I had the same problem and the stupid tv would shut off after 1 minute. We opened the silver front panel , took the bulb out cleaned it, took the cover off the grey box to the right and very carefully vaccumed the filter and wiped it off with a microfiber cloth. It works great now!!! Make sure you unplug your tv before messing with it.

    I just had the same message come up. If you are a handy person you should be able to do this yourself. It does require the removal of a few dozen screws so take your time and be careful. The filter on this model is located in the back of the TV, dead center. You have to move the silver box with all the wires coming out of it, you should be able to move it out of the way without removing any of the wires. The filter housing is directly behind in the very middle of the TV. It has 2 larger screws on the top and 2 smaller screws on each side of it. Once these have been removed it should pull right off exposing the filter. The filter is held on by 4 of its own screws. Carefully remove the filter and wash it, once dry replace and reassemble. FYI on this model there is no filter located anywhere near the bulb.

An OSD advising "AIR FILTER CLEANING" is displayed


You must remove the light engine then locate the filter by removing a black cowel looking device at top of engine held by 4 screws,then you will see the rectagular filter held with 4 screws you must pry out the filter it does not come out easy. Clean it with clear water and blow out with compressed air look at it through light to make sure it is clean. reassemble The sevice manual will show you how to remove the light engine.
