LAMP DOES NOT LIGHT UP

Plug in the AC Cord.

Note:

When doing troubleshooting over again, be sure to
turn the power off and unplug the AC Cord.

Is there a click sound to turn the
Relay ON?
(Relay: RL803 on the Power C.B.A.
(Circuit Board P))

YES

Does the Power LED (D6701) on the
Operation C.B.A. light up red?

Before doing this troubleshooting, confirm that all connector cables in the unit are connected to the connectors correctly.
In particular, confirm the following connector cables:

• LVDS Cable (20-pin Cable):

Between PL1 on the DMD Drive C.B.A. (Circuit Board L) and PDG4 on the Main C.B.A. (Circuit Board DG)

• Thermostat/Cover Switch Connector Cable: Between Thermostat/Cover Switch and PA5 on the Base C.B.A. (Circuit Board A)
• B2 Connector Cable:

Between B2 on the Ballast C.B.A. and PA6 on the Base C.B.A. (Circuit Board A)

• Color Wheel F.P.C.:

PL3 on the DMD Drive C.B.A. (Circuit Board L)

• Lamp Connector Cable:

Lamp socket

Note:
If a cable is disconnected, the Power LED flashes or the Unit shuts off.

YES

Does the Power LED (D6701) on the
Operation C.B.A. flash green?

Error 1) ~ 9) occurs.
(Refer to "LED INDICATION FOR
ERROR CONDITION")

Refer to "How to solve the problem
indicated by the Error Indication of
LED."
and perform troubleshooting.

Replace the TV Unit (Power C.B.A. (Circuit Board P)).

Turn the power ON.
