Disassembly Xiaomi Mi Smart (youth) 1st edition projector
HTML-код
- Опубликовано: 7 сен 2024
- My HDMI jack was replaced in service for $30 in 24h. Assembly works well in reverse. Care must be taken with the front camera cable, which runs from front to back. I disconnected both ends before running it between the bottom two boards. Some pin-compatible HDMI jacks may be 0,5mm taller. This can work as a compromise, but you may need to file the back panel to compensate for the height difference. it is quite u polite of the manufacturer to give no documentation worldwide, not to mention spare parts, BUT given the quality and unrivaled power efficiency of these devices, we can only praise their modular design and straight forward disassembly.
Pe această cale doresc să ridic un falnic deget mijlociu pentru Service ESD București (singurul service Xiaomi din România) care la data postării acestui clip refuză reparația acestor aparate.

Please ..show us how to initialy open it
please
Yes please
...you just put a flat screwdriver or a cuttlery knife (a knife with a WIDE flat tip) between the edge of the white back panel and the body....and turn the knife´s tip a bit to pop the white back part off.
Once again, there´s no screws to undo. Just gentle turn of the knife at each side of the square back panel...and it will come off
Kind of a similar process he showed at 6:40 in this video to undo the front panel!
thank you for this video help me fix my Xiaomi projector. It was caused by a lose cable around the power button
my usb is dead, should i try to open it and get it repaired? or just use the projector without the usb functionality?
It is the same process as with the HDMI. Take the main board out then it is SMD replacement
@@mendebil replace the port? As charging works through that port but, USB connection to storage doesn't work
Great video, thanks for sharing. May i ask you, have you fixed or disassembled the power adapter for this projector? Thank you very much
No. But I hear mine buzzing when idle which is strange. 19v 3.5A probably most laptop chargers would be a good substitute
J'ai eu un souci avec mon videoprojecteur, il s'est coupé d'un coup et ensuite il n’à jamais redémarré. Pour solutionner ce problème j'ai démonté tout le projecteur, tout nettoyé au compresseur puis démonté les deux principales cartes électroniques (celle située tout en bas et celle se trouvant sous le bloc de la lampe) puis je les aient passées au four à 195°C pendant 6 minutes pour faire refondre toutes les soudures. J'ai ensuite tout remonté et ça fonctionnait à nouveau! Attention faut bien remettre le capot arrière pour que tout fonctionne, les masses des cartes électroniques sont faite par la tresse collée sur le capot 😊 j'espère que ça pourra aider quelqu'un. Bonne journée
PS: n'étant pas un réparateur professionnel je ne garantis pas que cela résoudra votre soucis mais il faut avoir en tête que démonter votre appareil peut être fatal en cas de fausse manipulation
Hey man thank you so much for making this video as there i no other on the entire internet for this model. My issue is i start having dead pixels I have many black and some white ones now aswell, everyday it gets worse. Do you know what kind of chip it has and if i could replace it? An answer from you would mean the world as i am slowly scared ill need to buy a new one :(
Hi. Sure my pleasure. It is really just a disassembly video so an engineer does not risk breaking it. For details tho I would have to check again, which is not really practical :) I hope you are lucky and find the parts you need
@@mendebil Thankyou so much for getting back to me! No problem don't worry, if you ever take it apart again it would be cool if you could share me a picture or serial nº of the DMD chip thats inside. Anyway your video is great on guidance on disasembly! Thank you again😇
@@jaktie123 Hi, I have issues with the same projektor (it only displays green screen). I took it apart following this video, and I went a bit further. I managed to take out the DMD chip. The part number is DLP3310FQM. I hope this helps.
@@zergonion I'm experiencing a problem with my projector - it's the second generation of the same model shown in a video. I'm noticing a lot of white and black dots appearing on the screen, which I've learned can cause damage to the DMD chip. I'm wondering how to identify the specific chip that needs to be replaced, and how did you manage to replace it by yourself?
@@zergoniondid you remove the screws from the module on the right that the video is at 11:32 there is a dmd chip with that part number or where it is located
Hello friend, can you help me? The flat cable of my retro broke, do you know which model and where I can find it on the internet for replacement ? My retro is the same model as the one in the video. Thank you
brother i need your help
I'm from Chile, but I'm going to translate so you understand me.
I have a project of the same model as the video, I had it for a year and one day the lens stopped projecting. (It turns on when it is turned on, but it does not project the image, in fact it lasts about 1 minute to turn it on and before it turns off it shows an image like green and black squares.)
You could help me identify if there is a solution and what could be wrong.
thank you very much for your help!!!!
@mendebil
Hi! How to clean a Black spot in mi smart compact projector? Thanks!
How to find DMD chip model in this projector? Is possible check this info in system settings? Thanks!
the lamp flash two times and then switched off, can you help me?
I have the same issue. Can't find no answer any where for this...
Same issue
Mine is 3 years now, it keeps shutting down randomly, I think it's overheating. I cleaned it with an air compressor but the problem persists. Anyone has a fix?
@@FranciscoMaiaPT they need a cool room below 30c also all sides should allow convection. There should be a warning for overheating and dimming of the picture. If you have no air conditioning in the house , forget it . Keep it off until September
@@mendebil hello , thank you for your reply. I have the projetor on my outside balcony and we use it only nights after dinner, when it's more cool. We are at the peak of summer here with > 35deg Celsius here, so it's really very hot. I believe it's overheating as you said, but what bothers me is that in previous years I had the same usage and conditions and the projector worked flawlessly. Moreso, I never get a warning of heating and/or dimmed screen. It works for 2 minutes, 10 minutes, it's random, it just shuts down in 2 seconds. I can just press the power button and start again...
Hi, I have the same model (bought pre owned) and the autofocus doesn't works anymore. It seems to try focusing (it makes the noise of engine rotating in the autofocus screen) but it's like if inside the mechanisms a "drive belt" or a gear is out of place😢. Shaking it makes no weird sounds. So basically the focus is fixed and can't be changed even after a factory reset. I contacted xiaomi but they can not accept to repair it for some reasons related to the warranty. Do you have any suggestions? I may try to ask help to some local repair shops in Italy but they probably never seen one of those projectors before and I'm willing to know if there are spare parts to buy somewhere. Thx a lot for your attention.
The AF servo motor has a gear wheel moving the lens back and forth. As simple as it can get. (You can see it at 11:30) if you know a CNC / 3d printer enthusiast (a person who builds 3d printers or cnc machines) it should be easy for him to take a look.
@@mendebilthank you very much for showing me the gear and the suggestions.
Hi, I already disassembled it almost 6 months ago because the fan makes a lot of noise. I found that the fan has some issue in the central pin. Do you know where I can buy the complete fan spare part?
I think you would be better off understanding the issue before buying anything. Is it the fan? Is it the driver?
@@mendebil it's the fan. I'm sure
I have the same one and recently it keeps displaying that the device is overheating. Any idea why? It's about 5 years now
Clean the fan. And keep it away from other surfaces. I keep mine upside down. On a piece of metal that acts as a heatsink
Hey, how do we open the back?
what is the led part number any please
Hey bro I ve the same projector, it’s gone all green. All the visuals are green. Can u help.
hy bro
i have same problim i fix it
@@muhammadsammar340 hey can u help me how to fix it please
Probablemente estén en el modo de imagen equivocado, hay 2 modos uno normal y otro, ponganlo en modo normal.
Imagen > brillo del proyector > cambiar a "modo visualización"
"Modo destacado" hace que todo se vea verde
Hello friend, I have the same model that you show in the video and today the equipment projects but with less light to a point that is decreasing so that no image is seen, only sound. I tried to contact Xiaomi to see if there is a repair center but I have no success in contacting them, what do you think is the reason? Will you have a solution if you take it to a repair center? Greetings from Mexico and thanks for the attention
Hola amigo. You need a good engineer who can disassemble it further. Sounds like a power supply or LED fault but I am not an expert
Hi all ! Any one face the problem that the speaker doesn't work sudden .... but ear jack and if I connect bluetooth speaker is fine ...
@@lamjeff1001 factory reset stock software works best
@@mendebil i have try to full reset thru the system setting... But still the same
Can u please help, mi projector stucks on mi logo
Yo tengo el mismo modelo me sale un aviso este equipo de esta sobrecalentado y su ventilador hace un sonido fuerte algo esta mal ??
Make sure it is well ventilated not In a confined space and you cannot place it upside down. You could also clean the dust if you suspect something
How do you open it at first Time? I don't find
any screw... I just want to clean the inside.
Take the back plate off with a plastic tool. Or a screwdriver
May I ask how to remove the back plate?
Mi projector solo prende en luz verde Green, sera que ya se quemo su foco😢, es el mismo modelo del tuyo
Did you managed to fix the issue ? I have the same :(
how to replace led light in this projector
You need to open the top module with the big heatsink and go from there
can you suggest suitable led bulb for this projector, thanks for reply
@@sri-lx4fi no . Needs disassembly hopefully the led.model is obvious. Surely some Osram chip
Dmd chip part number plz..
How did you initially open the plastic unit of the projector ?
The plastic back has clips you just need to be careful not to break them
@@mendebil so a sharp object needs to be used to pull out the plastic!!my projector is not switching on, so I need to check whether any dust has got accumulated
Opened and dusted, no luck !!
@@AshwinRaghavbunny check power adapter with voltmeter
@@mendebil sure!!
