Blown bulb in W1070, replace or upgrade?

So I was watching some football yesterday when I heard a loud pop then darkness I knew right away the bulb just blew in my Ben Q W1070. I have had 3-4 projectors over the last 15 years and this is the first time a bulb has blown. It was the 2nd bulb I have had with this projector. So I took out the bulb and housing. I did see a bunch of glass pieces inside the projector. I cleaned out what I could find and ordered a new bulb. But I am wondering if that is the best course of action at this point? I purchased it in March of 2014. It has thousands of hours on it. First bulb I used until warning, reset it and used till next warning. I then replaced bulb and did the same thing, this time it bit me though. So it probably has 15-20k hours on it.

Replacement is going to cost about $130. Wondering if something like a HT1070 at $500 or HT2050 at $750 would make more sense? It sucks we just aren't there yet with 4K as I would love a 4K projector but the options are slim and around $2000-3000. I also don't think at this point it makes sense to spend $1500+ on something like the Sony HW45ES with good 4k options probably 1-2 years away.

If there is no damage from the blown bulb, I suppose I could get another 1-2 years out of it if I am lucky then reevaluate. Are the 2 options I listed solid upgrades from the W1070 or very similar? Thanks.

I would replace the lamp. Typical damage from a exploded lamp is glass getting into the lower squirrel cage fan and requires a complete tear down to clean it out. As long as that has not happened you should be good to go,but if it has and you don't have the skills to clean it out it could get rather expensive.

So I ordered a new bulb. It arrived today. I installed the build, hooked up the projector and have issues.

The projectors starts up as normal. After about 45 seconds the picture just starts flickering weird colors. After about 10 seconds of that the picture cuts out and the red lamp light comes on. Restarting the projector just causes the same process to repeat itself.

I purchased a highly rated and one of the more costly bulbs on amazon. Could this be an issue with the new bulb or is it more likely the projector was damaged when the bulb blew? I really did not want to have to go buy a new projector right now.

I had seen some small glass shards in the projector which i cleaned out. I light shaking of the unit does not reveal any rattling to indicate there are more floating around.

Amazon ratings and higher prices are not guarantees of "compatible" replacement lamp performance. The only way to be sure whether your issue is related to the new lamp or to leftover effects of the previous lamp failure is to see what the projector does with a genuine new replacement lamp installed. Unfortunately a new genuine W1070 replacement lamp direct from BenQ is currently selling for $245, which is half the cost of a brand new BenQ HT1070, and there's no guarantee that the lamp itself is the issue. Tough call to make.

Well I am not sure its the bulb. Looking at causes for the red light it seems if the fan is blocked the red light will come on after 3 mins or so. Mine goes in less than a minute and I get lots of weird colors flicking on the screen for 10 seconds before the unit shuts down. I am guessing something else got damaged when the bulb blew. Which means I am probably looking for an upgrade at this point

So I think there are 3 options that make most sense.

1. Get the HT1070 at $500 - basically the same projector, don't think there is any improvements?
2. Get the HT2050 at $750 - small upgrade, mount in same location, familiar.
3. Get the Epson 3100 - $1100 - big price jump, more lumens, should have better contrast, longer warranty, cheaper bulbs.

I have a fully light controlled theater so not sure i need the extra lumens of the Epson, but always nice to have more as the bulb ages. Not sure on going to 3LCD from DLP. Err I hate these decisions.

From your description sounds like glass shards have either damaged or are just lodged in the color wheel. Doesn't require a complete disassembly to get at but some skills are required. If you don't need the lens shift of the Epson and were happy with the older BenQ the HT1070 looks like a good option so tough call.

If you're going the new projector route, it might be worth looking at the new HT1070a that just shipped this month. It's basically a rebranded W1070 with marginally better contrast and brightness (2200 lumens). Bulbs are cheaper too which is always a bonus.

Hmm did not know about the HT1070a. Looks very similar to the HT2050. Same lumens and contrast. Is the only difference the HT2050 has a glass lens?

These new models feature the same glass lens as the HT2050.

In Europe, the HT1070a is known as the W1050. I read a German tech review that claims the projector throws one of the sharpest images they've ever seen, and is by far "best in class" in it's price range. They also measure peak lumens at 2293 in Bright Mode, 1672 in Vivid and 1022 in Cinema. For comparison, Vivid mode is known as Standard mode on the W1070.

@marjen , the HT2050 has a larger case with more internal baffling which makes fan noise a little quieter than the HT1070/HT1070A. The HT2050 also has a few inches of vertical lens shift which the HT1070/HT1070A lack. But the HT1070/HT1070A are already pretty quiet in low fan mode and you can make up for the lack of lens shift by taking the time to mount in the optimum position or getting a fully adjustable projector mount.

While the HT1070A has minor improvements the HT1070 is currently available at a much lower price on closeout sale to clear stock. It should also be noted that the HT1070A only has a 1.2x zoom (1.28-1.56 throw ratio) while the HT1070 has a 1.3x zoom (1.15~1.5 throw ratio). So they produce different image sizes at different distances, which will be more important to some than others. For example the closest an HT1070A can be to throw a 120" image is 11' 2" while the HT1070 can be as close as 10'.

I don't think everyone has noticed this change in throw ratio which effectively makes the HT1070A a longer throw model than the HT1070. This is important for those who want to throw larger images in smaller rooms.

So if the HT1070a has a Glass Lens and 2200 lumens and 15000 contrast, those are all same specs as the HT2050 for 100 less. If that’s the case I might jump on that one.

It's been noted in other threads that the HT2050 is showing up on some sites as "discontinued" and the HT3050 is showing up with an msrp reduced $100. So it may be that BenQ is reshuffling the lineup with the HT1070A moving up in quality over the HT1070 and the HT3050 moving down in price to fill the space previously occupied by the HT2050. Or there may be an HT2050 replacement coming. We're still speculating.

Ordered the HT1070a as a replacement. Came in yesterday, got it plugged in and in the position of my W1070. I need to move this back about 2-3 feet to get the same images size. I am surprised if anything I thought it would be the same or shorter throw, not longer. No real time to get it dialed in yet but plenty bright (overly so) in my darkened theater. I seem to be having an issue getting it into the eco or smart eco modes. No matter what I do when I return to the menu its always on normal. Nice sharp picture. Still can't find any confirmation it has a glass lens.

Marjen, what are your impressions of the 1070a so far?

Well so far I guess it seems similar to the W1070. Contrast I believe looks a little better. Its also brighter at the moment due to new bulb. It does seem a little louder as I am not sure its in the right bulb mode. I keep trying to change it to eco or smart eco and it does not seem to take. The throw is also longer than the W0170. Had to move the projector back about 2 ft to get the same size image. I will say i think it looks a bit sharper, but really can't say for sure.

I don't think a lot of people have yet caught up with the fact that the HT1070A has a longer throw than the W1070, HT1075, HT1070, HT2050, etc. Be sure to check one of the projection calculators before assuming that you can throw, for example, a 120" image from as close as 10' like the older models. The HT1070A requires a minimum 11' 11" throw for a 120" image. The HT1070A also has only a 1.2x zoom compared to 1.3x for the older models.

I noticed when I first got my W1070 that it had to be running for a few minutes before it would allow the lamp power to be changed. But it was at least greyed out. Maybe the 1070A firmware is not really accepting the change, but not greying out the option so you know it won't accept it ? Have you gone back and changed it after it has been running for a while and it still doesn't take ? Does it keep your other changes to color and brightness and contrast settings ? Is there some other feature that takes precedence and requires the full lamp -- like Vivid or Game or Sports display mode or something ?

The different throw and zoom ranges are disappointing. Those seem to be the same as the older Optoma projectors and are one reason why I chose Benq W1070.
