elsiegee40 Posted February 3, 2011 Posted February 3, 2011 We've got a 6 month old Casio projector that's projecting a violet image (occasionally dark purple) with black flecks. the lens has been cleaned... it's as if there's dust behind the lens. Has anyone experienced this?
plexer Posted February 3, 2011 Posted February 3, 2011 Not seen that before but it could be a fault with the colour wheel, get it logged with Casio I guess. Ben
BatchFile Posted February 3, 2011 Posted February 3, 2011 Not seen it either, but ... isn't that one of the lampless ones? I take it you've checked the cable? (worth a look if not) Otherwise, it sounds like a problem with either the internal processing gatgetrymabob, or one of the light sources going on the blink, in either case a warranty claim
elsiegee40 Posted February 3, 2011 Author Posted February 3, 2011 Got a call into support already - waiting for response. I was just wondering if anyone else had had this.
Marc-Engineer Posted February 4, 2011 Posted February 4, 2011 Yes i have had some in they get clogged with dust on the optical engine, can not be cleaned buy a user it must go to service if it is dust for a deep clean, just to check it can you winfd the lens fully out and in see if you can focus the purple spots they will be at a different point to normal focus if it is dust, you might not get it quite in focus but you will see it start to come in. Try it and let me know. PS if it is dust it is NOT covered to clean this under warrenty. Marc Projector Engineer
plexer Posted February 4, 2011 Posted February 4, 2011 Come on it's only 6 months old if it's been used in the environment it was designed for i.e a normal one how can they not sort it under warranty? Ben 1
Marc-Engineer Posted February 4, 2011 Posted February 4, 2011 HI, its because a deep clean is classed as maintainence not a breakdown. Marc Projector Engineer
localzuk Posted February 4, 2011 Posted February 4, 2011 HI, its because a deep clean is classed as maintainence not a breakdown. Marc Projector Engineer Problem is, Casio sell them to educational establishments with 5 year warranties. It is normal in an educational establishment for dust to exist. So, how is it not a breakdown that the device cannot handle dust after 6 months in the environment it is designed for?
elsiegee40 Posted February 4, 2011 Author Posted February 4, 2011 Given that it's flashing purple, the problem is slightly more than dust flecks behind the lense. I too agree that a filter-free product should last more than 6 months before needing a deep clean and would be prepared to challenge them on that. Sales of goods act - fit for purpose. I've just heard of another school locally that's had a similar and am awaiting a response from their NM to find out whether he got it dealt with under guarantee.
Marc-Engineer Posted February 4, 2011 Posted February 4, 2011 Hi i think we ned clarification i was not told it was "flashing purple" i was told it was purple flecks whis is consistant with requiring deep clean, if it is a pixel or flashing problem then i agree it is a warrenty issue. I do see quite a few projectors that have dust ingress after only 6 months to a year, i am not defending the "its not warrenty" issue i would love it to be covred fior deep cleans in its first year or however long. With more info or a phone number i would be happy to offer FREE help and advice to sort this. I am basing my assuption for deep clean on my experiance and knowlage and the brief description of the problem above. Oh and the dust is not generally behind the lens they are normally in the optical engine. Marc Projector Engineer
localzuk Posted February 4, 2011 Posted February 4, 2011 The OP said 'purple image with black flecks'
hullpete Posted February 4, 2011 Posted February 4, 2011 knew this would happen, (my previous reply to another thread) how can a filterless projector last the distance, in my opinion we will only see this problem escalate, casio may be busy this year with swap outs and warranty calls,

Has anyone experienced this? Problem as stated in the original post I've just had word back form the other school. Their projector was sent back to Casio and had the optics replaced under guarantee. Ours will be doing the same next week hopefully.

DLP technology (ie. filterless) has been around for a long, long time, and is a proven technology. The only new thing with the casio's is the type of optics, and as with any first generation technology there will no doubt be a few problems.
glennda Posted February 4, 2011 Posted February 4, 2011 There is bound to be problems - there always is when new things are released - we have about 5 of these and hopefully with the works we are getting done will have more put in. They are my projector of choice for now - although I do like the look of the ViewSonic Interactive projectors but would need to see it in a school environment rather then just at Bett.
elsiegee40 Posted February 4, 2011 Author Posted February 4, 2011 Unless I have serious problems getting this fixed under warranty, I'm still intending to go ahead with replacing all our projectors with the Casios. I'm hoping we've just been unlucky... it's not like dozens of people have been on edugeek moaning about them.
hullpete Posted February 4, 2011 Posted February 4, 2011 just stating an opinion, hopefully they will sort the problems out, but for now the sheer amount of heat they excreet and the filterless technology do not bode well in my estimations, but again thats just my view,
tech_guy Posted February 4, 2011 Posted February 4, 2011 I had a similar problem with a projector in a church hall. Bizarre colours appearing but not all the time. We had to get a scaffolding tower to get up there and have a look and when we got up there we found a squirrel or a rat had come out of the roof space down the pole and taken some bites out of the vga cable!
RTFM Posted February 5, 2011 Posted February 5, 2011 We've got nearly 20 of these now and had some for nearing a year and not had a single issue with any of them :\ fingers crossed it stays that way!

The heat and filterless aspect has been around for a long time, so I can't see it being a problem.
Marc-Engineer Posted February 7, 2011 Posted February 7, 2011 Firstly i am pleased it turned out ok in the end as regurds getting it sorted, as for DLP i would think around 1 in 50 projectors are DLP and i do see a lot or the first generation DLP faulty the newer ones not so many (yet) i still think LCD are a better technology reguarding reliability (less wear from moving parts) and definatly better colour rendition on LCD (up to now). But i think new thech is a good thing and this is very new tech not lampless as claimed but a new style of combination lamp with a longer life, my only problem (that i can think of) is the half life of the two different types of lamp in the Casio unit, they will age at different rates giving a different colour temp range with age. But hey this is all new, all we can do is wait and see, as they say only time will tell. Marc Projector Engineer
psydii Posted February 11, 2011 Posted February 11, 2011 I've been hearing dark muttering coming out of 'Channel Partners' about these projectors. Hard to tell if it's just that these things are going to completely shake up the market and the resellers are scared of loosing their cash cow (bulb sales) or whether there are real insidious technical issues. That said, I did once have a large batch of projectors that we really poor performers. They were branded OEM jobs. Very quickly the Chinese manufacturer stepped up to the plate to ensure we received a good service for the three years of the warranty - even shipping us spare stock and a shipping crate with preprinted labels to ensure minimum disruption possible given the failure rate (sometime 1 a month). So even if they turn out to be dogs, as long as the manufacturer honors the warranty there shouldn't be much impact to the end user. It'll be interesting to hear how they handle the dust issue.
elsiegee40 Posted February 11, 2011 Author Posted February 11, 2011 When I rang they were very pleasant and agreed to take it straight in to look at it. It's a joy to speak to a UK based support desk!
Marc-Engineer Posted February 15, 2011 Posted February 15, 2011 I must dissagree strongly i find DLP NOT to be a proven tech, i see more DLP faulty than is normal for the amount that is out there, i often see broken colour wheels, it is (in my opinion) a poor tech, i see far les (by percentege) LCD machines. There are too many moving parts and timing issues with DLP they can not possibley last as long as LCD. and they are not as efficiant with power consuption or light output as LCD (EG. Epson X9). And by comparasen have poor colour rendition. Marc Projector Engineer
