When servicing, observe the original lead dress. If a short circuit is found, replace all parts which are overheated or damaged by the short circuit. After servicing ,see to it that all the protective devices such as insulation barriers ,insulation papers shields are properly installed .Confirm that the screws, parts and wiring which were removed in order to service are put in the original positions, or whether there are the portions which are deteriorated around the service places serviced or not. And be sure safety of that.

1. Before the failure diagnosis,
watch out for the electric shock and make sure that the power plug is disconnected
and then service.
2. After the power switches on, each load will automatically load voltage
220-240V or DC.
3. Before touching the PCB, please touch the earthling wire at first to avoid
that the PCB is broken by the static.
4. Exposed terminals, PC board, and rotating parts may cause injury and/or
electrical shock. To reduce the risk of electrical shock, disconnect power and
allow 60 seconds for capacitors to discharge before servicing.

Troubleshooting without display code
It makes sense to avoid exposure to electrical shock. While some sources are expected to have a possible dangerous impact, others of quite high potential are of limited current and are sometimes held in less regard.
