BENQ W1070 Disassembly - Changing Lamp and Cleaning Blower Fan After Light Exploded
Вставка
- Опубліковано 20 сер 2024
- I had the light bulb explode in my BENQ W1070 projector that I use in my media room for both watching movies and sometimes for gaming. After purchasing a new light, the W1070 projector would overheat after a few minutes and turn off.
The problem was that pieces of glass got sucked into the center blower fan, which requires taking most of the projector apart. Since I couldn't find a video of anyone else doing this I thought I'd quickly film how I took it apart and cleaned out the blower and then reassembled the unit into perfect working condition.
Overall this is a great 1080p projector for any media room and I would highly suggest it, although if you are in the market for a new one there is a newer HT2050 or HT3050 out for purchase from BenQ now (links to those below):

As everybody else in the comments, thank you! Even 7 years later, your videos keeps helping people! ;)
People like you make the internet great. Had the same problem but would have never dared to take it apart without your guidance.
I’m still nervous to take it apart LOL
Absolutely brilliant and such a perfect and unselfish antidote to all the vile hate on the internet. This is exactly what happened to my projector. I followed your instructions despite being a bit daunted by how complex it looked to do. Found the fan, opened it up and removed secveral chunks of bulb glass. Working once more. Very satisfying thanks to you taking the time to post up this. Thanks once more.
Thank you so much, fixed my W1070+. The bulb exploded 6 months ago but we removed it for cleaning, when we reinstalled it. It came up with the same error code after 3 minutes. After taking the fan out and cleaning it. The projector worked as good as new. Thank you!
Just wanted to say thank you like so many other people here. This was exactly my problem and I was ready to bin the projector. With little experience and watching the video I did pull it all apart and there was a lot of dust and two glass fragments in the fan. Great video and this should give me another 4000hrs of viewing. Well done.
Thank you times a hundred. This gave me the confidence to dive in and fix this issue. I would have never known where “fan 3” was.
Just had mine fail in the same way - bulb burst, replaced, fan failure. Followed this video and I am back in business. Many thanks!
I had the exact same issue and your video helped me a lot! I would not consider myself very skilled when it comes to technical stuff but now I feel like Howard Wolowitz... :D I just finished reassembling the projector and so far it seems to work! Thank you very much!
Thanks for the video. My BenQ is up and running again. Had a problem with vertical, white lines, but I gave it a few good bangs and now it works perfectly!
You saved my bacon!! New bulb was shutting down after 3 minutes. Found 5 pieces of glass in blower !!! Thanks !!!
Glad to have helped!
Thank you! You saved my projector! Really. I thought my hope was lost after asking for a replacement lamp and that one didn't work either..❤
I can't thank you enough for this great video! Obviously it solved my problem at the first try, and I would have never managed to dismount the projector by myself. Big thanks!!
As many others have told you before, Thank you very much. After eight years and a half, my bulb has explode and, I had the same "blower" issue that you explain in your video... thanks to which, i have just fix it, and (once cleaned of little crystal pieces) my projector is runing again... Thanks again, I hope it lasts for many more years
Thank you for the kind comment and I'm glad it's running! Since this video, I'm still using mine and so far it hasn't happened again, so I hope yours lasts just as long.
Thanks you very much for your encouragement.
I was in the same situation: exploded lamp, fitted a new one (Osram bulb only), after which the projector would not stay on for more than 3-5 minutes.
I did not really encounter much debris in the bottom fan, but I clean out all parts anyway.
During the first assembly I forgot to connect one cable, but after second attempt all seemed to work fine.
I'd say all in all this took me about 1-1.5 hours.
Great video! Just got done cleaning out my w1070 after a bulb popped. A couple comments....
1. The black "strap" on the corner of the PCB sits on TOP of the PCB. I noticed when you re-assembled you put it underneath the PCB. I doubt it is a problem, but just thought I should point it out.
2. A 5mm socket works perfectly for installing and removing the hex head screws around the VGA and RS232 ports.
Thanks for taking the time to make this video!
Great feedback! I hadn't noticed putting the black strap on top of the PCB, so great catch. And yes thank you, a 5mm socket would have been much more efficient than using the small pliers I used for those hex screws, great to know for anyone who's going to take their unit apart.
I was about to give up on my new bulb until I saw your video. My blower had glass stuck from the explosion. Thank you!
I was able to use this video for my BENQ MH630 Projector. Almost everything was the same throughout the process, aside from some wire connectors for fans and such. Much appreciated!
We had the same issue, but instead we turned our vacuum into a blower and blew into each vent opening. There were shards of glass and dust that came flying out. I would try this first before taking the projector apart.
Thanks OP for the video and insights!
I was literally thinking of exactly this before taking it apart. I’m terrified that i’ll fuck up in putting it back together. And i say that as a person whose not even too bad at doing stuff like this usually.
Thank you! My lamp also exploded and i had the exact same issue. Glass pieces were literally stuck in this fan and blocked it from turning. But thanks to your video i was able to fix the projector. Thx
I'm glad the video helped! Hopefully your projector is working like new :)
Sir, thank you for the vid.After more than 5000 hours my lamp exploded, i replaced it and had this heating issue. Checked the fans on the special menu and the third one was like "off". Teared the projector down thanks to your video, did a good cleaning of all the fans, found out some glass pieces were in this blower and blocked it, and i'm pleased to say my BenQ 1070w is as good as new =)
So glad to hear it!
Very helpful and solved the very same problem, amazed at how much dust was throughout the projector, gentle hoover worked well.
WHY isn't this video shipped with the projector?? Brilliant! Thank you so much!!
I had the same problem and couldn't find any solutions until I see the video clip. Thank you very much
Thank-you so much - A quick check in the secret menu (Menu then Source+Enter) proved that the inside fan was not spinning and your guide gave me the confidence to open it up and remove the glass in the fan. Mine was a HT1075 but the projector is near identical. THANKYOU!
Just followed your Video and repaired my W1070. Thanks a lot for putting this online! Damn hidden Fan3 - they really could have made that more accessible.
What also helped me was how to get into the Service menu to check the fan-Speed. Just select the last menu item (info) and press 3x up+down and then enter. In the Service menu on the 2nd item you can find the fan Speeds.
I agree, damn hidden small Fan3. Also it's surprising how even that small fan can affect temperature so greatly that the unit overheats within minutes.
Wow and thank you for the tid bit on how to check for the fan speeds, I didn't know that either. Glad you got your W1070 all fixed up!
@@NewbComputerBuild hi bro i have same problem on my w1070 projektor the lamp overheating so mach like a pan is this solution for me to? OR I HAAVE OTHER PROBLEM?
Thanks for the video. I had exactly the same problem. The lamp exploited. I changed the lamp but the projector was overheating after about 5min of using it. I had a piece of glass blocking the blower (fan 3). The fan was stuck with the glass debris. After cleaning it and reassemble the projector is working perfectly. Thank you!
Another happy viewer. Thanks for saving me the hassle of trying to send it in for repair.
Glad to hear it :)
@@NewbComputerBuild Was there mercury in the bulb? If so, did you expose yourself to it? Residue mercury still present will evaporate in the heat and the fan(s) will make it an airborne hazard. Best to run the projector outside for 10 mins and let it cool sufficiently.
You rock! Just solved the same bulb explosion / fan issue thanks to youtube saviors like you.
Oh man, I can't thank you enough. My bulb also exploded and I had glass in the blower fan. I was able to follow your video and solve the problem. Thank you so much for taking the time to make this video, you saved my ass.
You are very welcome.
Amazing, this fixed mine also. I din't have broken glass but just dusty fans in the end. If you have replaced your lamp and still the lamp light goes red (despite the new bulb), do this video!
Awesome video! Same here with the popped bulb. Took it apart and blew it all out. Fan speed now operating at target setpoint and projector functioning fine. Thanks for the assistance!
Thank you for making this video. My bulb popped this morning, so while I wait a few days for the replacement, I'm going to give this a shot, I don't want to take any chances with the new bulb.
Not a problem and I wish you luck and almost guarantee there is glass in the blower fan. And if not...at least you can get the clumps of dust out :)
Didn't get as many pieces as you did, but there were 2 good chunks of glass in there. Thanks again for the video! Now I just have to wait 2 more days for the replacement bulb to get here, but now I know it'll be protected by cleaned out fans
Awesome to hear, and even those 2 chunks of glass would have stopped the blower from spinning. Glad to have helped.
Dang it.....put the bulb back in, and now the projector won't even turn on. No lights or anything at all when I plug it in......any ideas?
Got it figured out. Back in business!!
Thank you! I also used this to fix my projector. I had no idea the exploding glass would do that.
I disassembled my projector as you did in this very video - in fact I had my laptop on the table while I did it and watched your video. But I have to say it's not that complicated - once you lose the fear before it, it's pretty straight forward (and backwards when you re-assemble it).
Unfortunately it doesn't fix MY problem, I still get the LAMP-error, so my hope is, that I bought a bad lamp and get a working one in return.
But no matter what the future will bring, I have to say, I'm pretty proud of myself that I did it (and it didn't explode on the first test) because 2 weks ago I would have never thought that I would be able to do that without destroying the entire thing :)
So thank you anyways :)
Did you get a new bulb? Did that fix the problem?
yes, but it's still broken ... must be something more difficult :(
I have the same projector and my bulb exploded a few weeks ago. I got about 3500 hours. But I decided to by a Chinese ebay cartridge for $70 rather than $300. It was flickering after 2 minutes and after a few experiments I found that it works only in Cinema Mode. If I change the option to Normal or Bright it flickers. Weird. I also had to clean a the shattered glass out of my unit too. Glad to hear that yours blew up too.
Common problem with the bulb, my last three bulbs did the same thing :(
Thanks for the video and the link to the manual, saved me a lot of time.
Glad to have helped! I'm surprised at how common of a problem this is.
As I was how easy the fix is. Thanks again!
Was also greatly helped by the video but due to sloppiness/tiredness I must have missed some ground connection or something so the projector was completely dead after reassembly. I had to do the complete teardown again and reassemble it very meticulously, and then it worked.
So please be careful to note which screws go where, which metal is supposed to touch and so on.
These idiots at benq should have directed me to this video. I called them and they were puzzled. Your video saved the day. Thank you very much. Almost gave up on the projector.
I follow your video and my Benq 1070 works again! Thanks
Thanks for this video. Finally, my beamer is also running again, same issue :)
Of course!
Thanks from me as well, had the same issue and now it is solved and it was much easier thanks to you!
So yeah same thing replaces bulb...thought I was screwed...saw this video and walla glass in blower. Just a tip when reassembling make sure all plugs are in secure or u will be reassembling :) thanks mate
i like videos where they talk... you know.. the process on how to fix things :)
Dude!!! Really works, exactly the same problem.
Thank you very much for the video.
Glad to have helped :)
How many hours did you guys have on the bulb when it "exploded" ? Mine is on 3200 ish hours now. I have always used eco mode. Maybe 100hours on regular mode.
Same exact problem happened with my w1080st. This was extremely helpful!
Thank you for posting this video. Just fixed my 1070.
This worked! You're a projector saver!
Thank you! I have the same problem with blocked fan. You have a beer from me :)
Thanks so much. This solved my problem with my new bulb!
You are very welcome!
followed your video to take unit apart and clean some dust off... awesome video except for some of the music halfway through.
anybody else has their housing get really hot? when I take cover off to remove bulb, the plastic on top was turning brown and broke off easily....
Thank you and what's wrong with this awesome creative commons music? haha. Sorry I'm not sure what would cause the housing to heat up to the extent it would brown the plastic top, sounds like an electrical problem.
Newb Computer Build
lol....I think I'm nearing 15k hours on the original bulb....
Great tutorial 👍🏻 is it just me or is the music KIND OF LOUD 🔊🔊🔊🔊
Kind of
Very helpful! Saved a lot of money. Thank you very much for the video!
You are very welcome!
thanks bro i followed your steps and fixed my projector, works perfect
No problem, glad it worked out :)
Thank you so much for this video, it was incredibly helpful. Exactly the same thing happened to me too and your video was a life (projector) saver :).
Glad the video helped and that the life of your projector has been saved :)
Amazing thank you so much for this!!!!! worked like a charm.
OMG ... my light bulb exploded last week, I ordered a new lamp and ... have the same problem. Projector starts but within a few seconds a get the LAMP signal and nothing happens.
So, it looks like I have to do the same as you did, thanks for the video because I really was like buying a new one and throwing away this one. But now I think I have to try this first ... I mean, after all, I can't make it any worse, can I? Even if it doesn't work (or I'm too dumb to get it reassembled) I'm at the same point as "I have to buy a new one" but THIS NOW is a chance to save a lot of money and getting back the projector I love so much.
Another question ... the fans at the side of the projector - aren't these "normal" fans that will also be used in computers? Haven't you thought about changing them with better fans (more powerful, more silent etc.)? Looks like there is room for optimization :)
Thanks to you I just fixed it !
Thanks.
Grate education, it help me alot
Thank you for you video. Also had the same problem, It's fixed now! Cheers
Glad you fixed it!
Did this and now it won’t power on at all. Taken it apart multiple times now to check everything but no luck. Anything I’m not seeing?
It works 🤘
Thank you so much, we follow your video and it worked.
Glad to have helped!
thank you! this is Exactly what happened to me. Perfect!
Cheers!
Same problem for me.. Fan 3 didn't move. It takes about 30-60minutes
Thanks mate! I has same problem
No problemo
I think to buy this projector. It's possible to reset time lamp in middle then when somebody buy hi think it's not so much hours. I seen in Amazon used benq with 1684h lamp
Thant you so much! From Tahiti.
Glad to have helped!
Worked for me aswell.
Thank you very much
Brilliant, many thanks, worked a treat
thanks! I had the same problem and this helped a lot
Thanks for making this video it really helped.
Just finished putting everything back together but now there seems to be no power to the projector itself🤦🏾♂️😩
I’m having trouble getting the front panel off and your video skips out actually getting off. Could you please help as that’s the bit I’m struggling with. Thanks a million
My ht2050/w1110 got bulb exploded too. Then I bought a new bulb and installed it myself. Then when I turned it on. It lasts about a minute or two. The image would go from dimmer greenish color to brighter with colors getting pronounced then it flicker. Flickering intensifies then it shuts down by itself. Can anybody help me clarify what's going on here?
I read that one should use a special mercury vacuum to get the glass pieces out. Couldn’t really make out what you did to get all the class out... any sort of vacuum or did you simply “shake” the glass out? Thanks having taken the time to make this video. Have yet to find out if I will have to go through this once my replacement lamp arrives...
I did this a bit ago, but honestly, I just shook. They all came out. I would not recommend spraying a dust can in there, that's where the danger lies as dust can get caught in the color wheel.
Newb Computer Build - ok thanks. Ended up shaking and vacuuming the inside and in the meantime my lamp arrived. Installed the lamp and all working well (so far). Have the feeling the projector is a tad bit louder than before however...
I reassembled the projector, I turned it on, the green light turns on and there is no image, does anyone have the same problem?
Merci infiniment, superbe video ! (Thank you so much, beautiful video!)
Nice video mate but didn't help me. mine turns on i green solid green light for 5-10 seconds then my RED lamp light comes on and stays there, fans are working. dunno what to do
help me please I opened up my projector because when I dropped my projector the glass from the bulb went in the blower fan and when I removed the glass and put the projector back together it won't turn on? what did I do wrong
thanks man! that was exactly my problem!
Ha! Thanks for the vid, man, but I just got a replacement for 50 bucks :D Buy "warehouse deals" in the amazon used section, they are just minor cosmetic imperfections.
Thank you so much….just got rid of my black stripes in the picture, thanks to your vid 🫵🔥
Got The same projektor says its going overheat. I thought all projektors had a dust filter cant find it here
Hi. My lamp is working but the Fan 3 is Not Running, the menu is saying that. Where I can buy the fan? Im from Germany.
mate thank you for that
not a problem
Thank you. Very helpful
You are welcome!
Wow thanks a million. Informative video. My w1070 lamp exceed life then lamp led flashing i took lamp out and switch on projector then fan stopped only red power lite on. Then i insert fused lamp again but still it has red power light and no fan. Is it lamp only issue or i have damaged projector. Haven tried fresh lamp yet. Please help.
And my old globe didn’t blow up just off.
Thank you!
Hi, i have exactly same exact problem and i followed it and now the Fan works fine. But unfortunately now the projector complaining about lamp (the lamp indicator goes red and shuts off after a min or so), this is original bulb which was working before i took it apart. I tried to remove and place the bulb again but it did not help. I think i assembled correctly, as the projector powers on, fan is running again.
any idea where it could have gone wrong? and which wiring should i check if it reports a bulb problem?
Tyvm for this great video and links.
My bulb exploded some days ago and i've yet replaced it. Thankfully, it seems all fans are working right (checked in page 2 of service menu, after pressing MENU,ENTER+SOURCE at projectors button panel). After two or three hours of use it seems everything's ok.
Anyway, as I've read that high operating temperatures could be the cause of lamp explosions I checked which temperature was the lamp operating at, and saw it's working around 280-300 degrees (F).
I tried to get info on the recommended or desired operating temp for the lamp but couldn't find anything.
Which range of temperature do your projectors are getting?
Do you think it would be a good thing the replace the fan while you're at it? I mean since your taking the thing apart. I was thinking about changing the fans for ultra quiet Noctua fans. I'm just not too sure about the required RPM and voltage of the fans.
Hey how can I do a quick fan fix? The bulb keeps overheating.
I moved my projector around after bulb exploded.I believe im going to need to do this. I really dont want to but i really dont want to buy a new one even more.
I would suspect so :)
The inlet fan connector detached from the circuit board during my disassembly. Can I repair by soldering or is it time to shop for a new projector?
I did this tutorial and now my projector doesn’t turn on wtf?
Did you figure this out ? Same thing just happened to me
Philip Watts nah lol I still have my broken projector in my closet someone told me it was cause I didn’t have all my screws in if that’s the case for you try putting the screws in the right place and tell me how it goes
The point is I’m gay def out my screws in correctly
Philip Watts yeah I’m not sure ever since it didn’t turn on after I repaired it I never touched it since it sucks cause I paid a lot for it
Dude your a light saver bought a new bulb and keep overheating. Found large glass in the fan.
Of course ppl order at the stupid terminals. You cannot order at the counter anymore. I disagree with all the customer upsides this video states. Ordering at the drive through is at least three times at fast.
Hey, great video. I had the bulb blow out and installed another one but it kept overheating. I followed your video and took out the fan and found a bunch of glass. I put it back together but now it won't power on at all. Any suggestions on what I may have forgotten to plug back in?
Hey - glad you like the video, and it's tough to tell why your unit isn't powering on at all. I'd first check if the new bulb is plugged all the way in? Also make sure the top lid is attached properly as it needs to push down a black button below it to trigger the power buttons to work.
Can you tell where is FAN2? I see FAN2 has errors
