    My Z2 is only a Month old but I had a green dust blob within a couple of days of use...then last night when we all sat down to watch The Incredibles I saw an even brighter blue blob straight in the middle of the screen!

    Now I have read a few older threads on here about dust blobs on the Z2 and have also looked at the cleaning thread over on AVS but I am still reluctant to take my Z2 apart to clean it. I suppose that is the only thing I can do but wondered if anyone had come up with any ways to try and cut down on the amount of dust blobs they get?

    There was mention in one of the older threads about Sanyo issuing a rubber gromet of some kind for around the lens shift area as an upgrade? Anyone know if this was indeed the case?

    I dont know what I would get if I contacted the retailer I bought the projector from either as it was from Pixmania over the web and they are based in France :(

    Another dust blob appeared yesterday :(

    Looks like I am going to have to take my Z2 apart.

    I've got a bl**dy annoying dust blob on my Z2 that simply refuses to budge! It appears as a green blob on dark/black scenes, so it stands out like a sore thumb :mad:

    Anybody got any nifty tips for shifting these little blighters? I have taken my projector apart and tried compressed air five times so far and it's still there. :(

    cheers

    I dont suppose you have any pictures of where exactly you shifted the dust blob from ?

    I still havn't had the lid off my Z2 and am always a little wary of these things in case I end up making it worse !!! After looking at the thread on AVS I am pretty sure I know where to blast with air but it would be great if you could point out where you found the blob on yours.

    Cleric,

    Try this - http://www.avsforum.com/avs-vb/show...ht=Z2+Dust+Blob

    All the pictures you will need. Generally the colour of the dust spot will be the panel that has the dust on it so gives you an idea where it is.

    It is quite easy to do as long as you are careful (especially removing the outer case as there are some wires attached) had a few dust spots in the early days, not had any for some time now. All changed when the unit was wall mounted.

    you shouldn't have any problems if you are following the guide, but as Gavin say's [B]do ensure[/B] that the can is held vertically, otherwise you will be spraying liquid onto the LCD panels which I would imagine will have some horrific results.

    I had someone hold the Z2 on a tilt to make sure that can was always up-right. You will not need to blast the air for more than a few seconds and a couple of blasts should do the trick.

    Oh....and good luck!

    No and it's getting more annoying by the minute! :mad:

    I'm going to give the "shove a thin piece of paper down between the panels" technique a go and will see if that shifts it.

    cheers

    :eek: Can you damage the panels by doing this?

    Why not take it to a service engineer and have them deal with it, it will be under warrenty still will it not?

    Isn't there special air cans that wont spray proellant?

    I've used the air duster on other things and I don't think I'd trust myself when it comes to the Pj as there's always some prop. coming out :suicide:

    I have literally just finished putting my Z2 back on its ceiling mount after cleaning it. No idea if it has worked as the room is too bright to try at the moment but I will test it later and hopefully the blobs will be all gone ;)

    Well, tried it...and all the dust blobs that were on my Z2 are now gone :thumbsup:


    ...but a different one has appeared :thumbsdow

    It is in a different place and is a lot lighter green than the others but it looks like I will be giving the pj another clean this week. :(

    Was it just the spray you used Cleric?

    Any propellant leak?

    I have taken a photo of my Sanyo Z2, which the cover off, ready to start another round of air spraying!! As I know the dust blob is on the green panel, does anybody know which panel is which, can you label A, B & C for me??

    Thanks

    I can answer my own question!! :clap:

    Looking down onto those orange cables, at the back of each one is a coloured dot, one Red, one Blue and one Green, I would assume that ties in with the colour of the LCD.

    So, A = Blue, B= Red and C=Green.

    cheers

    Gavin

    ##STOP PRESS## Update: I've got the little f:censored: Just tested out a blank screen and no green blob :clap: I also found a tiny spider in there as well :eek: If it can get in, then dust definately can!

    Yes just used a can of spray air from Maplins.

    I had a few tests with it first to get used to making sure there was no liquid. I held the can vertical all the time and moved the Z2 around it so as to get everywhere.

    Thanks Cleric - whether vertical or not, mine always seems to squirt at the beginning or end :rolleyes: so a new can may be in order!
