I've yet to see a single LCD or normal DLP projector with instant on/off. Can you give some examples?

Yes the Epsons dont have a cool off time either they have a different lamp technology they are instant off too.
Yes the "normal" BenQ, Epson, Sanyo do have extended cool off times but NOT Epson.
As you say it is good not to have to wait for cool off times.

hi MarcQuote:
any projector 1000 hrs and most need a deep clean
What do you call a "deep clean" :)

We've got a couple of Epsons that have no/very short cool off time. They still take a while to turn on though and give a really poor image with some text unreadable.
You still have to factor in things like the cost of replacement lamps for traditional projectors and the fact that they use more power than the Casios.
Thanks for all the input.
I printed off this thread for My ICT Co-ord and he's decided to go with the Casio's.

(Mind you - I'm imagining 3 years from now when all the Casio outputs look horrible - I'll bet there will be lots of posts from people saying they knew they wouldn't last :) )
All of the recent Epsons THE X range onwards have instant turn off well less that 2 seconds.
Any Epson projector of this type taking longer to turn off has a fault and should be reported as all education Epsons have 3 years ON SITE warrenty.
Also the lamps are cheaper at around £135 and with claimed 5000 life.
A deep clean is where we strip trhe projector to the case clean the optical engine, Mirrors, diffusers, prism, and depending on its make the image device (usually LCD) these are cleaned in a dust free room and then reassembled and tested with out put mesured and compared to when it came in we then write an engineers report on what we found this goes to the customer with the Projector.

How much to you charge for that sort of work (if you don't mind me asking)Quote:

And surely, projector manufacturers don't specify that level of cleaning?
(or do they????)
Or do you just offer a sort of gold plated projector service contract :)

Vacuum cleaner - what's a vacuum cleaner? :)
Hi Simon
The cost for this clean is £70 ans yes munufacturers DO recomend this clean, i trained with several of the manufacturers to do this for them.
It can prolong the life of your projectors by 50% or more.
It also makes them more uasable during their life keeping them at optimum brightness.

These cleans are like a service for your car.
We recommend that anyone using a large number of projectors should consider a maintenance contract to keep al of their equipment in good repair.
It also helps with the fact that you know exactly what kit you have and what condition it is in, so you dont get nasty surprises of kit failing unexpectedly.
I would say however that these cleans do not guarantee that your projectors will last longer or perform better. It is a procedure recommended by manufacturers but it will not make a five year old projector on its last legs like new again!
We installed one of the Casio LED projectors in March this year, we had to send it back in the summer with an overheating fault...That's been the only glitch, otherwise the image is great, functionality is good and it's very easy to set up and configure. They turned the repair around in about 15 days.
ben604:
15 days!!! thats terrible! did they supply you with a swap out unit?
Our staff wouldn't wear 1 day let alone 15 days without their IWB!
15 days isn't a bad turn around without any form of dedicated warranty/contract. Our old LFT laptops would take around that to get back from repair, our Fujitsu-Siemens laptops took even longer.
Can't compare on the projector front though - never had a projector die in warranty!
It was in the holidays so I wasn't harassing them, I'm sure they'd turn them around quicker under duress...
Just as a comaparison (Oh and i dont work for Epson) our Epson education warrenty is repair or replace in 24 hrs from stock.
