    Hi
    any tips for cleaning the filter??? also after pouring over instructions it mentions wiping the dust detection window loacated behind the filter....i have never done this as i did'nt know about it what does it do? if not cleaned what happens? is this why i have increased fan speed?

    also i know there is an internal warning system to alert fan cleaning but really how often should you clean it??

    thx

    The manufacturer's advice is to clean the filter every 100 hours. Either let the 100 hours come up and the PJ will warn you with an on-screen messange and some red flashing lights on the PJ itself, or simply reset it at 99 hrs to save the fuss.

    I use a vacuum cleaner to clean the filter. First I tried the brush adapter but it didn't seem to do much. So instead I use the pipe without any tools and suck the dust out the opposite way to how the fan sucks the air in (I figure if dust is trapped by the filter I don't wanna force it through).

    Be careful though, depending on how powerful the vacuum cleaner is, you may suck the foam off the frame. We have a Dyson which has a button on the pipe which I think is designed to reduce the suction (for curtains and the like) - this is useful for cleaning filters.

    The dust detection window is on the outer plastic cover that you take off to allow you to get at and remove the filter. It's a small clear piece of plastic on the side (left, but my PJ is ceiling mounted). I also vacuum this outer cover, must admit I've never seen any dust on this. Even the filter only has a slight layer of dust after 100 hrs..PJ

    Thanks for advice think i am at the end of staying with this projector!!!!!!!!!!....watched another film last night and after 30 mins fan speed picked up with a whine , simply got up and turned the whole thing off and went to bed......this is probably the biggest waste of money i have spent and so annoying when the Pic's are so good........even have no heating on in winter still no help have tried every position , still the same pick up on fan noise....the most annoying thing is my old Panny 100 used to heat up with the fan picking up speed to cool the internals down but the returned back to whisper......on the Hitachi once it heats up the fan goes and thats it!!!!!

    AHHHHHHHHHHH :thumbsdow :mad: :(

    Simply can't rant enough about this projector

    A few TX's have loud fans, they catch on something in the innards. Your issue may be something different however. Either way, If it's in warranty then get it seen to. I never notice the fan noise on my TX, can't say if/when it speeds up or slows down. And I don't have the sound loud usually, in case I wake up the kids. I think this is the norm, it's a quiet projector usually...PJ

    I take the opportunity to inquire if there are any new ideas to cleaning dust blobs in the TX100.
    I did (several times) the compressed air routine, but on the left side of the image (pj is ceiling mounted) there is a concentration of dust that just doesn't move.

    I do wonder whether taking out the lamp would allow better access for blowing compressed air?...PJ
