3-3 Other Adjustments
3-3-1 General
1. Usually, a color TV 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 no objectionable
color shading. If color shading is present,
perform the 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.
