    I have an Epson TW100 projector that has a large dust fiber on my blue LCD panel. When I get dark areas on my screen it shows up as a 3inch hazy blue dot (reminds me of the Kenndy trial in Florida) I defocus and I can see the fiber in blue.

    Has anyone cleaned the LCD panels on this projector, or one simalar to it? I have to open the case to get to them and I'd like to know as much as possible before I dive in there.

    Greetings

    Try opening up the bulb chamber and take the bulb out ... then use a can of compressed air to blow in the chamber ...

    It may help ...

    regards

    I tried that, and I also tried getting in through the filter door, neither worked. It looks like I need to open the case to get to it?

    Is anyone familiar with this projector?

    I am not familiar with the internal layout of that particular projector. On my previous projector (a Sharpvision XVZ1U), I had to remove a cover then remove the cooling fan and bulb to get access to the panel. In my current unit (a Sony 11HT), I have to remove a cover and pull up the bulb assembly. Try shining a bright lamp/flashlight in the area. Can you see the dust?

    I just tried that -- no luck! I see what looks like a single panel or polarizer, but not much detail. The coatings on the lens prevent me from getting a close look.

    Do some projectors have "sealed light paths" that prevent access to the LCD's? Or is this just refering to the lens assembly?

    I've called several service centere and they all say "we aren't familiar with that projector but we can clean it, bring it in," and Epson says "don't touch it, it's a 'sealed light path' and requires a specialist!" I figure that if a service center can do it $100 - $300, I can do it myself.

    It's very hard to get any specific information!

    Does anyone have any idea where I can go for help with this? A friendly service center, projector guru website, anywhere?

    Hi David,

    I'm a new owner of a TW100 - but haven't familiarised myself enough with it just yet.

    Perhaps anyone with experience with the Yamaha LPX-500 may be able to help you out? It is essentially a re-badged TW100.

    Failing that ... you're best bet may just be to swallow that chunk of change and let Epson take care of it ...

    Try AVSforum. I had a similar situation on my Sanyo Z1, a great big dust blob that multiplied when I tried blowing compressed air from the outside. I had to open the case and actually locate where the LCD panels are. A prolonged burst of compressed air cleared it all. While I had a website showing the details on how to go about it, I would suggest u look at it as well to give u a good idea as to what is involved. Here is the link. http://www.hubc.org.sg/MyWeb/Z1_dustblob_removal.asp

    I'm sure it can help just take ur time.

    I experienced a hair showing up on the green LCD panel of my Panasonic PT-L300 with 30 hours on the projector. After obtaining a service manual, which did not give much help regarding cleaning, I went ahead and took off the top cover. I used a pipe cleaner and compressed air to gently clean the dust off all three LCD panels. It worked and the green spot is now gone.
