CP2000-ZX LVPS Upgrade
Instruction Sheet
INTRODUCTION
Use the following instructions when upgrading the Low Voltage Power Supply (Tectrol to Astec
model) in CP2000-ZX (116-001101-xx, 116-001113-xx, 116-001124-xx) projectors.
The entire procedure takes approximately 45 minutes to complete.
KIT REQUIRED
003-003075-01 CP2000-ZX LVPS Upgrade Kit (includes low voltage power supply complete with AC and DC
harnessing in place, 1/8”plastic slot driver, instructions)
TOOLS REQUIRED
CP2000-ZX:
• Phillips #3, #2 (long stem)
• Wrench (to loosen ground nut)
• 1/8” plastic slot driver (for LVPS POT adjustments in CP2000-ZX projectors)
SAFETY AND WARNING GUIDELINES
HIGH VOLTAGES MAY BE EXPOSED: Always power down and disconnect power
sources prior to servicing. Once the projector is powered down, allow the cooling fans to
automatically turn OFF before disconnecting from AC and opening the projector. Depending on
your projector model this can take 10-15 minutes.
QUALIFIED SERVICE TECHNICIANS REQUIRED: All module replacement
procedures must be performed by qualified service technicians.
NON-INSULATED DANGEROUS VOLTAGES MAY BE EXPOSED: Always
disconnect from AC prior to disassembly.
OBSERVE ALL ELECTROSTATIC PRECAUTIONS: Use a grounded wrist strap
when handling electronic assemblies.
Never operate the projector (or the fans) without all the covers installed.

5. Remove the EMI shield. (Figure 3)
a. Loosen the 2 screws securing the shield to the
frame. Slide the shield off to gain access to LVPS
harness connections.
6. Disconnect the DC harnesses (P1 & P2) from the
Motherboard. TIP: For easier access to the DC harness
connections, you may find it necessary to remove the black
GPIO connector (J28) next to it first. (Figure 4)
7. Remove the white plastic cover over the AC Relay,
and disconnect the blue (top) and black (bottom)
signal harnesses. (Figure 5)
8. Also from the AC Relay, disconnect the blue (2nd
from the top) and brown (bottom) harnesses on the
other side. Keep the white harnesses underneath
intact. (Figure 5)

9. Remove the nut securing the main ground to the firewall.
10. Remove the 4, M6 screws securing the LVPS assembly. NOTE: In -03 models remove the LED as
well. Keep it for use with the new LVPS assembly. (Figure 6)
11. Secure the new LVPS using the same mounting holes and hardware used with the old assembly.
Orient the LVPS with the high-pot adjustments on the right-hand side.
12. Install the LED to the bottom left screw used to secure the LVPS to the firewall. (Figure 7)
13. Secure green harness (ground) to the main earth ground stud using the nut removed in STEP 9.

14. Re-connect the four signal harnesses to the AC relay.
TIP: Screws only need to be loosened to slip harnesses
on. Refer back to Figure 5 for the location of signal
harness connections. IMPORTANT! Loop the blue
and black signal harnesses around the clip once
(Figure 8) before connecting.
15. Re-connect the DC harnesses from the LVPS to the
Motherboard (PI & P2).
16. Re-connect J28 (black GPIO connector) to the Motherboard, if removed in STEP 6.
17. Replace the plastic AC relay cover.
18. Replace the EMI shield.
19. Replace the LVPS/Ballast cover.
20. Replace the top font cover.
To adjust LVPS voltage rails:
Use the non-conductive plastic slot driver
provided in the service kit when adjusting the LVPS voltage
rails on the CP2000-ZX LVPS.
LVPS rail adjustment must be performed
by a qualified service technician.
1. Remove the LVPS/ballast side cover.
2. Adjust POT’s to 3.366 +/-0.003v and 5.110v +/-0.003v.
Observe the CDP to see the adjustment value of the rails.
