1. Precautions

1-1. Precautions for the Service

●

Use the standard parts when replacing the electric parts.

– Confirm the model name, rated voltage, rated current of the electric parts.

●

Repair the disconnection of HARNESS securely when repairing the break down.

– If there is any connection error, it causes an abnormal noise and incorrect operation.

●

In case that you assemble or disassemble the products with laying it on the side, do work on the work cloth.

– If not, the exterior of products can be scratched.

●

Remove dust and foreign materials from harness, connection part, and inspection part thoroughly when repairing

the break down.

– It protects the danger of fire such as tracking and short.

●

Check the assembly status of parts after repairing the break down.

– It should be same as the status before repairing.

1-2. Precautions for the Static Electricity and PL

●

As the PCB power terminal has a weakness for the static electricity, pay attention to it during the repair and measurement.

– Work with insulation gloves during the repair and measurement of PCB.

●

Check the distance between the product and the other electronic appliances such as TV, video, and audio.

It should be over 2m.

– If not, it causes a bad picture quality or a noise.

●

Repairing the products by consumer should be strictly prohibited.

– There is a danger of electric shock or fire due to incorrect disassembly.

1-3. Precautions for the Safety

●

Do not pull any electric wires and do not touch an auxiliary power switch with a wet hand.

– There is a danger of electric shock or fire.

●

In case any wire or power plug has been damaged, replace it to eliminate any possible danger.

●

Do not bend the power cord by force and do not put any heavy object on the power cord.

– There is a danger of electric shock or fire.

●

Do not use multi socket.

– There is a danger of electric shock or fire.

●

Ground the product if necessary.

– Be sure to ground the product if there is any danger of electric leakage due to water or moisture.

●

Be sure to turn off the auxiliary power switch or pull out the power plug during replacement or repair of electric parts.

– There is a danger of electric shock.
