Safety measures and Attention

4.Safety measures and Attention

4.1. Observation and measures carefully： When in repair service, should pay attention to these safety measures and the

description

of the service menu.

4.2.Preparation: The preparation for repair in a defective PDP is necessary, ex：stable working table, repair tools, measuring equipments, replace parts etc.

4.3.Pay attention to electrical shock: Because the PDP is using the AC power source, and the power board contents high voltage, so to preventing the high voltage shock is necessary. Such as, using an isolated transformer, plastic glove, charged components should be discharged first. The high voltage is supplied to inferior components, so when repair the PDP should pay more attentions.

4.4.Using the specified components: Some components provide fire-resist and endure high-voltage. So when replace these parts, should use the same characteristic components. So when replace a component should according to the BOM form for a assigned component.

4.5.Stable the components and recovery the wiring: Some components are using isolated sleeve or adhesive tape to isolate from the electric board. Moreover the interior wiring should be arranged again to prevent the interference from given out heat components and high voltage components .So after repairing, should recover the same layout of the PDP.

4.6.Integrity of the electric circuit : Use the specified components to replace the defective parts. Under any

circumstance，do not try to modified the electric circuit .

4.7.Safety check after repairing： After repairing, should check the screws and the wiring condition. Checking the

quality of repairing components. The insulation test of the metal component, power cord to make sure the safety of repairing.
