1.2 Notes
Notes on Safe Handling of the LCD panel and during service
The work procedures shown with the Note indication are important for ensuring the
safety of the product and the servicing work. Be sure to follow these instructions.
• Before starting the work, secure a sufficient working space.
• At all times other than when adjusting and checking the product, be sure to turn OFF
the POWER Button and disconnect the power cable from the power source of the TV
during servicing.
• To prevent electric shock and breakage of PC board, start the servicing work at least 30
seconds after the main power has been turned off. Especially when installing and
removing the power board, start servicing at least 2 minutes after the main power has
been turned off.
• While the main power is on, do not touch any parts or circuits other than the ones
specified. If any connection other than the one specified is made between the measuring
Hisense Confidential
- 7 -

LCD TV Service Manual
equipment and the high voltage power supply block, it can result in electric shock or
activation of the leakage-detection circuit breaker.
• When installing the LCD module in, and removing it from the packing carton, be sure
to have at least two persons perform the work.
• When the surface of the panel comes into contact with the cushioning materials, be
sure to confirm that there is no foreign matter on top of the cushioning materials before
the surface of the panel comes into contact with the cushioning materials. Failure to
observe this precaution may result in, the surface of the panel being scratched by foreign
matter.
• When handling the circuit board, be sure to remove static electricity from your body
before handling the circuit board.
• Be sure to handle the circuit board by holding the large parts as the heat sink or
transformer. Failure to observe this precaution may result in the occurrence of an
abnormality in the soldered areas.
• Do not stack the circuit boards. Failure to observe this precaution may result in
problems resulting from scratches on the parts, the deformation of parts, and
short-circuits due to residual electric charge.
• Routing of the wires and fixing them in position must be done in accordance with the
original routing and fixing configuration when servicing is completed. All the wires are
routed far away from the areas that become hot (such as the heat sink). These wires are
fixed in position with the wire clamps so that the wires do not move, thereby ensuring
Hisense Confidential
- 8 -

LCD TV Service Manual
that they are not damaged and their materials do not deteriorate over long periods of time.
Therefore, route the cables and fix the cables to the original position and states using the
wire clamps.
• Perform a safety check when servicing is completed. Verify that the peripherals of the
serviced points have not undergone any deterioration during servicing. Also verify that
the screws, parts and cables removed for servicing purposes have all been returned to
their proper locations in accordance with the original setup.
The lightning flash with arrowhead symbol, within an equilateral
triangle is intended to alert the user to the presence of uninsulated
dangerous voltage within the products enclosure that may be of sufficient magnitude to
constitute a risk of electric shock.
The exclamation point within an equilateral triangle is intended to alert
the user to the presence of important operating and maintenance (servicing)
instructions in the literature accompanying the set.
