5. Notes on service
  5. 1. Before service operation
    5. 1. 1. Lamp
1. The light source of the projector is a high-pressure mercury lamp.
2. The luminance of the lamp will decrease by duration of usage.
3. The lamp may burst with a loud sound or have its service life shortened because of shock, chipping, or degradation
     due to cumulative runtime.
4. The lamp life varies greatly depending on individual differences and usage conditions.
    In particular, frequent on/off switching of the power greatly deteriorate the lamp and affects the lamp life.
5. Continuous use for over one week will deteriorate the lamp. The degradation of the lamp due to continuous use can be
     reduced by using the [PROJECTOR SETUP] menu → [LAMP RELAY].
6. In rare cases, the lamps burst shortly after projection starts.
7. If the lamp bursts, gas contained inside of the lamp is released in the form of smoke.
8. The risk of bursting increases when the lamp is used beyond its replacement cycle. Make sure to replace the lamp unit reg
    Make sure to replace the lamp unit regularly.
    It is recommended that you store the Replacement lamp unit as a contingency.
Note
・Panasonic takes no responsibility for any damage or malfunction of the product
  resulting from use of lamp units which are not manufactured by Panasonic. Use only specified lamp units.
・Please be sure to read the warnings and notices on the lamp that is described in the Operating Instructions.
  "Read this first!",  "Precautions for use", "Maintenance/replacement"
    5. 1. 2. Air filter unit
1. Make sure that the air filter unit is properly attached before using the projector. If it is not properly attached, 
    the projector will suck in dirt and dust causing a malfunction.
2. The cleaning and replacement cycle of the air filter unit varies  depending on the usage environment.
3. Do not use water when cleaning the air filter. Washing with water may decrease the dust absorption capability.
4. The air filter for replacement is an optional accessory (service part).
    Air filter is provided for the optional Replacement lamp unit.  (ET‑LAD120 : 1 pc, ET‑LAD120W : 2 pcs)
    5. 1. 3. Lithium battery
1. The lithium battery is used for the internal clock in the A-P.C.Board. So when it consumed it must be replaced.
2. After replacing the lithium battery, set the "Date and Time" on the sub-menu which in main menu "projector set up".
Replacement lamp unit : ET-LAD120 (1 pc) / ET-LAD120W (2 pcs)
Attention
Air filter unit : TMZX5209 (Two pieces are equipped in projector)
Lithium battery : CR2032
* Use only specified lithium battery.
* Used battery must be scrapped according to the instruction.
  5. 2. Service

・ Mechanical shutter
    5. 2. 2. Repair
1. Since this projector is very strong light output, when checking the projection screen, please UV protection glasses
     and select to "single" lamp mode.  If the projection distance is short, please pay particular attention.
2. When removing a top cover and carrying out check or adjustment, a strong light has leaked from the optical block.
    Please take the use of UV protection glasses and means of the shading.
3. Before repair, make sure to turn off the main power and disconnect the power plug from the power outlet.
* When replacing the print board, the internal electrical parts can be broken by the static electricity of clothes or human
  body. Please take care in static electricity, use an antistatic wrist strap or wear the anti-static electricity gloves.
4. After repair, please check the gradation (10step or the gray scale) test pattern and moving image.
    Also, please check that it is normal on a self check screen.
    5. 2. 3. Interlock detection
Detection by the connector on the rear cover.
Power will not turn on, unless the connector R33 in a lamp cover is inserted in the main body side. 
    5. 2. 4. Replacement of printed circuit board
1. When the replacement of A-P.C.Board (assembly) is needed, back up the memory information such as adjustment
    data from the old board to PC with the service soft. Then transfer this data to the new A-P.C.Board.
    For more information refer to the SECTION 3 "Adjustment".
*
Down load the adjustment software from Projector service web site.
* If you cannot transfer the data that uses the service software, remove IC3508/IC3518 from the original board 
and mount them on the new board.
2. When A-P.C.Board is replaced, the MAC address of wired LAN will be changed. Explain it to the customers in advance.
3. When replacing the printed circuit board, update each firmware to the latest version.

  5. 3. Replacement of consumable parts
・Set the MAIN POWER switch to "OFF" and disconnect the power plug from the power outlet.
・Do not replace the lamp unit when it is high temperature. (Wait at least one hour after use.)
    5. 3. 1. When to replace the lamp unit
1. The estimated duration before replacement is 3 000 hours, but the lamp may go off before 3 000 hours has
    elapsed depending on individual lamp characteristics, usage conditions, and the installation environment.
    It is recommended that the Replacement lamp unit be prepared earlier.
2. When comes time to replace the lamp, will announce with an onscreen display and a lamp indicator.
    To predict when to replace the lamp, check the lamp runtime displayed in [LAMP1] and [LAMP2] in [STATUS].
3. If you continue to use the lamp unit after 3 000 hours has elapsed, the lamp turns off automatically after 
    approximately 10 minutes, as it will cause malfunction of the projector.
    If the runtime of both of two lamp unit bulbs exceeds 3 000 hours, the power will be switch off after approximately
    10 minutes.
・3 000 hours is only the target for replacement and not the warranty time.
    5. 3. 2. Calculation formula of lamp runtime
The lamp runtime that is displayed in the [STATUS] is real time. 
The following conversion is required to calculate the rough estimate for lamp replacement.
    5. 3. 3. Notes on the replacement of the lamp unit
1. Since the luminous lamp is made of glass, it may burst if dropped or hit with a hard object. Handle with care.
2. When replacing the lamp unit, be sure to hold it by the handle because its surface is pointed and its shape is protruded.
3. When the projector is mounted on the ceiling, do not conduct work while your face is near the lamp unit.
4. Do not remove or loosen the screws other than specified ones when replacing the lamp unit.
Notes
・When you replace the lamp unit with new one, the projector resets the runtime of the lamp unit automatically.
・When replacing the lamp unit, replace the corresponding air filter.
   (Air filter is provided for the optional accessory of replacement lamp unit.)
