AOC 27B35HM Dissambly Instruction page 3

General Safety Instructions
1. General Guidelines
When servicing, observe the original lead dress. If a short circuit is found, replace all parts which have
been 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.
After servicing, make the following leakage current checks to prevent the customer from being exposed to
shock hazards.
1) Leakage Current Cold Check
2) Leakage Current Hot Check
3) Prevention of Electro Static Discharge (ESD) to Electrostatically Sensitive
2. Important Notice
2-1. Follow the regulations and warnings
Most important thing is to list up the potential hazard or risk for the service personnel to open the units
and disassemble the units. For example, we need to describe properly how to avoid the possibility to get
electrical shock from the live power supply or charged electrical parts (even the power is off).
2-2. Be careful to the electrical shock
To prevent damage which might result in electric shock or fire, do not expose this TV set to rain or excessive
moisture. This TV must not be exposed to dripping or splashing water, and objects filled with liquid, such
as vases, must not be placed on top of or above the TV.
2-3. Electro static discharge (ESD)
Some semiconductor (solid state) devices can be damaged easily by static electricity. Such components
commonly are called Electrostatically Sensitive (ES) Devices. The following techniques should be used to
help reduce the incidence of component damage caused by electros static discharge (ESD).
2-4. About lead free solder (PbF)
This product is manufactured using lead-free solder as a part of a movement within the consumer products
industry at large to be environmentally responsible. Lead-free solder must be used in the servicing and
repairing of this product.
2-5. Use the genewing parts (specified parts)
Special parts which have purposes of fire retardant (resistors), high-quality sound (capacitors), low noise
(resistors), etc. are used.
When replacing any of components, be sure to use only manufacture's specified parts shown in the parts
list.
