sure to set the correct ID switch values for each model. 7. Once that all 3 registers are set with the correct address value, perform all of the remaining adjustments and servicing.
