Question about Loewe Articos 55 55" Rear Projection Television

4 Answers

Color wheel I believe the color wheel finally went out. I saw your post about Loewe's instructions on disassembly and cleaning of the color wheel. Could you please send it to me. Also, when I called PanurgyOEM, I was told it's $3520 for the light engine + core charge + shipping and insurance or $1500 for the color wheel + core charge + shipping and insurance ($100). They also stated it's a special order so no returns and ETA of 4-6 weeks. This is why I'm asking about the disassembly and cleaning, because if not, I'm better off buying a new tv. Color wheel has been very noisy and I believe it may have quit, could somebody send me the cleaning instructions?

    I still need the disassembly and cleaning instructions for the color wheel, the only reason I am still asking is because I have seen where others were sent the instructions. A manual is not easy to come by and yes I already thought of that solution by myself

For disassemble you need to get service manual .

    Tools/Supplies:



    • Phillips screwdriver (magnetic tip)

    • 1/4” nut driver

    • 1/4” wrench, small adjustable wrench, or stubby Phillips (to access screw in tight spot)

    • Canned air with extender tube, a few cans

    • Optical-quality microfiber cloth

    • Clean, lint-free cloth

    • Small brush



    Precautions:



    • Do not use any cleaner that contains ammonia. A clean lint-free cloth dampened with water was adequate for me.

    • To prevent over spray, do not spray any cleaner directly on to any TV
    part. Spray on to rag only. (I only used a dampened rag to clean
    plastic and metal surfaces; no electronics or optical surfaces.)

    • Use only an optical quality microfiber cloth and/or canned air to
    clean the light engine lens, the mirror and the inside surfaces of the
    front screen.

    • Exercise caution using canned air. Do not tilt the can and allow any
    liquid propellant to escape. I had a few full cans available, and
    swapped to a new can often.

    • Keep screws removed from each panel in a different cup. Most are different sizes.

    • When disconnecting wiring connectors, note color codes for connector
    orientation when reconnecting. Most connectors only install in one
    orientation, but it’s not clearly obvious.

    • If contacting any circuit boards/wiring connectors, make sure to touch the metal frame first to discharge any static charge.



    Dis assembly Instructions:



    1. Insure TV is powered off and allowed to cool at least 2 hours (overnight if possible).



    2. Open and remove the Lamp Unit door on left side of TV. Using a
    Phillips screwdriver, loosen the 2 screws on the lamp unit and
    carefully remove the lamp unit.

    Clean lamp unit, using microfiber cloth on the lens and set aside for reinstallation.



    3. With the lamp unit removed, you can see the light engine’s color
    wheel through the small hole. I covered this hole with tape to prevent
    any dust from entering during my cleaning.



    4. Remove the lower rear cover (2 screws on each end and 9 along the back panel).



    5. Remove the cover from the Input/Output jacks by removing the 7
    silver screws securing the cover to the Input/Output modules and
    sliding the cover off the power cord grommet.



    6. Remove the front pedestal cover as follows:

    Note the blue, red and grey wire harnesses on the right
    side leading to the front panel controls, AV-3 jacks and PC slots.
    Loosen and remove these wires from their wire ties.Grasp
    the pedestal cover at the ends and gently pull outward. It is installed
    with quick-release pins and should release easily.Gently pull the pedestal cover out, being careful to guide the wiring.Carefully disconnect the 3 wiring connectors, noting the color code for reconnection.In
    preparation of removing the front screen, 2 hidden screws must be
    removed. These 2 screws secure the bottom corners of the front screen
    and are installed from the back.




    7. Remove the plastic housing where the lamp unit was removed:

    Loosen the wire tie and remove the wires from the top of the plastic housing (these wires go to the lamp door switch).Remove
    2 screws securing plastic housing. One on left side and other in base
    on right side (with limited space available, will need 1/4” wrench or
    stubby Phillips).Slowly pull housing from TV,
    until you can reach the connector to the lamp door switch. Note color
    code and disconnect wiring connector (may be easier to pull some wire
    through the hole and lift upward to remove connector).The
    front panel screw can now be seen in a recessed hole. Loosen this
    screw. (I did not remove the screw completely, to aid in
    reinstallation. Otherwise, a magnetic Phillips screwdriver may be
    needed.)8. From the area of the front panel wiring ties
    the other hidden front panel screw can be seen in a recessed hole.
    Loosen this screw.



    9. Remove 11 of the 12 screws along the back of the TV securing the front screen, leaving one loosely installed at the top.



    10. Remove 4 of the 5 screws on the front of the TV, at the bottom of the screen.



    11. While holding the screen at the top and bottom, remove the two
    remaining screws, and gently lift and pull the front screen panel away
    from the TV.

    Store the front screen assembly where the inside surfaces can be cleaned with the microfiber cloth and/or canned air.



    12. Reassemble the TV in the reverse order, remembering to remove the
    tape from the hole covering color wheel, if installed earlier in step 3.





    There are 3 fans to clean:

    The large Lamp Fan behind the lamp and light engine assemblies is clearly visible.There
    are two smaller fans mounted next to each other. One fan is mounted
    between the cable card slot and the light engine and the other fan is
    mounted just to the right directly on the light engine assembly. It’s
    somewhat inaccessible without removing the light engine, but using an
    extender tube on your canned air, it is easily cleaned.

    The lens of the light engine will have the most dust.
    Clean with canned air and the microfiber cloth. Use a corner of the
    cloth to reach beneath the plastic tabs covering the lens.



    The mirror may have a few dust particles. Gently wipe with the microfiber cloth and use canned air.

    Replacing color wheel is not a too difficult operation.

    If you do not trust yourself fixing it , you can have it done at a local repir shop for a small fee.

    Here is an example of the procedure: How To Replace the Color Wheel

    Regarding the replacement it can be ordered from partstore or Encompass Parts.

    Regarding the light engine, that is probably the most expensive part in your set, I do not think that is faulty.

How to service the colour wheel.


I'm sorry to say that the color wheel is not a field servicable part. These are usually replaced and "refurbished" at the factory. Extensive test equipment is required to properly adjust and align these modules.
