Disclaimer

The following procedures work with many Sony liquid crystal rear-projection TVs, but not necessarily all of them. I have only tested the first procedure on my own KDF-55WF655. Accessing the service menu could render your TV non-functional if you make incorrect entries, so it should only be done with extreme caution. Proceed at your own risk.


General service menu information

Enter Service Menu = <DISPLAY> <5> <Volume +> <POWER>
Exit Service Menu = <Power>
Menu Next = <1>
Menu Previous = <4>
Category Next = <2>
Category Previous = <5>
Adjust Up = <3>
Adjust Down = <6>
Save New Settings = <MUTE> <ENTER>
Restore Factory Defaults = <8> <ENTER>

2004-2005 3LCD models: WE, WF655, XS955, and A20 (not A10)

1. To access the service menu, with the TV off, press the following buttons on the remote control sequentially in rapid succession (note: if the TV is already on, you can start by turning the power off, but then you should enter the full 4-button sequence within about 3 seconds to avoid a lamp restart): <DISPLAY> <5> <Volume +> <POWER>


2. Press <JUMP> until the PANEL service menu displays (typically 3 presses).

3. Press <2> until the OPTION_E category appears (typically 9 presses). The "LampTM" (lamp power-on time in hours) and "LampCT" (lamp on/off cycles) entries are in the first item in the OPTION_E category. If they are not displayed, press <1> repeatedly until they do.

The display should look as follows:
PANEL NVM OK 9 OPTION_E
0 LAMP 0 Diff 1
LampTM #### LampCT ####

To reset the LampTM counter, press <3> <MUTING> <ENTER>.
WRI-EXE will be displayed in red text for awhile, followed by resetting to “0”.

Note: It does not appear to be possible to reset the LampCT counter to "0". If the LampTM was not reset during previous lamp changes, the reported number of hours will reflect the cumulative hours since purchase or the last reset. However, if you optical block has been replaced, it is possible that these numbers get reset to "0".


4. To display the PanelTM (total LCD panel power-on time) entry, press <1> until it displays (typically 7 presses).

The display should look as follows:
PANEL NVM OK 9 OPTION_E
7 SH SFT1 10 Diff 1
PanelTM ####

Note: This number reflects the total number of hours of usage on the TV, but it seems to be stored in the optical block, so it gets reset to "0" when the optical block is replaced. Otherwise, it cannot be changed.

5. When done, exit the service menu by turning off the TV (note: you can turn the TV back on immediately, but you should do so within about 3 seconds to avoid a lamp restart.

2005 SXRD model XBR1 (other SXRDs may vary)

1. To access the service menu, with the TV off, press the following buttons on the remote control sequentially in rapid succession (note: if the TV is already on, you can start by turning the power off, but then you should enter the full 4-button sequence within about 3 seconds to avoid a lamp restart): <DISPLAY> <5> <Volume +> <POWER>


The display will likely look as follows:
VERSION 0 0 SERVICE
VER TV
F/A : ########
CBA : ########

2. Press <JUMP> until the PANEL service menu displays (typically 3 presses).

The display will likely look as follows:
PANEL NVM OK
0 OPMODE
0 SBINT
Diff 1

3. Press <5> until the "20 Timer" category appears below PANEL (typically 5 presses). Finally, press <1> repeatedly to cycle through the menus: LMP (lamp power-on time in hours), LMPRST (lamp reset), and OPERAT (operation time). Operation time will likely be higher than the lamp time due to the fact that the fan continues to run for a time after the lamp is powered off.

The display will likely look as follows (LMP menu):
PANEL NVM OK
20 Timer
#### LMP
Diff 1

4. To reset the LMP value, select the LMPRST menu and press <3> <MUTE> <ENTER>.


5. When done, exit the service menu by turning off the TV (note: you can turn the TV back on immediately, but you should do so within about 3 seconds to avoid a lamp restart.

2002-2003 3LCD models: DX100, WE610, XBR950 (UNTESTED)

1. To access the service menu, with the TV off, press the following buttons on the remote control sequentially in rapid succession (note: if the TV is already on, you can start by turning the power off, but then you should enter the full 4-button sequence within about 3 seconds to avoid a lamp restart): <DISPLAY> <5> <Volume +> <POWER>

2. Press <5> until the OPTION-E category appears.

3. See steps 3-5 under the 2004 Grand WEGA procedure above.

2005 3LCD: A10 (UNTESTED)

1. To access the service menu, with the TV off, press the following buttons on the remote control sequentially in rapid succession (note: if the TV is already on, you can start by turning the power off, but then you should enter the full 4-button sequence within about 3 seconds to avoid a lamp restart): <DISPLAY> <5> <Volume +> <POWER>

2. Press <JUMP> until the CONFIGRATION service menu displays (typically 2 presses).

The display should look as follows:
CONFIGRATION 00 SERVICE
CP18_COLOR_SYS 00 00a0 BE Micro

3. Press <4> until the GW_SPECIAL category appears (typically 1 press).

The display should look as follows:
GW_SPECIAL 34 SERVICE
LAMP_TIME #########  BE Micro

4. To display the PANEL_TIME (total LCD panel power-on time) entry, press <4> until it displays (typically 1 more press).

The display should look as follows:
GW_SPECIAL 34 SERVICE
PANEL_TIME 02 ######## BE Micro

The panel time seems to be stored in the optical block, so it gets reset to "0" when the optical block is replaced. Otherwise, it cannot be changed.

5. To clear the LAMP_TIME entry (e.g., when changing lamps), press <5> seven times, then <1> to reach the following screen:

The display should look as follows:
OPTION_E 20 SERVICE
LAMP 01 0000 BE Micro

To reset the LampTM counter, press <3> <MUTING> <ENTER>. WRITE will be displayed in red text for awhile, followed by resetting to “0".

6. When done, exit the service menu by turning off the TV (note: you can turn the TV back on immediately, but you should do so within about 3 seconds to avoid a lamp restart.

Flashing LEDs

The "LAMP" LED should come on and stay on if your lamp is dead.

When the green "POWER" LED flashes, it indicates that the lamp is in the process of (or at least trying to) turn on.
When the red "STANDBY" LED flashes, it indicates that the TV needs service. The number of times it flashes helps diagnose the problem. It should flash rapidly between 3 and 10 times, followed by an approximately 3 second pause, followed by the series of flashes again.
