I have owned a Runco Q-750D LED projector and enjoyed it immensely for the past 2 1/2 years; The unit has performed faultlessly after thousands of hours of use but for the past couple of months i have been concerned about dust build-up on its fans as i used a flashlight to check them out and could see a small but growing amount of dust around its blades, specifically the air intake fan.
The Q-750D uses what i would describe as that standard Runco metal cover in black/silver which when screwed in place in my unit it covers the fans at a distance of about 3 inches away so that using a vacuum cleaner from the outside of the case does no good : too far a distance plus there is a metal mesh that prevents insertion of any kind of small vacuum attachment capable of reaching that deep inside the unit.
I just contacted Runco by phone inquiring about the procedure and was told that it cannot be done by the user and must be done by a Runco authorized repair station which to my ears is very/very disappointing news.
Why make it so difficult (in fact, unavailable) for owners of these Runco projectors the capability of doing something as simple, recommended and expected as vacuuming fans for dust build-up ?
Does the same apply to every Runco projector ?
My unit is sitting on a table in the middle of the room which i imagined would make vacuuming the fans a fairly easy procedure as long as i knew exactly which screws to remove from the metal cover to access the fans; I can just imagine how much more incredibly difficult it would be having to remove such huge and heavy projectors from a ceiling mount or custom wall mount, package the unit, hopefully find a local Runco repair station to do the "job" at a reasonable time, all that at a cost i imagine would be hundreds of dollars !
The Runco rep was very surprised with my question and told me that he had never had similar inquiry; He pointed out several times that the Runco uses a sealed DLP light engine, which i was fully aware, and therefore does not need any vacuuming !
I reminded him in turn of the danger of dust build-up blocking air intake or exhaust fan blades which would slowly but surely start to increase internal temperature that could at some point lead to failure for same parts more prone to heat degradation, and he again seemed very surprised by my statement.
Does anyone here have any suggestions for this conundrum ? Any other Runco owners that feel likewise, concerned about dust build-up on fan blades with the only option given is having it done at a repair facility ?
Any help would be much appreciated...
