- Usually, a color LED TV needs only slight touch-up adjustment upon installation.
- Check the basic characteristics such as height, horizontal and vertical sync. Use the specified test equipment or its equivalent.
- Correct impedance matching is essential.
- 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 result.
- Connect the TV only to an AC power source with voltage and frequency as specified on the backcover nameplate.
- Do not attempt to connect or disconnect any wire while the TV is turned on. Make sure that the power cord is disconnected before replacing any parts.
- To protect against shock hazard, use an isolation transformer.
