Static Electricity Precautions - Samsung PS42B430P2WXXH Service Manual

1-3 Static Electricity Precautions

1. Some semi-conductive ("solid state") devices are
vulnerable to static electricity. These devices are known
as ESD. ESD includes the integrated circuit and the field
effect transistor. To avoid any materials damage from
electrostatic shock, follow the instructions described
below.
2. Remove any static electricity from your body by
connecting the earth ground before handling any
semi-conductive parts or assemblies. Alternatively,
wear a dischargeable wrist-belt. (Make sure to remove
any static electricity before connecting the power source
- this is a safety instruction for avoiding electric shock)
3. Remove the ESD assembly and place it on a conductive
surface such as aluminum foil to prevent accumulating
static electricity.
4. Do not use any Freon-based chemicals. Such chemicals
will generate static electricity that causes damage to the
ESD.
5. Use only grounded-tip irons for soldering purposes.

6. Use only anti-static solder removal devices. Most solder
removal devices do not support an anti-static feature.
A solder removal device without an anti-static feature
can store enough static electricity to cause damage to
the ESD.
7. Do not remove the ESD from the protective box until the
replacement is ready. Most ESD replacements are
covered with lead, which will cause a short to the entire
unit due to the conductive foam, aluminum foil or other
conductive materials.
8. Remove the protective material from the ESD
replacement lead immediately after connecting it to the
chassis or circuit assembly.
9. Take extreme caution in handling any uncovered ESD
replacements. Actions such as brushing clothes or lifting
your leg from the carpet floor can generate enough static
electricity to damage the ESD.
CAUTION
These servicing instructions are for use by qualified
service personnel only.
To reduce the risk of electric shock do not perform any
servicing other than that contained in the operating
instructions unless you are qualified to do so.
