Yes they can and do expect that. What would the customer even do? Pop out the diode array, test and desolder the faulty diodes and then replace them with some 445nm diodes they bought from a laser forum? Yeah right! It's not a lamp or even a lamp ballast. "Oh look, the top-row, 4th down diode isn't working when I shine its blinding light on the wall!" As a company you wouldn't even want regular people to be servicing that component of the device. The diodes are already designed to last a lot longer than those lamp-based projectors, so the customer has already purchased the projector for its longevity.

I'm actually surprised that the laser projector manufacturer made that diode array accessible at all. I would've never added a door to the outside of the projector, which would only encourage easy access to the diode array. It's practically negligent that the manufacturer designed the projector such that the laser array can be powered up while being unseated from the projector unit at all!

C doesn't have repair centers for these units? That doesn't seem very profitable for them. Dell charges more for labor than the parts they put in.
So, if a unit becomes off color due to a few diodes failing they expect the customer to chuck it in the garbage and buy a new unit?

Keep posting ideas for them to read and use. That always helps a lot. I would be surprised if they didn't have ppl reading areas like this for information.

Apple ? I don't care for Apple and never owned any of their products AFAIK. Icrap pretty well describes their stuff from what I read.

Remember that we're talking about a laser-based projector here, not a traditional mercury-lamp projector. Replacing the diode array is not like replacing a lamp; it's more akin to replacing the ballast in a regular projector, which is usually not made to be user serviceable, and lasts far longer than the lamp. When the ballast goes, quite often the suggestion is to just get a new projector. It's sad but true. By the time the ballast goes out, the projector is so old and out of warranty that it isn't worth the cost to have it serviced, if you can find the parts.

The same kind of thing with these laser-based projectors, only these are not made to work with replaceable lamps. The diode array is the "lamp," and designed for longevity; it's why people buy these projectors in the first place. Sure, if they burn out within the first 3 years/6000hrs you can send them back for repair or replacement, but they're supposed to last to about 20,000 hours. It may even be the fluorescent wheel that gives up the ghost before the diodes. Compare that to what you'd spend replacing your $300 low-lumen lamp every 2000 hours with a regular projector and you're already looking at a cost savings on the lifetime of your $800 projector--even if it dies right after its 6000 hour warranty is up. Hell, by the time you'd reasonably get around to replacing the projector diode array, it'd cost you less to just buy a new one.

If the manufacturer is so incompetent that it must rely on red-teaming members of laser forums for their design direction, we have nothing to worry about.

Default Re: Casio seems to be potting projectors

I agree w/BB
Companies routinely replace items rather than repair- good for the Co. image- quicker resolution and a much happier customer in the long run.

AixiZ Lasers sometimes just takes the word of a customer and replaces items without the need to return the defective/broken one. Especialy if that customer is a repeat customer.

Well, in the case of SE & NJoy vs FDA the FDA quoted directly from the forums of users, using their own statements, and it is now in Appeals of the Supreme Court thanks to those quotes. The forum Admins and mods asked that nothing negative be posted, but the constant influx of newbies wasn't controllable with their comments. They(the FDA) have the "deep pockets" on their side and the FDA cannot be sued, even monetary damages.

I see laserists as mosquitoes at Disney World. They are a pest that isn't wanted, but the bite from one with a disease would be trouble they don't want.

We could banter "what ifs" till the cows come home, but it will be what it will be.

Default Re: ***** seems to be potting projectors

Sure, here is where the many thousand post 1st thread was stopped, a new one started, and then they started censoring comments to boot. It was getting way out of hand.
I think the request for no negative info and the FDA using direct quotes and such is in both parts. Its a loooooooooong read.
SE, NJoy vs FDA -- Discussion

The FDA lost round one with Judge Leon, filed an appeal, and went on holding businesses product from China, in customs, driving them out of business with nothing to sell. They had no jurisdiction to do this and when a suit was sought against the FDA it was discovered they cannot be sued for damages, real or monetary, under any circumstances. They can spend all the tax $'s and backers $ they want and never lose. The only thing you can win from them is the right to continue on.

I have continued to harvest a number of these from buy.com, overstock.com, and newegg, and have not encountered any potted arrays.

I have encountered the triwing screws, thread locker, and the "e-torx" looking screws.
