Hi everyone, I have a Xiaomi Mi 4K Laser Projector 150" and I'm experiencing an issue where the projector only displays one color after a short time of use. When I first turn it on, the image appears normal with all colors working correctly. However, after a few minutes, the screen shifts to displaying only a single color (e.g., red, green, or blue) and the other colors disappear. Has anyone else experienced this issue? What could be causing it? I suspect it might be related to overheating, a failing laser, or some issue with the power supply. I'm not sure if this could be a hardware problem with one of the lasers or perhaps a cooling issue. Any advice on how to diagnose and fix this would be greatly appreciated. Thanks in advance!
I have an old white xiami one and always have the auto turn off issues. And now it just say the fan is not working and turn off automatically, would this be the same issue? Sorry to take your time. Thanks a lot 🙏🏼🙏🏼🙏🏼

got a dead pixel on my Hisense ultra short throw projector lately. lucky the warranty expire next month. A technician supposed to come today but had to reschedule because he said he have never work on one before. I hope i on't see him watching your tutorial to fix my device next week...
ViewSonic makes ok Projectors, but their operating OS systems are terrible. !!!!!So basic, you have to put a firestick in the back of their projectors. (It's hell trying to get their basic operating systems to play RU-vid and lots more basic apps that should be pre-loaded, but they're not !!!!!.) OK, this is solved by putting an Amazon fire stick in the back of the Viewsonic m2 projector. Then we come to the sound, OMG. I have heard better/louder sound on my mobile phone, there is no Base at all even with the sound adjusted to its maximum base !!!!! They say Harmon Kardon speakers are built-in. HAHAHA, how disappointed you will be. Then the Keystone correction has a massive bright border shadow !!!!! that is so distracting !!!!! (that's when the keystone works properly). good points !!!! good picture in a dark room/ and the projector looks good and runs quiet. (would I buy it again !!!! no way there are much better projectors out there for the same amount of money).
I have A300 projectors having the same problem. Your video is a great help to know, i am not savy to do the repair myself. Is anyone in Singapore able to repair for a fee?
Hi i’ve the fengmi 4k 2021, everything was fine for the last 3 years and today i wanted to change de fastfocus after months without no settings change and i discovered the fastfocus is « broken » it’s not working anymore and the top part of my screen est full blur 😢 do you have any idea what i can do? Best regards and thanks for your help 🙏
Hi Nikos, first of all great work. I very rarely write a comment, but I just had to write one.... YOU ARE AWESOME. Now to my question, are you selling the metal part? I haven't found it anywhere. My projector is now making these white lines. Hope you can help.
Thank you for this video. Great example of the difference between this ALR and standard screen and how well it copes with light at the edges of the projection - no need for a boarder. This is perfect for me because i have inhertied a 16:10 projector and one day will upgrade to 16:9, so I won't have to change this screen. Perfect. I think i may have found the screen for me.
J'étais curieux puisque j'ai complétement modifié mon vidéoprojecteur led je peux tout réparer ou changer dessus zero obsolescence, mais le laser c'est d'une autre planète
I never add any comment on youtube but i want to thank you for this tutorial ! I just repaired my xiaomiprojector having troubles for the last 8 months thanks to your perfect video. Have a nice day and once more thanks !
This was 1st used in the 18 hundreds film was found. And people did not see it. It was 3 frame each was taken with a colour fly wheel. Projected with a coloured fly wheal was BW film.
Thanks for the review, that is what a test should look like, not a lot of talking and a lot of test on and off the screen to see how it reacts! EXCELELNT job!!!!
Urgent answer needed!!!!!!! Can you use any brand Wi-Fi/Bluetooth dongle with this projector. I've misplaced mine and ordered a TP Link one but not sure whether it will work? Also finding it hard to source spare parts in the UK
Hello @nikos do you know any place where we can purchase parts of this projector, i am not having this issue but having issue with color, there is green/purple tint in some scenes with bright light, maybe because of faulty optical engine.
hi, for the me only teh HDMI ports of the projector is not working. Have you come across this issue before? the projector works fine, but the HMDI ports does not detect the input device. Can you help me with a solution?
Awesome! Your video really help me understanding my content. I had a 720p projector DLP however later I change to 4K DLP, I was not satisfied the edges and sharpens from the 4k DLP. Now I understand why so. Feel like these guys cheated me by selling a stupid technology for a higher price. Can I ask one question, if the manufacture claim native 4k support in their projector, do they actually have 4k resolution or are they trying to cheat again with XPR module. Please advise. Thanks.
Holy waste of time. Get to the point, we don't need 10 minutes of B-roll with 2 minutes of content. No one cares about you unlocking your door or your cat. Thumbs down.
