- Today we showed you how to completely clean the LCD on your Yaber K2s projector, to remove those blackspots on your projector screen, which is dust particles on the internal LCD screen inside the projector.
we also showed you how you can limit future dust from entering the Yaber K2s machine, with some handy modifications.

Thank you for this insightful video. From past experience manufacturing HP scanners, I can say the glue used to bond the filter onto the projector may be causing the hard to clean haze you experienced. silicones are notorious for outgassing after use, and cyanoacrilates also cause issues as they cure. I don't know about hot melts, but it is possible this is a source of microscopic residue that ends up on the filter an/or lens.
Thank you for this awesome comment I would have never thought of this!
Any glues you recommend that doesn't cause this gassing or residue?
I think you may be right on this 🙂👍
A dust free environment is not achieved - only in a static free clean room.
Life is imperfect and the universe as a whole. Enjoy and embrace the flaws.
I found a 110 mm lens filter and 127 for about twice the price not bad I seen others when looking on google for over $100. So I’m glad I found one for cheaper than that
My one I installed onto this projector was only a £30 one shipped in from Germany that I found a seller on eBay.
But yeah these UV lens filters are far to expensive for a bit of glass, when I was searching I found ones for over £200 which is insane lol..
The ideal solution to this mod would of been to get a square peice of optical glass cut instead of a round UV Filter.
But I could only find square Nd filters around this size and not a clear bit of glass unfortunately.
Let me know how you get on with you new machine and if you suffer with any of my problems I had with this machine 🙂👍
@@ReviewingHub ok will do probably after Sunday I will
but a day time brightness comparison between the k1 and k2 could be a good next video if you needed any ideas or maybe not if it’s not much difference especially in the day time then nvm
I have a golf sim I’m working on in my backyard so I trying to see if 800 Ansi will be bright enough and I am attach a gray screen to my impact projector screen so I can use the project in the day time. My sim is under a tarp but still has lots of ambient light , I’m hoping that it will work but I’m thinking that the gray screen might not hold up.
@@ReviewingHub oh the 112 mm lens I found was $36 btw
@@thedayhayfilmsyeah any kind of daylight the K1 and k2 will probably not cut it, they recommend atleast 3000 to 4000 lumens for any day stuff under a gazebo or tarp personally I've never tried this but I don't think you will have a great experience in the day time with these machines.
Nighttime however they excel but daytime I doubt you will be happy with the light output and picture quality.
Let me know how you get on 🙂👍
It's Quite interesting to know what you planning 🙂👍
I wish I had the room to test both projectors for you.. But In such a tiny flat so it's not possible. 😔
@@ReviewingHub oh ok no worries yeah I’m hoping the gray sheet connected to the impact sheet works I just don’t know if I should glue it flat to the impact screen or if the Velcro will be good enough. I will let you know maybe I can some pictures of the results
This is the biggest problem with cheap projectors. I recommend using an air purifier in the room.
I agree 💯% they are great at reducing dust for sure 🙂👍
Galant effort, however these machines are not manufactured in a dust free envionment. You can do all you can to mitigate the problem but by design you will never eradicate dust particles . What i use and it is okay... woman's stockings. 10 derniers...jobs a good un👍👍👍
This is true, I've had many projectors with dust already in them from factory.
This method does work at reducing future dust issues,.
What are you using the stockings for? Part of the filter?
That would certainly help for filtering the air into the system 🙂👍
@@ReviewingHub quite literally place the filter in the stocking right into the toe. Then cut to size so don't stretch the stocking ,sew the ends.
That's a Great idea thanks for the info 🙂👍
@@ReviewingHub You're welcome,btw i took your advice and bought the Yaber Ace K1, i just can't face having to do what you did,the K1 has extra peace of mind with dust protection.
I think you will be very happy with the Yaber K1 it's an amazing machine. 🙂
Let me know how you get on with it 🙂👍
Seems odd that you wouldn't let the wipes dry and check its clarity before re-installing. Seems more strange though that Yaber seems not to have quality controlled the projector design before releasing it. As for the the filter, does it increase the heat generation inside? or fan noise?
Hi thanks for your comment, yeah I checked the lens plenty of times before gluing it on and it looked crystal clear to the naked eye..
Soon as light shines through it tho it's a whole different story ha ha..
I also found that the glue gives off gasses, so that's what's causing the fogging and misty filter once installed..
No the filter hasn't made any difference to heat management, and the noise of the fan didn't change in any way that I noticed.
Yeah the dust resistance on this K2 was quite bad on this machine compared to the K1 version.
Hopefully Yaber have solved most of these quality control issues by now, as the K2 machine has been out a while now.. 🙂👍
@@ReviewingHub As a glasses wearer, I never use a wipe myself on my lenses, they always seem clear at first but look terrible 15 minutes later. I use a waffle weave microfibre cloth that I use on my car glass, it's far superior, though it wouldn't be able to stop the glue off-gassing obviously. Thanks for the reply anyway 👍
I will look into the waffle weave cloths, thanks for the info 🙂👍
@@ReviewingHub There are two types. Waffle weave microfibre and diamond weave microfibre. I use the waffle weave to apply glass cleaning products and the diamond weave to remove it and polish the glass, though I suspect that either would do the job better than a standard microfibre. The diamond weave is silky, almost the same as the little cloth they give when you buy new spectacles. Gets my specs crystal clear every time 🙂
Hello.
I watched your entire video, and I found it very interesting because I have a projector just like yours, and I've had it for about a month. I have the projector mounted on the wall, positioned 2 meters away from a 2-meter projection screen. However, I'm not getting a screen size larger than 65 inches, no matter how much I adjust it. I've tried various settings, but I can't get it to cover the entire width of the screen.
On another note, I also have an issue with the sharpness adjustment, and I think it might be a flaw in the system itself. Let's see if they fix it in the upcoming updates.
Finally, I would like to know if it's worth buying a lens filter and if it will significantly improve the image quality. If it does, I would consider purchasing one, but I need you to tell me what type of filter would be suitable.
I've saved your video to my favorites in case I need to follow a tutorial to disassemble it and clean the dust. I appreciate your help and congratulate you on the video.
HI mate thanks for your comment do you have this projector the Yaber K2s?
If so the throw ratio on this projector is 1:54:1 meaning you need atleast 3 meters of distance to fill an 80inch screen and considerably more for larger projection.
In order to have a bigger screen providing the Projectors display is set at 100% screen size in the settings you would need to move the projector back further roughly 3 meters or more depending on what screen size your going for..
If you go to this website select your model of projector and it should give you a rough idea of how much space you need to fit your particular screen size.
www.projectorcentral.com/projection-calculator-pro.cfm
You could also try manually focussing the lens and turning off auto focus, as you may be able to get a sharper image by your own eyes by doing it yourself.
Also, large amounts of keystone correction can affect sharpness levels, ideally you want to use the least amount of keystone possible for the best possible image.
Also, with this UV lens modification this doesn't improve image clarity or picture just by adding the filter but overtime it can..
It mainly just keeps dust from being dragged into the projector when the lens is focussing..
And just generally being statically sucked into the projector when the projector being used overtime..
Because dust entering the LCD chamber causes black spots which is dust landing on the LCD screen.
With this modification it just reduces the dust from entering the machine which ultimately leads to a clearer picture for longer because you have less dust entering the machine.
Dust build up inside a projector is usually the main killer, so effectively this can prolong the life of the Projector too..
I Hope this helps you and it answers all your questions. 🙂👍
Hope
@@ReviewingHub Thank you very much for your answer.
Well, honestly I can't move the projector any further because I have it on the wall that separates my neighbor's house.
@vallisoletano34 I'm sure it should be set at 100% screen size already, from factory but you could check in the settings, then go down to projection, then across to projection settings, and scroll down to Zoom screen, click on this and see if it's set at 100% or been reduced.
If it's set at 100% then there's no other way to get a larger screen unless you move the projector back further unfortunately.
Hope this helps you 🙂👍
hi! I finally went for this projector. In general lines Im quite happu with it but the fan noise I find a bit annoying. Did you note a reduction in noise after changing the filter by the steel mesh? Looks like it would make the air flow quite easier... Thanks in advance
I can't say I noticed a diffence in fan noise mate, but I noticed a huge difference in dust reduction.
As the main filter itself is made of tiny little fibres and the fan sucks these fibres into the machine and lands on the LCD which causes black spots.
So just the filter modification is well worth doing.
If you put the projector on mode it does reduce the fan noise but it can take up to 30 seconds to 1 or 2 minutes to kick in.
But this also reduces the brightness level of the machine, so just keep this in mind 🙂
I'm glad your happy with it 🙂👍
Hello, I bought the Ace k1 model from Amazon. The biggest reason why I chose it was that it was dust-proof. But when I received it today, I can see one or two dust particles and black dots. Should I worry about this? Can it go away on its own? Apart from these, it is a great device! If you could give detailed information about it, I would appreciate it. I would be happy.
It most likely won't go away by itself, this is just dust stuck to the LCD inside the projector.
The only way to remove this is by cleaning the LCD with a cotton swab, or buying a hand-held rocket blower off Amazon or eBay.
I haven't had to clean the dust spots from the K1 yet, so I'm not sure where the door is on this machine.
But usually there is a sticker on the bottom of the projector. peel the sticker off the bottom and usually there's a little door you can open.
Open this door, and have the door facing the floor, and blast air into the projector! Hopefully the dust will be dislodged from the LCD screen and fall out the bottom of the projector.
If this doesn't work you will need to try the cotton swab method, or completely remove the LCD for cleaning.
But obviously this is more of a risk involved to this, than the other 2 methods.
Rocket blower method is your best option 🙂👍
Please don't blow into the projector with your mouth! As this will cause other issues. Because little pieces of your saliva will fly out your mouth and land on the LCD which will create water stains on the projected image.
@@ReviewingHubThank you for the answer!!🙏❤️ I think the model I use does not have an opening or screw under the label. I can give it to Amazon for replacement, but it is not certain that the new model will not have a dust problem. I am very undecided whether I will have the same problem if I choose a high quality model such as Epson or Benq. Because this I've read similar problems with models as well.
From my experience with dustpoof projectors, or the technical term manufactures use is an optically sealed engine.
I've had blackspots develop on all my optically sealed engine projectors.
Dust always finds a way into the machine eventually, usually when focussing the projector, or by the filtration system.
Hence the reason why I modify all mine now, to limit the dust issues.
But usually DLP projectors are far superior at handling dust issues, to LCD projectors.
So you may want to look at DLP projectors if dust is your main concern. 🙂👍
@@ReviewingHub Thank you very much for your answers. You helped me a lot. I will take what you said into consideration. Thank you very much again!🙏
wow! what wonderful work!! I just hope that RUclips will put the subtitles with translation because I don't understand :D
Where do you buy the lens?
I will type it all out later for you tonight, RUclips doesn't do a very good job, hopefully the CC subs will translate into your preferred language for you..
Please let me know, as I would love to know if the translation works 🙂👍
I brought the lens of eBay for 32 pounds, I can provide a link if you want it 🙂👍
Or you can try to find a cheaper one, but you will need a 105mm UV lens filter 🙂👍
@@ReviewingHub I didnt get--did you replace the original lens?
@@boombyte8849 No I just stuck a UV lens filter on the front of the projector, this is to stop dust being dragged in, and entering through the lens when your using the projector.
I also changed the filters in the back to better ones that stop the dust better.
And it doesn't have any blue tint this was due to my mobile phone most likely didn't have the correct white balance.
@@ReviewingHub I just use wet hand napkins as filters (just let them dry).
It's hard to judge the colors from the video reviews.
Hi.. Thank you for the video.. I have this projector and i have lenses full of dust and dirt on the corner of lenses.. I tried to clean the lenses from the little door under the projector but is impossibile to arrive on the corners.. How Can i clean all the corners of the lenses? Can i open the projector like you show us In the video and then estract the lenses? Is simple? Thanks
Hi, thanks for your comment. Is it black spots you are suffering from?
If so, this is usually dust on the LCD screen, which can be removed by cleaning the LCD screen, as I showed in the video.
Dust inside the lens shouldn't cause that much of a problem with image quality unless it's really bad.
To remove dust from the lens is a lot more complex, and I wouldn't advise taking all the optics apart.
If it's still under warranty, I would send it back if the lens inside is full of dust.
If it's just black spots showing on the image, it's just dust on the LCD, which can be solved by cleaning the LCD with a soft brush and then just giving the LCD a blow with a rocket blower (these are cheap on eBay), then just put the LCD back into the projector as quickly as possible to limit the amount of dust that lands back inside the projector.
If you take your time and follow my video, you should be okay. 🙂
Good luck and I hope this was helpful 🙂👍
@@ReviewingHub thanks.. I don't know if the dirt is in the lens or in the LCD screen.. I try to clean the LCD screen first. I hope it's enough. There is a little stain in the center and in the corner.. I tried to clean with the cotton fioc but is a dry dirt.. And it doesn't go away.
ho notato anche io il rilascio di pelucchi da parte del filtro , penso di aver risolto in modo artigianale disponendo uno strato di calza da donna sul lato del filtro che va in battuta verso l'interno della macchina.
Ha ha great stuff mate 🙂
Hey if it works it works ha ha 🤣
That's a great idea by the way, thanks for your comment 🙂👍
Ottimo, spero come hai fatto tu , di essere di aiuto 👍
why didnt you just put hotglue arround the original lens gap? instead of doing what you did with another lens?
Because the lens still has to move in and out for focussing, if you used hot glue in the gap it would glue the focus to a fixed position, so you will no longer be able to focus the lens.
Hope that helps 🙂👍
You may not need to do this modification as some are reporting they have no gap around the lens.
The filter modification I would suggest though 🙂👍
So I ordered this one and the k1 to see which one I want I also ordered some other Yaber ones to see the difference but for the k2s you recommend to immediately change the filter to the foam filter and then it shouldn’t have that space in between the lens and the body according to what people have told you? And if it does then just go with the k1? Is the k1 way less bright?
The foam filter and mesh mod that I installed in the back of the projector is far superior than the original filter yaber used.
I found the filter they used in the back of the projector was shedding little fibres and hairs and going onto the LCD screen which was causing more black spots..
Because of this nasty filter they used in the K2s projector.
It doesn't stop the gap in the lens.
Hence the reason why I installed a UV lens filter on the front of the projector, so dust can't get sucked into the optics causing even more black spots.
I do this Lens filter mod on all my machines as it stops dust in its tracks getting past the optics and causing blackspots.
By immediately putting a UV lens filter onto any projector you will then seal in the optics so the lens can focus in and out in a dust free environment without dust getting sucked into the machine when focussing..
If you watch my Wimius P62 video I explain more in that video..
The Yaber K1 is a far superior machine when it comes to dust resistance and overall build quality..
And during my review the Yaber K2s was on 100% percent brightness out the box making it appear brighter than the K1..
But after setting up the K1 again I checked what level that was set on and the K1 was only set at 50% brightness..
So there's no wonder why I thought the K2 was a much brighter machine.
To the average viewer I don't think you will even notice the 150 more ANSI lumens.
Hope this answers some of your questions 🙂👍
@@ReviewingHub ok cool that’s the best help I could ask for. I really appreciate your reply man I would have never thought to see if the brightness is lowered lol
@@thedayhayfilms Based on some reviewer testing the K1 is actually brighter and colourful compared to the K2s. The latter was actually a downgrade.
Hi,where did you purchase the mesh filter for the projector please ? 😊
need to invest in some cillit bang!🤣can't see them ever getting it right anytime soon
Hi! I just discovered your videos after recevingi my Ultimea Apollo P40 and searching across internet for the horrible electrical humming noise which I only found mentioned on your videos.
After watching your videos I am considering sending it back and getting the wimius p64, Yaber K1 or Yaber K2.
If I got it correctly, the better for its price is the Wimius, but which would you recommend over all three of them? I can only proyect across a 6m room though... So I guess the bigger the throw ratio the better but cant really find the info. Im liking a lot the sound and built in features of the K2 but also loved the better built quality you mentioned on the K1.
To sum up, HELP, which one would you recommend me of this three or this price range.
Anyway, thanks a lot for your great videos, your are the first channel I dont feel paid by any brand to sell their products
Thanks for your lovely comment my friend appreciate the support 🙂👍
They are all fantastic machines my friend, if you type in throw distance calculator on Google and go to the website and select K1 and K2 and choose your desired distance it will give you the biggest screen it will cast.
The K1 has far better build quality and dust resistance, it's just feels like a more premium machine than the K2.
If you already have a Bluetooth sound bar, or a good sound system and you already have a fire stick, Google Chrome cast, roku, or any other smart device you can connect to the HDMI port than I would say the K1 all day long.
The K1 is an exceptional machine for the money, that produces a magnificent picture.
If you don't have any of these things then the K2 has everything you could possible need in a projector, good sound, good functionally, and excellent performance.
But you may suffer a dust issue this is just from my own personal experience, the K1 doesn't have these problems.
The P64 is also an excellent machine, and has outstanding picture performance to price ratio.
But an issue you may not like with the P64 is you can only cast the picture onto the wall from 2 heights.
As there is only 2 feet on the bottom of the projector, so it can't be adjusted too multiple heights.
Unless you buy a separate mount or table projector stand then this is not an issue, and it's just another thing you need to buy.
It was an issue for me as I already have a screen on my wall in a fixed position, so I couldn't project the image were I needed it due to not having an adjustable foot.
If your casting just onto a plain wall then this isn't so much of an issue.
But it's worth noting.
Hope this helps 🙂👍
@@ReviewingHub And when it comes to lumens, is the difference between the K1 and the K2 noticeable? Thanks again!
I thought so in my initial review, However when I set back up the K1 I realised the brightness level was only 50% when on the K2 I realised the brightness level was On 100% from the factory.
So it would of appeared a lot brighter in my review. But honestly you wouldn't notice much difference from the two.
My plan is to get a proper light meter, and test the ANSI lumens of each projector I test. but good ones are quite expensive but that's the plan for the future 🙂👍
If ur watching movies or playing on ur ps5 is the dust clearly visible or is it just a personal preference thing if it bugs u?
Yeah it's clearly visible on light white backgrounds or dark backgrounds.
On white backgrounds it will show up as black spots, and on dark backgrounds it can show up as white spots.
It may not bug you and some people can ignore it.
Yaber might have sorted this quality control issue now I've pointed it out and you may get less of this happening.
But eventually all LCD projectors will get dust on the LCD eventually which will lead to black spots.
Even when they are suppose to be optically sealed, dust will find it's way in eventually.
The good news is Yaber engineered this projector really well, and you can easily remove the LCD and clean it with a soft brush.
Just undo the screews on the bottom, and pull of the lid, and remove a few plugs, 1 screw, and undo the ribbon cable, and slide the LCD out.
It's really easy to do and doesn't take long about 15 mins max, so when it gets really bad and the black spots bug you, just give it a clean.
Some projectors are not as simple to remove the LCD so this isn't always an option to some people if they are not DIY minded.
Thankfully this projector is great for cleaning.
I've shown how to do this in my video so just follow along when it's time. 🙂👍
You may not need to do this though for many years.
Some projectors are better than others as dust resistance, at the time of my review this machine was pretty bad for dust.
But hopefully Yaber have made things better with this machine by now, they are a great company and for customer support. so if you have any problems just reach out to them. 🙂
Hi,
But in my one it is sealed no gap
That's Awesome! Thank you for commenting and letting me know this 🙂👍
So this projector is not worth it?
No it is worth it, it's a great machine! Mine just had some issues, hopefully Yaber have sorted the dust by now with this model.
Thier K1 was excellent with dust resistance, and I highly rate that machine. 🙂👍
