ËImproving the Z9000U units
(Program version-up for HTPC (Home Theater PC) compatibility, performance upgrading and lip
synchronization improvement)
The Z9000U units have been improved in the following 3 points. These improvements can be
confirmed by looking at the program versions.
Redesigned circuitry
Program version and PC interface version
z Z901819 and Z901905
(CPCI0051CE01)
x Z901927
(CPCI0051CE05)
c Z901Z25 - Z902220
(CPCI0051CE05)
To implement the above improvements from Level-z to Level-c, it is necessary to update the PC
interface board programs, modify the hardware, and change some parameter settings. There is no
need to replace the PC interface board itself. If this board is replaced, however, the background
setting must be additionally readjusted.
To get the Level-z unit compatible with HTPC, just update the programs. To upgrade the Levelxunit to Level-c, update the programs and make some readjustments. All these are discussed
below.

Upgrading from Level-z to Level-c
1) Checking the unit
» Select "ST ATUS" on the menu screen and look at the right bottom of the screen to check the program
version. If the version is "Z901819" or "Z901905", take the following procedures.
2) Jotting down the process parameters.
» Note down the existing settings specified below because there may be a problem during the
reprogramming. Your notepad can be used to confirm the settings after the reprogramming.
(1) Power on the unit and call the process mode.
To do so, use the keys on the remote controller or on the unit. Press the keys "INPUT → UP →
DOWN → ENTER → ENTER → MENU" in this order . Or just press the S001 s witch on the main
PWB.
Select "A/D , DLP and DTV" in this order on the process menu. Write down the follo wing parameters.
(2)
A/D : A/D converter input setting
DLP : Background setting
DTV : Component mode A/D setting
(3) Exit from the process menu. Press the keys in the same order as for entering this mode.

3) Modifying the hardware
» Remove the PC interface board from the unit. Make the following modifications.
(1) Add two jumper leads.
Connect one jumper between TL88 and TL136 and the other between TL87 and TL140. Apply
adhesive to the specified points to secure the jumpers. Refer to the attachment file “0051 Modifications”.
(2) Change the resistor constants.
Change the constants of the following jumper resistors on the board.
R82: Not mounted → 0 ohm
R69, R93 and R94: 0 ohm → abolished
R76: Not mounted → 47 ohms
For more details, refer to the attachment file 0051 Modifications.
4) Updating the programs
» Get the following two programs updated.
XV-Z9000U/E
SUPPLEMENT
Main program Z9000_020220.bhx
CVIC program cvic_AB_Z9000_1219al.bhx
The reprogramming procedures are the same as for the projector data progr am. Ref er to the attach
ment file "Z9000Manual.doc".
5) Checking and readjusting the process data
» Enter the process mode again and check the parameters jotted down in Step 2 above.
A/D : A/D converter input setting
DLP : Background setting
DTV : Component mode A/D setting
If any of them has been accidentally deleted, reenter the same value.
» Enter the process menu "SSS" and click on "S2".
» For readjusting the video line, refer to the Service Manual.
Feed the NTSC video signal to the "INPUT4" pin. Make sure the signal has clear white level
(100% white) and black level (0% black) (setup at 0%). Select "VIDEO1" on the process menu.
Adjust the "BRIGHT" setting until a bit dropout occurs at the black side. Then adjust the "CONTRAST" setting until a bit dropout occurs at the white side.
» Enter the process menu "SSS", click on "S4" and exit from this process.
