Who has the best colour wheel bearing quality

post #1 of 13
Thread Starter 
Hi there. I need an opinion or someone to say that I am on the right tracks with my research for a new proj if possible.

I have been using an XGA DLP now for years for HT home use (non smoking living room atmosphere). I tend to have it turned on every night and weekends for TV, XBox 360 and PC.
I originally bought a Dell 3200MP and the thing lasted 10 months before I got the color wheel scream or grind.
It was still in warranty and I swapped it for another 3200MP. That lasted 11 months.
I swapped again but this time they upgraded for a 3300MP (new)
That lasted 11 months and I swapped for a refurbed 3300MP.
That lasted 11 months and I swapped again for another 3300MP (new).
This one (still a 3300MP) has lasted longer (16 months) and it is now starting to scream again, but now my warranty has run out.

So I am on my fifth (or sixth, I lose count) DELL projector and I have only had to change the bulb once. I found it a little wierd that a projector couldnt outlast the bulb in a normal not too dusty, non smoking, living room environment, but before because it was always in warranty I didnt mind.

So now I need to buy a new one because DELL will definately not swap it again.
I dont want an LCD proj because I do like the detail of a DLP. The PC links up lovely on the native XGA at 1024x768 and I dont think LCD will cut it for me.

Hating the idea of the colour wheel going wrong again I stumbled upon the Casio XJ-A240 range and thought my problems had been solved (A DLP with Laser and LED technology bypassing the need to split the white light to RGB) however after reading the extensive post here:
SORRY NO URLS ALLOWED but it is the post discussing the Casio XJ series of LED DLPs

I now understand that they do in fact still use a colour wheel to pass the blue laser through phosphour to get the green for the RGB. So I am steering well clear of those for now at least until they have two blue lasers, and lose the colour wheel.

I do however think that the LED DLP will get there, it may just be a couple of years before the 1080p 3D ready LED DLP will be within my price range (£1,000)
So for that reason I need a good low priced (under 1k) DLP proj to tide me over, but I dont want to fall in the trap of another make that uses poor colour wheel bearings.

When trying to Google for quality color wheels and other searches it does seem to point to the fact that Samsung looks pretty much as bad as the DELL when it comes to getting a projector with frequent use to get its colour wheel to outlast the bulb.

I have seen some good Optoma HD series on ebay (I like the look of the HD70 or even older HD65) but I was wondering if anyone can confirm for me that I should have more luck with this or is there a known projector make that is low budget but still uses good quality color wheel bearings and parts?

Cheers for reading this far, and I hope this post may help others who search in future, because I couldnt find the answer to this specific question on here.

Unfortunately you are limited by budget more than anything. In that general price range, quality is going to suffer. Now admittedly your Dell experience is a bit extreme, but still, color wheels are often the first thing to go on DLP's...

Hi Jason. Cheers for the reply.

Yeah I understand I am in the budget bin for this one.
A couple of years back I was holding out for the 3 laser DLP because I understand I am what is termed a heavy user, but now understand that because of possible retina burn that they will never appear for front projection systems.
I was actually surprised that the Casio is allowed with blue laser and red LED but I guess the blue laser isnt an issue for retina burn. Anyways I digress.
I think that by holding out for a while then the LED systems will soon get to a stage where I can do away with colour wheels and bulb replacements (and hopefully quieter cooling fans) but I dont think my current DELL will hold out that long until a suitable LED system comes out.

So looking at the £1,000 or $1,500 budget single chip DLPs I guess I am after opinions on quality of color wheel bearings for the following makes:

Optoma,
Infocus,
Mitsubishi,
Hitachi,
BenQ,
Epson,
Samsung (I think I have found these are pretty poor)


I think I am moving towards the Optoma HD20, because it has the RGB, VGA, SVid, Comp, and HDMI ports so takes the lot of my toys in one go without having to switch leads.
There are loads of threads on here about replacing colour wheels, and loads of threads about symptoms of colour wheel bearings going wrong, but I hope by raising this post then in future there will be a reference people can use for customer experience of bearing scream in different makes.
By the way I say Dell 3200MP and 3300MP are not good for colour wheel scream. As you mention my experience is a bit extreme, but it is always under the 2 year mark and has happened time after time for me so I think I can say my conclusion is those projectors used for over 6 hours a day use will not out last their first bulb (in eco mode).

Cheers again,

Lins.

ooh, I will keep looking around here and pooling my results, but I have just found in the post title:
Comparison: 720p projectors such as IN72, HD70, HD1000U for budget projector
(cant post links yet)
there is the following comments:
I have read that HD70 owners have reported similar color wheel issues.

I know that isnt the HD20 but it does seem like Optoma may be starting to get a bit of a reputation for color wheel whine as well.

Right then lets see if I can find a similar reputation with the BenQ W600 or W1000.

Hi there, me again,

I want to keep posting my findings because the nearest post I can see that addresses this question is 2007 and so since the 720p range and above I think it is a valid question.

So:
I have elimianted the Optoma because back with the HD70 range they seemed to have the whine problem,

Earlier I eliminated the Samsung because there seems to be a flood of posts on how to replace the color wheels with those so I assume they have an issue with this.

I have eliminated the DELLs because of my own personal experience over the last 6 years.

I have now eliminated the Infocus because the X1 range and others seems to have a few reports that pops up of colour wheel whining getting worse.

So I think I am landing on the BenQ.
Specifically the W1000 although I may go the route of the W600 as I am happy with 720p instead of full 1080p.
Firstly to mention I looked in to LCD and saw the difference between W500 and W600 (LCD v DLP) and LCD also has its issues with dust blobs so I dont want to trade one issue with another (color wheel whine for dust blobs)

But yeah another reason for this is while reading up on replacing colour wheels it seems that a few home brew tinkerers have said that the motor and bearing for colour wheels are the same or similar to what is used in DVD drives.
Now BenQ makes DVD drives, they make loads of them for the XBox 360 (So do Hitachi I know I will be looking into them next). So this leads me to think that they are most probably the best ones to design and fix the colour wheel bearing because they dont buy this part in.

So yeah, currently my best option I think is the BenQ W600, I think it pips the Optoma HD20, HD70 and HD65 to the post.

Look for a used Marantz. You might be able to find a VP-12S4 for near $1000.

For what its worth, my Mitsubishi HD1000 is just under 4 years old and has over 8000 hours on it.... I can no longer get my people to use a TV so the projector is on anytime someone is home... Our environment is pretty dusty, enough so that having an LCD worries me due to their dust blob issues. It hangs almost directly over my favorite viewing position, and after 4 years if I mute the sound I can faintly hear the fan running...

Again though, what you are going to find is similar to your findings with the Dell...the color wheels go bad. Sure some are worse than others, but ultimately that is a common source of failure.
post #9 of 13
Any other companies make the color wheels in addition to Texas Instruments and BenQ?
post #10 of 13
I am surprised that over the years you managed to have so many color wheel barings failing on you as i remember reading some years ago that color wheels have an estimated life time of at least 25.000 hours.
On the other hand, if you are so satisfied with native XGA connected to your computer and considering your "history" with color wheels, why not kill both birds simultaneously and get the LG HX300G, which uses a trio of LED chipsets from Luminus Devices (rated by different pj manufacturers anywhere from 20.000 to 60.000 hours), NO color wheel, almost non-exhisting rainbows, amazing colors due to those LEDs, native XGA, all controls necessary for adjusting overall color/contrast/brightness performance, a pj that hardly gets warm to the touch after hours of being turned on, almost instant on/off switching, HDMI + USB + RGB inputs, etc, all in a package that is barely larger than my hands; Its liabilities would be maximum recommended screen size at 96" diagonal and lumen output of 300 lumens.
You should check out the thread on the LG HX300G to get an idea of its capabilites and limitations....

Hi MCaugusto cheers for the advice, although I have had a look at LED and they dont look bright enough yet for full daytime use.
I want at least 1500 lumens and 1000:1 CR minimum for daytime TV viewing.
That is why the only LED one that looked to come close to that was going to be the new casio XJ range (mixed LED and laser) but of course as I mentioned they still use a colour wheel.

I want to stick with DLP because I have found through research as you say that they supposedly should last longer and that is why I think this is more of a Dell issue rather than a colour wheel issue in general.
I also think business and others that tend to use Dells wont of had them on 6 hours a day, every day like me and that is why I am one of the few that has had this problem repeating because of the constant use I put it through.

So yeah for that reason I think it is going to be a BenQ W600 or W1000, I may go for the W600 just because yeah I am happy with 720p and it is a stop gap fo ra couple of years until LED does get to 2000 lumens

Cheers all, the last few days has been a real education fo rme again and I feel I have caught up with where we are at again in terms of projector techynology.

Did you know that the w600 is replaced by the W600+
and the w1000 is replaced by the w1000+?

Thought you should know
post #13 of 13
Speaking of color wheels, those found in the BenQs are extremely slow by today's standards. The W1000 and W600 are 2x and the W1000+ (and, I assume, the W600+) are 3x.

I don't think I could live with that. 4x is a bare minimum.
