2. Alignment & Adjustment
2-1 General Alignment Instructions
1. Usually, a color TV-VCR needs only slight touch-up
adjustment upon installation. Check the basic characteristics
such as height, horizontal and vertical sync and focus.
2. Observe the picture for good black and white details.
There should be objectionable color shading;
if color shading is present, demagnetize, perform purity and
convergence adjustments described below.
3. Use the specified test equipment or its equivalent.
4. Correct impedance matching is essential.
5. Avoid overload. Excessive signal from a sweep generator
might overload the front-end of the TV.
When inserting signal markers, do not allow the marker
generator to distort test results.
6. Connect the TV only to an AC power source with voltage and
frequency as specified on the backcover nameplate.
7. Do not attempt to connect or disconnect any wires while the
TV is turned on.
Make sure that the power cord is disconnected before
replacing any parts.
8. To protect against shock hazard, use an isolation
transformer.
2-2 Automatic Degaussing
A degaussing coil is mounted around the picture tube,
so that external degaussing after moving the TV should be
unnecessary. But the receiver must be properly degaussed
upon installation.
The degaussing coil operates for about 1 second after the
power is switched ON.
If the set is moved or turned in a different direction, the power
should be OFF for at least 10 minutes.
If the chassis or parts of the cabinet become magnetized,
poor color purity will result. If this happens, use an external
degaussing coil. Slowly move the degaussing coil around the
faceplate of the picture tube and the sides and front of the
receiver. Slowly withdraw the coil to a distance of about 6 feet
before turning power OFF.
If color shading persists, perform the following Color purity and
Convergence adjustments.
2-3 High Voltage Check
1. Connect a digital voltmeter to the second anode of the
picture tube.
2. Turn on the TV. Set the Brightness and Contrast controls to
minimum (zero beam current).
3. Adjust the Brightness and contrast controls to both extremes.
Ensure that the high voltage does not exceed 27 KV under
any conditions.
Caution : There is no high voltage adjustment on this chassis. The B+ power supply should be +123V
(with full color- bar input and normal picture level).

2-4 FOCUS Adjustment
1. Iput a black and white signal.
2. Adjust the tuning control for the clearest picture.
3. Adjust the FOCUS control for well defined scanning lines in
the center area of the screen.
2-5 Factory Adjustment
2-5-1 Service Mode
1. To enter the "Service Mode", Press the remotecontrol
keys in this sequence :
- If you do not have Factory remote-control
"Power Off" → "MUTE" → "1" → "8" → "2" → "Power On"
- If you have Factory remote-control
"Power On" → "DISPLAY" → "FACTORY"
