CRE X1000 Worlds First 3 LED 3 LCD 1080p Projector..Anybody heard of these guys? - Page 8

I understand what you are saying. However I find it hard to beleive. I know that the reason for the blue screen burns on LCD projectors is the amount of light bombarding the Blue screen and polarizer. The conventional opinion is the culprit is the UV light but there may be more to it. I would like to see a screen shot with the yellow spots that sellmejunk is talking about and find out if they are getting bigger. Since these units have just come out the people who are buying them are in essence beta testers. They may have to put some sort of filter in front the blue screen to tamp it down a bit and crank up the airflow in the light block to keep any stagnent light from building up heat. This is only speculation on my part but it makes sence. So far this unit has been pretty impressive all things considered but this could be it's fatal Flaw. They seem to have the brightness issue under control and at this price it may be worth the dimness trade off. However if the yellow screen issue is this apparent this close to the purchase date there is Gonna be a HUGE problem

Ok heres a picture and short clip of the problem which has manifested, either thu smoking organic tobacco, or by some issue with overheating or whatever.

I`m hoping someone can identify what could cause this



Clip is here

Hans did in fact reply, asking for a photo to show the engineer & to enquire if the projector is anti-smoke or not.

Dunno what to expect now, hopefully i can get an exchange on a new one, or if they would repair mine.

Anyone recommend a smoke box place online that has something to fit this? Big screen film is so much better with a cigarette, living out the smokey cinema dream.

yeh i should cut down but what ya gonna do.

Sorry Dude, I truly am. I Really HOPE that I am dead wrong but that looks like a classic Blue screen/Polarizer burn. I have spent well over an hour trying to find some of the Photos I have on My computer of a burnt screen projection image but I can't find them. I did the second best thing and napped one from the net.
If I were you I would STILL QUIT smoking, but I wouldn't blame this on the smoking. IMO The unit is going to have to go back and needs a design change. Either they are going to have to
1 put a better polarizer before the panel
2 increase the air flow around the LCDs
3 decrease the voltage and light output for the blue panel
4 all of the above

I don't think smoke is the problem. I think heat is what caused the problem.

sellmejunk >>> Thinking back now, all those times you had your CRE X1000 turned continuously ON for hours at a time, did you ever happen to touch the panel at different areas just to "feel" how warm/hot it felt ? Any mention in the manual about cleaning air intake vents or how many hours the pj can run safely uninterrupted ?
I would say that if at any point you felt the pj's case as being uncomfortably hot to the touch, that would be cause for concern.
I also think that this doesn't look like it came from smoking cigarettes; The yellow stain is concentrated only in the middle of the screen and i'd imagine that smoke from cigarette would be more diffuse all over the screen.
Now if the problem is from overheating issues causing LCD panel degradation and this being an Epson D7 LCD panel that has inorganic compounds, the pj being brand-new as well as using LEDs for illumination that run cooler than standard bulbs, then what is going on here ?
Anyway, i think that Hans will take care of you to your satisfaction, especially now that there is at least one store here in the US that is selling this pj and i am sure that he would stand behind his company's products and reputation if he is to keep a customer base in the USA.
People all over do read these AVS Forums; Quite often when i google for some specific A/V info some of the first links i get are for AVS Forums...

It definitely looks like something overheated. Smoking wouldn't cause that. Did you have the projector well ventilated? These need plenty of room to get rid of heat.

In the first clip SMJ posted it looks like he has the projector on some sort of rack. It is hard to see if the rack is up against a wall or set in such a way that heat can build up and be sucked back into the projector. Either way something here is not right with a machine that has a lamp life of 60K hours and develops this kind of trouble from the get go. As far as I understand this machine is NOT supposed to have Polarizers because the LED's themselves are colored. I find it very hard to believe that they can make standalone LEDs that would not require some SORT of Polarizers between them and the LCD panels themselves. If this is actually the case then they will need to modify the design since it appears that the Blue Panel or something is getting cooked.
Here is a repost of a LCD block with a Burnt out panel to save going back a few pages. Look at the burn mark on the polarizer.

On a different topic action/Jackson?? Are you familiar with a company called Nfusion? and dummy2??

Chinese company nobody has heard of makes a cheap projector out of crap components and it isn't super reliable.... shocker !

Do I detect a note of Cynicism in your comment?? Nah!!

Bohanna

No, not that I recall. What is their field of expertise?

On the topic of the projector failing, I wonder if they implemented a sufficient cooling system? From what I have gathered, these LCDs put off a sizable amount of heat that must be dissipated through the heat sink.

Also the projector will only last as long as it's weakest link. In this projector, the fan appears to be the weakest link, as fans generally don't last 60,000 hours, more like 10,000. Smellmejunk mentioned that the fan was louder than before. I wonder if the fan may be failing prematurely?

In the video I posted last night, there is mention of how important the cooling is in concern with the life expectant of the LED bulb. It mentions that just a 20 degree Celsius difference could reduce the life of the bulb in half.

a tad bit... Not trying to be an a*s, but who has ever heard of this company? Why would we assume they are making a solid, reliable product?

This is very true

A lot of the projectors from name brand companies are made in China and I don't know the names of any of those Chinese companies either.

Who, foxconn?

I hate to say I told you so but if you go back a bit In several posts I have been harping on the inorganic panel issue with a wait and see attitude. Turns out I may be correct. I believe the LED's do run considerably cooler than the Metal Halide lamps but the halides output is cut in three when it comes to light going through the Panels. Bottom line,,,, I believe they will have to increase the polarization of light before it hits the panels especially the blue one or there will be a LOT of these going back for service and retrofits. This is gonna reduce the output of the projector which is not all that bright to begin with.

My guess is the fix is going to involve a spacer and a new polarizer between the LED and the Blue panel with a re-alignment of the screen and a firmware update to increase the fan speed and lengthen the cooling fan shut down cycle time, If I owned one of these I would have a boxer fan mounted outside the case blowing air away from the unit at all times.

Delta, Chillin,
Contract plants for Epson, Mits, etc. and not just China tawain, etc.

Well, looks like I can cross this projector off my short list.

Who knows they may work the bugs out on this one and it will be good to go.

My issue is that I need a pretty bright projector since I watch Football and some other things during the day. I have several other issues with Home theatre Vrs Business and the specks which I think are misleading.

FYI,, On the nfusion and dummy2 comment,,, I was referring to a Satellite Box newsgroup. There is a guy there named actionjackson and I was wondering if you were the same guy

Bohanna

sellmejunk, please, open this amazing box

Really?? VSW??? SMJ has been Great in letting folks in here see this projector put through its paces and you piss all over him? He is the kind of guy who took a chance and put his money where his mouth is. He took the freaking time to document it all for the rest of us and probably saved a lot of people a lot of grief and frustration. Ramdom Gloating over anothers troubles is the sign of a insecure sick mind. I hope the karma gremlins pay you a visit and show YOU the same level of consideration you have shown for SMJ.

P.S FOAD

Do you know if the scan lines in the scene changes are from the projector or from the camera that took them??? I understand avatar is a tech marvel but IMO there is WAY to much blue in it and the video clips that I am seeing look washed out with a strong blue hue and little else. I am alway a little suspisious when anything other than real life video is used as an example. Computer generated cartoons are not what to use as an example as they have no real flesh tone or natural color.

Bohanna

I don't, sorry. This was sent from Mr. Hans at CRE, from one of his customers in Australia.

What ive seen of this projector i really enjoyed it!
It hasnt put me off this amazing bit of kit.
After looking around reading forums, it seems i may have overused the projector & didnt have the area well ventilated enough.
If this is the case of overheating,,,then a CRE X1000 is a modders dream, as respectably enough the picture is above amazing quality to warrant spending a little extra to keep the projector running cool.

Looking back at it, yes the projector gave out alot of heat. and the air flow was probably not adequate enough as i had the projector up high about 11 inches away from a wall
& 22 inches from the ceiling & 4ft away from the corner walls. The corner was pretty warm,

The projector was seeing 5-6 hours every evening.On the weekend that projector was running at over 9 +hours straight.

Its partly because of the american site selling these promote it by saying 7-8 hours effortlessly, but also i guess most USA home have air conditioning? so would be cooler. dunno

I`m thinking when i get my next CRE X1000 i`m gonna build a DIY airflow case, and stick a bunch of PC fans on the inlet + exhaust to cool that sucker.

I`m un-detered very much looking forward to my next CRE X1000.

OK, you used it a lot in an area without the very best airflow - exactly a typical scenario. The machine looks interesting, but they really have to workout cooling issues. That should never happen in a production unit that is only a month or 2 old.

Sellmejunk: NOT YOUR FAULT

some of what you say is true; but that does not mean it is your fault. The projector design is not good if it cannot do what it is supposed to period! I have had projectors on all day with no issue what so ever.

Where do you live ?

IN order to increase efficiency you have to have the light source close to the LCD panel. The closer you get to it the greater chance of a burn in. These NEW inorganic LCD's are NOT supposed to break down like traditional panels. My guess is when they engineered the projector they thought this wasn't going to be an issue.,,,,, Looks like they were wrong. My guess is there will be a LOT of discussions relating to the panels and polarizers. There are some questions relating to if there are actual polarizer in this projectors or if the light source is colored and needs no polarizers. I think there is one and it has cooked . If not the panel itself has cooked. The other issue is the amount of heat this little sucker puts out. One of the things that people in the Home theatre market complain about a lot is fan noise. I believe that they can solve this little issue by kicking up the fan speed so the unit will cool better.

Bohanna

SMJ, seems like you had the projector set-up to allow enough ventilation, I would not think it would be your fault. I hope you get this issue resolved and are able to get back to enjoying your projector. Have you made arrangements to return it yet? Are they standing behind their warranty?

I agree. From his description it sounds like the projector had adequate space for cooling.

Yeah you have way more space than my HD 20 has. Its only 8 inches from the back wall of my room and 3 inches from the ceiling.
