MAIN CBA REPLACEMENT
Note: The
TV/Tuner Unit includes the Main C.B.A.
CAUTION: Be sure to make a note of the CURRENT LAMP
value (value A) in Service Mode (1/3):
- LAMP OPERATION TIME is stored in EEPROM on the Main C.B.A. Therefore, before removing the Main C.B.A. or the TV/Tuner Unit at the user’s location, make a note of the CURRENT LAMP value (value A) in Service Mode (1/3).
- Then, after installing the new Main C.B.A. or the TV/Tuner Unit at the user’s location, set the CURRENT LAMP value to the original value (value A) in Service Mode. Otherwise, OSD and LED Lamp replacement indications will be displayed at the wrong time.
In case if it is
impossible to make a note of the CURRENT LAMP value because of a defective Main C.B.A., ask the
customer their daily average use and the approximate age of the current Lamp. Then, calculate the
CURRENT LAMP value as follows and make a note. {Daily average use: Hours}
X {Approx Age: Days} = {Current Lamp
Hours}
The TOTAL value can be set to the original
value in Service Mode (2/3) by similar method:
Before removing the Main C.B.A. at the
user’s location, make a note of the TOTAL value in Service Mode (2/3).
Then,
after installing the new Main C.B.A. at the user’s location, set the TOTAL
value to the original value in Service Mode.
WHEN RE-INSTALLING MAIN CBA OR THE TV TUNER INTO THE UNIT
CAUTION:
- Set CURRENT LAMP value to original value as follows.
- Select CURRENT LAMP in Service Mode (1/3).
- Press the VOLUME UP/DOWN key on the remote to change to the original value (value A) that was noted before removing the Main C.B.A. or the TV/Tuner Unit at the user’s location.
LAMP REPLACEMENT { LAMP UNIT: TY-LA1000].
The Lamp Unit
(TY-LA1000) is not supplied as a replacement part. It is sold separately. To
purchase a replacement, call the Panasonic accessory department
Lamp Time Reset
Procedure:
- Be sure to reset the Lamp time to "0" after replacing the new Lamp.
- Plug in the AC Cord, and turn on the power by pressing the POWER button.
- Press and hold the VOLUME DOWN button on the unit and the SPLIT key on the remote together for over 5 seconds in power on condition.
- When the reset is finished, the display appears and the LAMP LED goes out.
The unit will detect when the Lamp’s end of
life is approaching and the following message will be displayed. And the LAMP
indicator light will be lit when the Lamp’s end of life is approaching.
Influences of frequent lighting, continuous
light use for over 24 hours, the number of times lit, the length of time
between lightings, etc. may shorten lamp life. (Because of this, we recommend
having a replacement lamp on hand.)
- The high-pressure lamp could explode if not properly handled and lamp fragments could cause injury.
- Because the temperature of the lamp unit is elevated immediately after its use, touching it may cause burns. Allow the lamp to cool before handling or replacing the lamp unit.
- Wear gloves and safety eyeglasses when replacing the lamp unit.
- If replacement of the lamp unit becomes necessary during the operation of the TV, follow the procedure to turn off the power and wait until the lamp unit cools completely.
Cautions for Lamp
Unit Replacement:
- Do not disassemble the Lamp.
- The lamp may be hot. Be careful when handling. Wear gloves.
- Under no circumstance should you touch the actual bulb. At this high operating temperature the natural oil on your finger can cause the glass to weaken where touched and the bulb can crack or explode.
LAMP REPLACEMENT PROCEDURE
- Press the POWER button on the remote to turn off the power.
- Wait for about 1 minute until the cooling fan stops. {Note: The lamp cooling fan will continue to operate for about 1 minute after the power is turned off. Do not unplug the AC Cord from the outlet until the fan has stopped. Avoid interrupting the power by using circuit breakers or switchable power strips.}
- After the cooling fan has stopped, unplug the AC Cord from the outlet. {Note: Wait more than one hour before replacing the lamp.}
[ Forced cooling
function ]
If you need to
replace the lamp more urgently:
- The Projection display has a forced cooling feature. After the POWER button is turned OFF, and sometime during about the first minute of the normal cooling fan operation, press the VOLUME UP button on the unit and CH UP key on the remote at the same time for more than 5 seconds. The cooling fan will operate for about 10 minutes. (LAMP LED will flash 5 times every 5 second and POWER LED will flash red for 10 minutes.)
- Remove the Front Cover Unit from the latches.
- Remove the Lamp Cover by loosening the Screw.
- Loosen the Screw on the Lamp. Then, pull the Lamp. {Note: Because the Lamp may still be hot, use caution when handling.}
- Install the new Lamp, and tighten the Screw.
- Install the Lamp Cover securely, and tighten the Screw.
- Install the Front Cover Unit. {Note: After replacing the Lamp, use caution to reset the Lamp time.}
