Important Safety Notice
ANY PERSON ATTEMPTING TO SERVICE THIS CHASSIS MUST FAMILIARIZE HIMSELF WITH THE CHASSIS
AND BE AWARE OF THE NECESSARY SAFETY PRECAUTIONS TO BE USED WHEN SERVICING
ELECTRONIC EQUIPMENT CONTAINING HIGH VOLTAGES.
CAUTION: USE A SEPARATE ISOLATION TRANSFORMER FOR THIS UNIT WHEN SERVICING
REFER TO BACK COVER FOR IMPORTANT SAFETY GUIDELINGS
Important Safety Notice
Proper service and repair is important to the safe, reli able operatio n of all Dell Company** Equipment. The service
procedures recommended by Dell and described in this service manual are effective methods of performing
service operations. Some of these service operations require the use of tools specially designed for the purpose.
The special tools should be used when and as recomm ended.
It is important to note that this manual contains various CAUTIONS and NOTICES which should be carefully read
in order to minimize the risk of personal injury to service personnel. The possibility exists that improper service
methods may damage the equipment. It is also important to unde rst and that the se CAUTIONS and NOTICE S ARE
NOT EXHAUSTIVE. Dell could not possibly know, evaluate and advise the service trade of all conceivable ways in
which service might be done or of the possible hazardous consequences of each way. Consequently, Dell has not
undertaken any such broad evaluation. Accordingly, a servicer who uses a service procedure or tool which is not
recommended by Dell must first satisfy himself thoroughly that neither his safety nor the safe operation of the
equipment will be jeopardized by the service method selected.
* * Hereafter throughout this manual, Dell Comp any will be referred to as Dell.
WARNING
Use of substitute replacement parts, which do not have the same, specified safety characteristics may create
shock, fire, or other hazards.
Under no circumstances should the original desi gn be modified or altered with out written permissi on from Dell. Dell
assumes no liability, express or implied, arising out of any unauthorized modification of design. Servicer assumes
all liability.
FOR PRODUCTS CONTAINING LASER:
DANGER - Invisible laser radiation when open. AVOID DIRECT EXPOSURE TO BEAM.
CAUTION - Use of controls or adjustments or performance of procedure s othe r than those
CAUTION - The use of optical instruments with this product will increase eye hazard.
TO ENSURE THE CONTINUED RELIABILITY OF THIS PRODUCT, USE ONLY ORIGINAL
MANUFACT URER'S REPLACEMENT PARTS, WHICH ARE LISTED WITH THEIR PART
NUMBERS IN THE PARTS LIST SECTION OF THIS SERVICE MANUAL.
Take care during handling the LCD module with backlight unit
- Must mount the module using mounting holes arranged in four corners.
- Do not press on the panel, edge of the frame strongly or electric shock as this will result in damage to the
screen.
- Do not scratch or press on the panel with any sharp objects, such as pen cil or pen as this may result in
damage to the Panel.
- Protect the module from the ESD as it may damage the electronic circuit (C-MOS).
- Make certain that treatment person’s body is grounded throug h wristband.
specified herein may result in hazardous radiation exposure.
- Do not leave the module in high temperature and in areas of high humidity for a long time.
- Avoid contact with water as it may a short circuit within the module.
If the surface of panel becomes dirty, please wipe it off with a soft material. (Cleaning with a dirty or rough cloth
may damage the panel.)
