MITSUBISHI LASERVUE - HOW TO REMOVE LIGHT SOURCE ASSEMBLY & INSTALLATION

LIGHT SOURCE ASSEMBLY REMOVAL

1. Prior to removing the Light Source Assembly, AC power must be removed. AC power must not be re-applied until all covers are replaced back into their original position, all screws are in place.
2. The Fiber Optic Cable is sensitive to excessive pulling, bending and crushing forces. Do not bend cable more sharply than a bend radius of 100mm (4 inches). Do not pull on the cable. Do not crush the cable or allow it to kink. Do not allow the end of the fiber optic cable to make contact with any surface including fingers.

• Remove the Electrical Chassis. [Described one among the previous posts here]]
• Loosen the Tape used to secure the Fiber Optic Cable to the back wall.
• Disconnect all electrical connectors from the bottom of the Light Source Assembly.
• Remove 6 screws (a).
• Note: the Hinges at the lower left and right side will now hold The Light Source Assembly.

• Holding the Light Source Assembly with both hands at the bottom, pull the entire Light Source straight back slightly within the Hinge slots.
• Carefully tilt back the Light Source Assembly from the top and secure in place using the support arms.

• Disconnect the four 8mm Fiber Optic Cable Connectors from the Light Source Assembly. Caution: Never loosen or tighten the chuck nuts used to attach the cable to the connectors.
• After disconnecting the Fiber Optic Cable, temporarily secure it to the back wall to prevent damage.
• Use the End Caps and Special Yellow Tape supplied with the replacement Light Source or Optical Engine to cover and protect the ends of the Fiber Optic Cables and Laser Modules until reassembly.

• To remove the Light Source Assembly, tilt it back up and store the support arms. Then while supporting the assembly, remove the eight screws (a) and lift the assembly out.

Light Source Assembly Installation

• To install the Light Source Assembly, reverse the removal procedure.
• Use an 8mm open end torque wrench to tighten the Fiber Optic Cable Connectors to 0.2N • m (+/- 3%).  NOTE: When a Light Source Assembly or Light Engine is ordered, an 8mm open end torque wrench will be supplied on loan from the Parts Department.
• Prior to applying AC power re-assemble the set.

If the Light Source Assembly has been replaced, perform the following data transfer procedures: Reset SENSOR-RGB Data.

1. Plug in the TV and allow it to boot-up, but do not turn it On (Standby condition).
2. On the front panel, press and hold the <MENU> and <CHANNEL S> buttons at the same time about 5 seconds until the STATUS LED lights green for 3 seconds.

• Memorize SENSOR-RGB

1. Turn the TV on and allow it to warm up for 5 minutes.
2. Press the <MENU> button on the remote control. The Customer Menu will appear.
3. Press the <2-4-5-7> buttons. The Service Menu will appear.
4. Press the <0> button. The Data Selection Menu will appear.
5. Use the <TS> buttons to select “MEMORIZE SENSOR-RGB” and press <ENTER>. A green square will appear in the on screen display indicating the memorization process was successful. If a red square appears, repeat the Reset SENSOR-RGB Data and Memorize SENSOR-RGB Data procedures.

FORD MONDEO - HOW TO CHECK ANTI-THEFT ALARM SYSTEM

ANTI-THEFT ALARM SYSTEM

• The system includes a start inhibitor circuit, which makes it impossible to start the engine with the system armed.
• The movement sensors consist of two ultrasonic units, located in the “B” pillars, incorporating transmitters and receivers (see illustrations). The receivers check that the echo frequency matches the original frequency. If there is any significant difference, the system triggers the alarm.

• The system module is located on a bracket beneath the right-hand side of the fascia. The set and reset switches are located in a housing by the lock barrel holder in the doors, tailgate or boot lid.
• To allow temporary opening of the tailgate or boot lid, an inhibit switch is fitted to the lock barrel. This suppresses the alarm system until the tailgate or boot lid is closed again.
• Where remote central locking is fitted, an infra-red receiver is located on the exterior door handle (see illustration). Note that excessive heat can destroy this receiver; therefore, it should be covered with aluminum tape if (for instance) a paint-drying heat process is to be used.
• The alarm system is fitted with its own horn. On Hatchback and Saloon models, it is located on the left-hand side of the luggage compartment; on Estate models, it is located on the right-hand side of the luggage compartment (see illustration).
• The alarm system incorporates a self-test function, which can be activated by operating the bonnet switch or one of the lock position switches eight times within 10 seconds. During the check, the horn or buzzer issues acoustic signals, which should occur every time a door, bonnet or tailgate is opened. If the doors are double-locked, the signal will occur when something is moved within the passenger compartment. A more comprehensive test can be made using the Ford FDS 2000 diagnostic tester.
• The door lock switches associated with the alarm system are located behind the door trim panels (see illustration).

There are two front panel LEDs, “Power” and “Status.” The LED display shows the current status or indicates a possible malfunction.  If an abnormal condition is indicated, proceed to the Error Code Operational Check for more specific information.

Power LED [Normal Condition]	Status LED	Condition
Off	Off	Off (Standby)
Fast Blinking Green	Off	Initialization (40 - 60 seconds after set plugged in or System Reset)
Green	Off	Power On
Slow Blinking Green	Off	Power On Timer is set
Abnormal Indications
Off	Yellow	* Temperature high – room hot. * Laser unit temperature is abnormally high. * Optical fiber temperature is abnormally high
Off	Blinking Yellow	Cover-back (top/bottom)is open.  Yellow Laser unit is not assembled completely.
Off	Red	* Laser unit failure * Laser abnormal brightness * Linear motor failure * Communication in laser unit failure Chassis side failure *Communication with laser micro fail * Communication with engine fail * No Lamp-EN, No ASIC-ready * DVI cable disconnection Circuit failure (short)
Off	Blinking Red	Fan Stop (DMD Fan, Fan in laser unit)

ERROR CODE OPERATIONAL CHECK

When the Status LED indicates an abnormal condition, perform the Error Code Operational Check.

To activate, press the front panel INPUT and MENU buttons at the same time and hold for 5 seconds.
