Remove 6 push-on type knobs from side of cabinet. 2. Remove 3 metal screws holding front trim and remove trim. 3. Bend 2 tabs at top of safety glass up and remove safety glass. 4. Remove 6 metal screws and remove rear cover. 5. Remove speaker leads. 6. Remove 1 metal screw holding chassis to brace at top. 7. Place receiver front down on a pad. 8. Remove 3 chassis screws from bottom. 9. Lift cabinet off of chassis. 10. Remove 2 speaker nuts and remove speaker. MODEL 14-S-7052 CHASSIS KCS102B SERVICING IN THE FIELD TUNER OSCILLATOR ADJUSTMENTS Touch-up adjustments of the VHF tuner oscillator circuit may be accomplished by removing the channel selector and fine tuning knobs. PICTURE TUBE SAFETY GLASS CLEANING 1. Remove 3 metal screws from bottom holding front trim and remove trim. 2. Bend up tabs at top of safety glass and remove safety glass. 3. Caution: Use only a soft cloth and water to clean safety glass. FOCUS Adjust Ion trap for best focus consistent with maximum brightness. HORIZONTAL OSCILLATOR FIELD ADJUSTMENT The horizontal frequency coil is located on the control panel of the chassis and is used as the horizontal hold control. Adjust the horizontal hold until the picture synchronizes horizontally. FUSES One fuse is used for horlz. sweep circuit protection. (For location see tube placement chart.) CENTERING Centering is accomplished mechanically by adjusting two magnetic rings around the neck of the picture tube. Rotate the two rings around the neck of the tube until the picture Is properly centered. i o i m JS -* a K N 09 O k.s HOWARD W. SAMS AC voltage measured at 1,000 ohms per volt. 4. 2.

VIDEO IF ALIGNMENT Connect a 1000 ohm potentiometer across a 7. 5 volt bias battery (capable of an appreciable current drain). Connect the potentiometer to point and the positive lead of the battery to chassis. Set the potentiometer arm to provide -3. 5 volts at point , Connect the synchronized sweep voltage from the sweep generator to the horizontal input of the oscilloscope for horizontal deflection.
