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.
