Or should I go with OEM. Benq site has lamp for $199.00 where the amazon one is only $109.... Any suggestions?
When it comes to lamps I’d highly recommended going with the original manufacturer. Off-brand bulbs will work but generally the reviews will say that they're not as bright right from start and they don't last as long. I replaced my W1070 bulb with a BenQ bulb and for me it was worth the premium.

Also, I would highly doubt the veracity of many of the reviews of that lamp on Amazon. Some real gems here, lol:

I makes me feel very satisfied with such pleasant purchasing
By Shannonon December 4, 2017
Verified Purchase
At first, I must make confirm that this lamp I received very soon. I makes me feel very satisfied with such pleasant purchasing.
The lamp is working well with my projector and performances its great functioning.
Very happy to share with such great product.

Always believe the OEM one is the best,but I could try the replacement..
By Kim Rodanoon June 6, 2017
I spent much money on purchasing original product cause I always trust they are high qualified.
Couple days ago my bulb blew out,my friend told me that the replacement bulb from this company is reliable,durable
I would choose to purchase one for having a try.

Suggested to others
By Amazon Customer on July 25, 2017
I make sure this is an excellent lamp I had found. I am very interested in researching such kind of product.
I could easily tell from the badness and goodness.

At $200, do you replace the bulb or get a new projector?

Those are some chinglish reviews. Most likely, the seller wrote them, via Google translator.

I've bought my last two bulbs from AliExpress (and there's another on the way so I have a spare - waiting 2-3 months for a bulb when you have none is hell!).

There is the usual crap there but you can buy ones that are identical to the bulb that came with it, and I do mean identical. I made the mistake of getting the crappy copies from Amazon (UK) and after sending back the third one started looking elsewhere.

I don't know if I can name AliExpress sellers here so I won't, but you can tell from the pictures and the reviews that they are the real thing. The one on the way is the full housing, I don't know how I missed that the first two times and bought the bare bulbs :/ Be interesting to see how original the housing is as I've bought "original bulb custom housing" from the UK before and the housing didn't fit (but again the bulb was the real deal).

Anyway, just my 2c.

So bare bulb vs bulb kit?

I need to make a decision in the next month whether to replace my 1070 bulb or buy the Optoma 4k UHD51.

Leaning towards the latter but probably will keep the 1070 so will need to replace regardless.

If the W1070 is only going to be a backup projector, just get the CTLAMP including module from Amazon for $45. I used two of them and they were fine -- not quite as bright and the first only lasted 2500 hours while the second is still fine and has about 100 hrs so far. My W1070 is now my backup for my HT2050A.

My lamp came in today from Benq. I ended up not cheaping out and going with Benq. It was $215.00 including tax here in Cali. My original lamp blow up last week. After installing the new lamp i went to see how many hours i got from the first lamp. End up with only 3822hr. Kinda bum, cause from day one I set my 1070 to eco mode and only got 3800 even tho its rated to get 6000 hours....

Only? That's about what I got on original bulb and a 45.00 bulb got me almost there on next bulb.

yeah seriously I didnt realize how little I was using it lately mainly cause I was getting so used to deeper blacks and contrast from other displays that it was affecting my enjoyment of it unfortunately. Plus it was dedicated to movies only so that helped keep the hours low.

so my projector has been getting a red light lately and shutting down. I can usually turn it back on after a short break and it will work but it is becoming more frequent.

The fan is very noisy lately as well.

Is this red light/shut down a sign of a bad fan or that the bulb is going bad/overheating ?

Im kinda leaning toward the fan since it is very noisy when it shuts down so can you just replace it ? or maybe add an external fan to blow cooler air into the projector ?

I have had the projector for about 5 years so i know the bulb is getting old so i guess it could be that too, not sure.

Hi,

Have you tried an input other than HDMI?

Which light is red? Is it 'power', 'lamp' or 'temp'?

If the fan is noisy then it's probably having a hard time spinning, and not spinning within the necessary speed interval (+/- 20% of its programmed speed), so it would probably be worth to clean or, if it's really faulty, replace that fan.

Thanks - I didn't realize until after I quoted that it could have been more than 1 light so I will have to check next time it goes on.

Do we know what size fan is inside and if it easy to replace ?

It usually goes by the model, not by the size. You have to search for that fan by the model of the projector or of the actual fan. I would first try to clean it with compressed air, and only then replace it if necessary. Removing fans is relatively simple if you're technically inclined; don't try it if you're not.


Here's the service manual, which should give you some guidance:

thanks I did manage to get most of the fans cleaned out and it seems to be working a lot better now.

one thing though - I did use some compressed air in the body of the projector and now I have spots all over the screen which I assume is dust that got into the lens or color wheel.

Is there a good/easy way of getting this cleaned up ?

To change the color wheel on the W1070 I need to remove the two screws facing the back of the box on the housing, correct? So, use a either right angle screw driver or take the circuit board off?

I've found a replacement on ebay, based on the part # I read on the wiring (QISDA-102418672).

Does anyone know if other color wheels fit and if so which ones?

The used ebay item is $49 and free ship. Has anyone priced these from BenQ in Chino, CA?

Any help appreciated.

It's not the colour wheel the problem but the DMD now has flecks of dust on it. The optical cavity isn't actually sealed on these projectors so compressed air cans should be avoided at all costs. Tip: never hold the can upside down or fire it for too long, because liquid comes out and that is a nightmare to remove. You can first try opening up the exhaust port on the optical assembly (a small screw holding a flap to the side of the lens shift screw), and fire a couple quick blasts in there, it might work well enough.

I did the same thing and had to wipe the DMD by opening up the entire projector. It is a royal pain, trust me, because you won't know if there are new flecks on the DMD until after you close it all up again and fire it up, which can take a while. All told, it took me about a dozen times before I got it perfect with no splotches or smears on the projected image. Beware, if you walk down this path, madness and frustration awaits you. Abandon all hope ye who enter here.

You could instead try sending it in the BenQ to do it but there's no guarantee they will, even if it's under warranty. They might.

BattleAxeVR - I cant thank you enough for this post !

I decided to open up my projector again and followed the owners manual as to how to take it apart properly.

But i wouldnt have know what to look for and what to do if you didnt mention the DMD.

Found the DMD with the help of the manual and wiped it clean with a cotton swab. Swabbed what i guess is the mirrors as well and also cleaned up the blower fan which i didnt get to last time.

Everything is working great now and no more spots !!

Thanks again for the post !!

Here goes:

I own a W1070+ Benq beamer and everything has been working fine for 2 years.
Just yesterday my HDMI switch broke down, so I needed to plug in everything manually. Now here's the thing: only some of my devices are displaying.
My laptop & Playstation 4 display nothing , but the HDMI signal does light up green.
My TV box's signal switches on & off every 2 seconds.
My Raspberry Pi is the only thing that works perfectly.

I've tried many different HDMI cables (long & short) , I've tried factory resetten the beamer, i've tried unplugging the beamer for 10minutes (and also the other devices).

Now i'm out of ideas.. The only thing I found on the internet is that maybe my hdmi switch was responsible for ignoring the HDCP signal which is why everything worked ? I don't know..

Sigh..

Can you maybe PM me which which bulb you bought from ali express or can you point me in the right direction? My current W1070 bulp is at over 6000 hours at the moment and i notice the picture getting weaker. I think i need the full housing.

Thanks in advance

My Benq W1070 was bad about locking on to weak HDMI signals. I finally had to bypass my AV Receiver and buy a separate HDMI Switch which put out a stronger signal. I don't think your switch was stripping the HDCP, it just worked because it put out a stronger signal.
