1.  The display unit of this projector comprises three LCD panels. Although an LCD panel is a product of high-precision tech-

nology, some of the pixels on the image may be missing or constantly lit. Please note that this is not a failure.

2.  Displaying a still image for a longer time may result in an after-image on the LCD panels. If this happens, display the all 

white screen in the test pattern for an hour or more.

1. The light source of the projector is a high-pressure mercury lamp.
2. A high-pressure mercury lamp has the following characteristics.
  • The luminance of the lamp will decrease by duration of usage.
  •  The lamp may burst with a loud sound or have its service life shortened because of shock, chipping, or degradation due to 

cumulative runtime.

  •  The lamp life varies greatly depending on individual differences and usage conditions. In particular, continuous use for 12 

hours or more and frequent off/on switching of the power greatly deteriorate the lamp and affects the lamp life.

  • In rare cases, the lamps burst shortly after projection starts.
  •  The risk of bursting increases when the lamp is used beyond its replacement cycle. Make sure to replace the lamp unit 

regularly.

   (Refer to items “When to replace the lamp unit”, “How to replace the lamp unit”)
  • If the lamp bursts, gas contained inside of the lamp is released in the form of smoke.

 • 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.

Attention 

*   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"

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 us-

age environment.

The basic service policy is shown below.

Repair contents

Applied parts

Block replacement 
P.C.Board replacement

 

- Lighting block (* Specified components are replaced)

 

- Optical Block (PT-VW535N/VX605N)

- Optical Block+Projection lens+Lens shift unit (PT-VZ575N)

 

- [P]-P.C.Board (Specified components are replaced)

 

- [BQ]-P.C.Board

 

- Iris unit

Replaced by discrete components

Other electrical parts and mechanism parts

1.  Since very strong light is leakage from the surroundings of optical block, when checking or adjusting the projector with top 

cabinet removal, ware the UV protection glasses to protect the UV light. 

2. Before repairing, 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.

3. After repairing, please check the gradation (10step or the gray scale) test pattern or moving image.
  Also, please check that it is normal on a self check screen.

The lamp cover switch detects whether the lamp cover is mounted securely.
When the lamp cover is mounted securely, the interlock switch (K8S) on the [A]-P.C.Board turns on.

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 software. Then transfer this data to the new [A]-P.C.Board.

 For more information refer to the SECTION 3 "Adjustment".
  * Down load the service software from Projector service web site.
  * The several types of adjustment data have been stored in the memory ICs listed below.

IC1391

User setting data, Service adjustment data, Model No. 
Serial No.

IC303

Gamma data, Color shading correction data

2.  When [A]-P.C.Board is replaced, the MAC address of wired LAN and wireless LAN will be changed. Explain it to the cus-

tomers in advance.

Interlock switch (K8S)

[Attention] •  When replacing the consumable parts, please make sure that the power cable is disconnected from the outlet.

The lamp unit is a consumable component. Since its brightness gradually decreases over time, it is necessary to replace the 
lamp unit regularly. The estimated duration before replacement is 5 000 hours, but the lamp may go off before reaching to 
5000 hours, depending on the characteristics of the individual lamp, usage conditions, and the installation environment. It is 

recommended that the Replacement Lamp Unit be prepared earlier.

Over 4 800 hours

The message is displayed for 30 seconds. Pressing 
any button on the control panel or remote control 
within 30 seconds will clear the message.

The indicator lights in red even during the 
standby mode.

Over 5 000 hours

The message remains displayed until you press any 
button.

If you continue to use the lamp unit after 5 000 hours has elapsed, the lamp turns off automatically after approximately 10 
minutes, as it may cause malfunction of the projector.

• To predict when to replace the lamp, check the lamp runtime displayed at [STATUS] - [RUNTIME] in [PROJECTOR SETUP].
• 5 000 hours is only the target for replacement and not the warranty time.

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.

= “Lamp runtime of [NORMAL]” + “Lamp runtime of [ECO]” × 5/7

There are 2 types of optical block, named R-type and L-type.
When replacing the optical block, check the printed marker on the flat cable of the G-LCD panel and use the same type of the 
optical block. If not used the same type, you will find the color shading or wrong white balance picture on the screen. 

• GL => Use L-type optical block

• GR => Use R-type optical block
