I love these cheap projectors. You can put them outside and not worry to much about them during the holidays.
Thank you! I received a unit with dust already in the lens. They are sending me a replacement and I can keep my old one. Figure when the new one comes in I can take it apart and see if I can clean it off. Now I’m the only one that noticed the dust on the lens after watching a movie with a bunch of people.
Your power board is a boost converter. It looks like your projector is powered from a wall brick or an inverter somewhere external to the housing, based on the barrel jack. The low gauge wires have to carry high current from the DC-in jack to the boost board which likely steps up that voltage to something a little higher for the LED array. The other 5-pin connector between the boost board and control board must get instructions to adjust voltage on the LED power rail based on brightness adjustments from the I/O board or IR remote input. Maybe there's some pulse width modulation going on on the control board, possibly feedback from the boost converter. One of those 5 pins must be a switch to turn off the boost converter (and therefore the LED) entirely. Thank you for the video!
Amazing..... it's like the Overhead Projector/Laptop screen combo idea I saw tinkerers making years ago. Nice to see idea made into a product! I guess that's why we won't see this tec in tiny projectors - that amount of light on an inch square LCD would melt it...
This video helped me lot to clean my projector. Thanks

Thank You

Mine broke because I touched it after getting up from the couch (static) but everything still works, it was a smaller one with no keystone and it was a smart projector that runs all the current video apps.
Since I couldn't find any replacement LED or any accurate information about it AND it's possible that some micro component is causing it to not have power, I have decided to rebuild it on a box myself, with a powerful LED garden spotlight AND I will add keystone adjust since mine didn't have one.
Also, mine was designed for smaller rooms, that's why I had to have it on a tripod awkwardly in the way so that it fit on my wall, in order to fix this I will probably remove the mirror and flip the LCD panel around.
If it works it works.
damn, an LED spotlight?! thats gonna burn ur eyes
@@c.e.ooftaxdeduction So be it
Thank you for the video 👍
Modify using display LCD x 2 panels in two layers. To make the color dark and add LED watts.
I'm wondering if anyone's tried upgrading the LED/driver for one of these? Not a bad cheap little guy if it were brighter.
Not only the led/driver but also the lcd for higher resolution
Let me know if you have tried to swap it
My cheapo one is 19v. Seems easy to swap led. But the chips I found use higher volts. Separate driver perhaps. The power simply goes to a rely which turns on the driver maybe.
I would have sprayed the interior plastic of the "light engine" path flat black while I had that thing apart and all the components out of it. Should help with the spill on the screen. and maybe upgrade the LED...
Is the fan a standard connector like a pc fan and can it be replaced. From what I can see in the video it doesnt look soldered to the board. Right? Thanks.
Can you tell me which two screwdrivers you used? Thanks, great video.
nice video, let us know about that how to dismantlement of TFT LCD (android mobile) for projector building. thanks.....
Can you replace the lcd lens from 480p to 1080p
where can i get the small power board with the coil i have a simular model projector but 2 capacitors have swollen and burnt out.
Man, I wish I saw this before I took mine apart. Mine is a Bigasuo from Amazon, and it has a low res dvd player that I hardly use. It’s mainly for my fire stick and other hdmi stuff. but the thing is nice and bright. It runs day an night. But it’s been dusty for almost 2 years. I finally tore it down to the black hub hat covers the screens, mirror, lense.. well I think I may have cracked my lcd screen.. as I did not know that’s what it was.. So, can I replace that part? It’s practically the same inside design as this, with a few exceptions, just mine has a dvd player.
What was the size of the lcd?
This projector gets the job done pretty well. ruclips.net/user/postUgkxS9P8zTOcmQg-hH0QeUi3dspOLyYgQ6dH Bear in mind it's a mini projector but all things considered the picture quality is pretty good. The attached photo is of the projector projecting onto my white closet doors. I still have not messed with the settings but I can't wait for our first family movie night on a larger scale. If you have issues with volume not working with your firestick, go into volume settings and you will find your solution there.
Thank u!! =)
Does anyone know how to put the lens back together? Got an OCD disabled guy living with us who bought one of these and saw a teeny lint hair so tore the whole thing apart. Never even got to use it and he already wasted $70 on it.
My cheap projector had a power surge and went dark. Rebooted and now theres a big brown spot right in the middle.
I have a problem, my projector fall down, and now the light looks life if were a lighting, circle light🔦
Took mine apart to clean the lense and the lense fell apart and i carnt find any pictires of a exploded lense to rebuild the lense completly has the lense fell apart and ive no idea in which order the lense parts go back together im so frustrated at my top vision projector now and ive tried lots of ways ie lots of diff orders for the lense and i still not getting a picture so im going to throw the hole unot im the bin
Mine doesnt have the white cords with circuit board. Should I be worried?
I have this exact same kind (part) of projector, is it possible to replace the LED to a higher power to increase brightness ?
No
Disassembled the entire thing except for the part I was watching for. THE LENS! I can't figure out the correct order.
Is that a normal mirror or does it have any specific name/tech to call, In my projector that mirror has broken.
Where can I find replacement parts ?
Took mine apart my self and put it back together. But the 3 piece lenses and the retainer are really hard to put back in the right order. The struggle is real
I’m having the same problem do you remember the order?
I opened mine and now when I turn it on I just get a flash and it turns off 🤦🏽♂️
RIGHT...
where to buy a new polarizing lens? Mine was getting a brown spot area on screen. I have had it apart and discoloring is indeed on polarizing lens (or can it be cleaned and with what?)
did you find where to find polarized glas
My question is HOW do I get replacement parts? I can't seem to find ANYTHING
You buy a new one. They are only 50 dollars
@@mr.hankie not wesr I live shipping cost alone is double the price.
How many inches is the lcd panel? I'm trying to order a 1080p panel and put it in there?Or maybe put a smartphone full-hd parts inside.
I doubt that would work... the circuitry that drives the panel would have to support output at that resolution, and I doubt it does. That and the pinout of a 1080p panel would likely be different. It would be much easier to just get something like the Vankyo V600 from Walmart... native 1080p, and $200.
Really interesting seeing what is inside these cheapies. Where is the review of the projector mentioned?
I suppose I should link to that in the description... in the meantime, here it is:
ruclips.net/video/-V6Hzx2ckhY/видео.html
mine was unplug for a couple hours now and i just tried opening one of the screws and some white powder came out onto my screwdriver and when i went to touch it (wich i shouldnt have) the powder was REALLY REALLY HOT. someone tell me what to do
My mirror broke. Do you know the size or where I can get a replacement??
Same thing happened to me, did you find a replacement?
Does anyone know if you could replace the LCD panel with a 4k one and how the resolution would be effected after you do that? If think it would work but I'm not sure if the other components would use the full potential of the 4k lcd?
Haha... no. Even if they did make a 4k imager that size, it would have a different pinout. Even if it had the same pinout you would need an HDMI board capable of driving a 4k display. Even if you had an HDMI board capable of driving a 4k display, the lens is so poor that the image would not be in focus enough to resolve 4k. The focus isn't even good enough to show a uniform image at its low native resolution.
@@FamilyHomeTheater They do have 4k screens small like that, I've seen videos of people make 4k projectors using them. I was just wondering about about using this as a base because it would be easier, probably have to switch out all the electronics but everything else is there and should work.
@@FamilyHomeTheater what about a true 1080p LCD? I know for a fact the output is 480p on the Goodmans branded version of this same projector would be amazing to watch blu-ray movies with this without the image being shrunk down to DVD quality
Mine started overheating and creating a big black dot in the middle. Soo to find out I had the fan backwards so hopefully that will fix it🙏🏻
My projectors doing the same thing. once I leave it on for about a minute a big black dot appears on the screen. Were u able to find the problem
Mine projector luminance is not bright
Hi, I attempted to clean the inside of my projector. This is my second attempt of doing it but now I'm getting a white screen? Help please!
Probably the polarizer is reversed. Flip it around and it should work.
mine led projector is getting dim. what should I do?
Not a professional but mabey replace the LED or the driver??
how to change the Lens tks
I took apart my projecter once and it stop turning on
Neat
Can u do a lense teardown ie a complete teardown and rebuild for a topvision projector that would help me out
Sorry, I don't have this one any more. I only have the projector I use. Assembling a lens from elements probably takes special tools to make sure each piece is optically aligned, and it is not something I've ever done before.
Quand j'ai vu le démontage me suis dit soit c'est un pro soit il va le regretter moi même j'ai inversé les verres et pourtant j'ai tout pris en photo il m'a fallu plusieurs essais un vrai casse-tête pour retrouver la bonne configuration maintenant j'ai installé des repères et le dernier nettoyage c'est passé sans soucis
My project dropped. I can't figure out the lens assembly. Can you show how the lens go together
Sorry, I don't have it any more. It went to my kids who weren't gentle with it and they finally put it in the garbage it a week or two ago.
mini projectorssThe projector says it’s output is 720p, how can I get it to project in 1080p as described? Thanks!
This projector can't output that resolution. It will accept the resolution as a signal source, and will down-res it and display it at it's native panel resolution.
10 views already, only 99,999,990 to go!
Our projector fell and the mechanism that you can externally adjust the focus with broke free from the glass piece it controlled internally. I got the mechanism put back together and the focus worked again. But now the bulb is turning off every 30 mins. Any idea what would cause that? TIA
Maybe overheating? The heat sink may have gotten jarred loose.
Check ur option settings maybe you hit sleep timer
My projector just started having vertical lines. What is the most common issue in your experience ?
Maybe a loose ribbon cable or connection to the LCD element. If not that, probably the video chip has gone out.
Wish you would've took the lens apart. Having problems with putting mine back together and making it focus
Me too
Me to
Do you know where I could get a replacement power cord?
If you know the voltage and polarity, Amazon sells universal DC power supplies.
You didn't take apart the lenses😔
if you removed the keystone plane would the projector seem sharper and brighter? wondering if you had any thoughts on that?
Maybe... unless it affects focus somehow. For $70, its worth a try.
It affects focus, don't do it. Ask me how i know that ahahahaha :)
5:00 ??? The name of this component please 😉✌️
Lcd type ips
I took apart the projector and followed your every move but putting it back together something went wrong...... The screen won't show the logo or video it's just white. Can u please help. By the way not your fault. I just did something wrong
did you put back the lcd screen?
Check the connections of the ribbon cable going from board to lcd, did you take it off, did younput one end in backwards?
The polarizing screen might not work backwards
Was really hoping to get a better look at the fan, or better yet a part number for it so I could look for a quieter one and see about giving it an upgrade.

cowboy /.a think this is that and thats for this lol and couldnt see a thing
