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 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.
