Two things: 1) In this video I show checking the fuse to be sure there is no voltage there. As several commentors have pointed out (Thank you!). This is NOT the correct way to check voltage on the large caps. You need to check on the capacitor legs themselves. 2) Just wanted to add that with items like these I either test them more extensively or I sell them as untested. Either way I always make sure potential buyers know what they're getting. I'll be posting on my community tab, Instagram an Facebook when I start selling stuff.

Even if you test them, you’ve openly admitted that you don’t know anything about projectors. These aren’t like consoles or TVs. There’s far more to them than just turning on and displaying an image. Without an actual projection screen, you won’t even be able to properly test them. I applaud you for branching out on what you “fix” but you should at least have some knowledge of what you are working on. This just seems like you’re greedily buying up random, cheap stuff on eBay in order to make videos and quick sales for profit after some tinkering and cleaning.

Glad you mention 'cause I was already wondering how one can call a projector "all fixed" when not even a stand-still image on a proper projection surface was tried. In case you decide to do the testing, I'd be interested in a video on testing procedures and outcomes for sure... Oh yeah, and testing the voltage drop on a fuse doesn't seem to make any sense.. I was wondering about that, too.

@TerminatorJuice 2 года назад
As a home theater projector owner since 2005, I can tell you that just having light output does NOT equate to being "fixed". You need to test with the image projected on a wall to make sure you can get it focused and that the colors and contrast are acceptable with moving images. You can have an older bulb that puts out light, but the image will lack any depth or looked washed out, so that's something that needed to be tested.

One small notice, when checking if there is charge in capacitors, always measeure voltagr across storage caps. Measuring voltage at socket will always show 0V (if bridge rectifier is good) because bridge rectifier will block DC. Also if fuse is not blown there will not be any voltage across it. (There will be voltage drop across it when the projector is drawing current while its working) This time you get lucky that storage cap have bleeder resistor. If that is not the case (as it is for many chinese PSU) you could get high voltage for days at that capacitor and your methods will not detect it. So ALWAYS measure voltage at the big caps. If there is residual charge, use high wattage resistor, 1K or lower to discharge capacitor safetly.

Test them like at least 1~2hours . When I worked on projectors cost over 10,000 dollar per each. They sometimes showed some sort of weird issues when I run them for few hours. They were expensive but not reliable at all. *Rumors and things I experienced, If you use "non-genuine" lamp for your projector, they might cause damage to a filter on lens which might give you fuzzy or darkened image even after putting a new lamp. (We ended up replacing several projectors due to darkened image Replacing a lamp was not a solution)

Awesome man! One thing though, never, ever , ever clean a lens with alcohol. The alcohol can very quickly damage lens coatings, specifically the anti-reflective coating that is on them.

@@dorfschmidt4833 I can understand why you may think that is wrong. A cursory search on Google gives you an answer to clean anti-reflective coatings with a 15% IPA 85% H2O mixture, directly from a coatings company. What that search fails to explain is that to REMOVE anti-reflective coatings you use a 85% IPA to 15% salt H2O mixture. The salt merely helps to oxidize the coating faster to remove it. Considering that we in the electronics repair community use 99% IPA most of the time, it is absolutely not recommended to use IPA, even 70% IPA on coated lenses. Sure, if there is no coating, use as much alcohol as you want. I have used all techniques to clean and/or remove coatings. Years ago I would ALWAYS use alcohol to clean lenses and I always hated when coating would start to degrade over time. My thought was that it was just wear and tear. then I learned about all this crap and low and behold, no more degraded coatings.

It's hard to know what testing to include in these types of videos. Usually the more testing I do on camera the less of the video people watch so I usually minimize the testing I show. I agree that if I were to sell these as used and tested then I would need to test them much more extensively. Anytime I don't have time to test something fully I sell it as untested so the buyer knows what to expect.

Most of them had dust in their optical part because the filter had crumbled because of bad material, some had thermal cutoff fuses blown and some sony ones had a faulty chip on power supply. Anyways, its important to check the image, that its not dull, because of something in optics, like dust or that the colors are not off, sometimes there is something wrong with the LCD-s.

You had one screw that fell out in the one projector that had never been opened. That sometimes happens when they are mounted to a drop ceiling that has airflow above it. It causes a vibration in the projector that you can actually see. After years of vibration the screws can loosen or fall out. I work in a school district and we deal with this sort of thing fairly often. Great video!

Then group the ones with similar faults together and work on the biggest group first. Also, always label every single part you remove so you can trace it back to the unit it came from.

have a look on the color wheel (only to find in DLP projectors) somtimes the ball-bearing dies and this could be the buzzing noise i had such a problem in my acer projector it sits right between the lamp and the very beginning of the light tunnel and for the lamps you cant really tell if a lamp is good or not by looking at it the lamp driver board has a complex voltage and current parameter program and it will monitoring voltage and current used by the lamp during start up this kind of lamps need low current at the beginning to warm up savely but the voltage and current is getting up after a while and then it gets brighter but after a while the lamp will have a constant current mode but the voltage can stil vary if the lamp is getting older the normal voltage rises and if its out of spec you will get a lamp error keep in mind the logic of this board can only measure it when the lamp is in full power mode (warmed up) that means if you have a bad lamp it will kick of at the very end of the warming phase or even after hours of being on due to rising voltage this is caused because the arc in the lamp needs more voltage to stay stable due to rising preasure inside the bulb by vaporising metal

Those speckles on the image are not from dust on the lens, that's the DLP chip that is starting to fail. The easy way to tell is to adjust the focus, if the speckles rotate then it's dust, if they are stationary it's the DLP chip. You will find pixels both stuck on and off, basically that projector is trash. I wouldn't be surprised if the rest also suffer from that issue as they are all DLP and Optoma brand are know to use the low grade chips.

One has a fan noise. 3 have broken light reflectors (fixed with bulbs from dead units). 2 have have the metal nubs on the buttons broken off (fixed with built up crazy glue on the plastic of the button). Some have broken case plastic. Our instructors wanted bright and high resolution so we got 4000lumen 1920x1200 units. We need a more rugged replacement.

Man, these fixes are kind of half assed like others have said. These should have been hooked up to inputs after the repairs and run for at least the length of a two hour movie each. Then run a video game on each for another hour. At that point, if everything checks out heat and smell wise (besides picture, color, brightness), then you can feel pretty comfortable they are fixed. I have owned Optomas multiple times. And sometimes they run fine for an hour or so. Then quit. Things like bad colorwheels. Bulbs that dim after they heat up, ect.. Optoma is not a real dependable brand quailty check wise IMO.

I have a similar projector as at 12:50 (#3). I remember having lines show up on my screen because mine was a refurb unit, and so I noticed that they only showed up when I ceiling mounted it. So naturally, I squeezed it! This was to countact the tension of ceiling mounting it and it fixed it! Now I know it was probably a loose connection on that board with the missing screw you had.

After 14 years making a living repairing mainly audio amplifiers I bought a new £3,500 Dell S718QL UST laser projector for the college where I work in 2018. While soak-testing it I noticed a faint yellow staining on about 20% of the middle of the image on the white test mode (you can get it to project various single colour rectangles). Subtle but faulty and not a dirty lens. After a long phone call to one of Dell's engineers in Scotland they accepted it was faulty and replaced it. Most people wouldn't have noticed the problem in a college, although a home-cinema owner might have.

I bought a high end 4k beamer once and had issues with it from the beginning. It just turned off after a while for no obvious reason. Leaving it on for 5min was not a good test to see if it actually works. I would test for several hours with video signal going in, as this is what it is supposed to do.

I've worked with theater projectors for over 20 years, cleaning a lens with isopropyl alcohol is not recommended from my experience. It leaves many streaks and can be a pain to get completely streak free. My suggestion is a little distilled water with your cotton swabs.

@marcusdamberger
@marcusdamberger 2 года назад
That's the problem with older projectors from just a few years ago, they may have some comon fix thats easy to do. But then the tech moves so fast, the value of them plumets because the current gen is so much better quality. I mean who wants a projector that has a native resolution of 1024x768 XGA resolution with 4:3 aspect ratio? You see a ton of used ones like that on eBay, sure they are bright 3200 lumens, but their contrast ratio is horrible.. What is awful on eBay are the cheap Chinese no name brand projectors claiming ridiculous specs for cheap. Stick with name brands like Optoma, Epson, BenQ, Sony, JVC etc. Avoid those Chinese knockoffs like the plague, I've opened them up, hot glue holding down wires, plastic lenses, single speed fan, (for a time, crazy hot quartz light) single LED bulb like those used in drop work lights for shop work.. same control input board used across every cheap Chinese projector thats 1/4 the size of control board you see here. That can accept up to 1080p resolution input that gets converted down to LCD panel resolution that is SD resolution (480) that has crappy contrast. And everything is plastic inside, all subject to that heat the LED high output light puts out. Its slightly better than the old quartz light they used to use, but still tons of heat. Nevermind the fan noise is so much more than on a name brand projector. They just pump these projectors out by the ton, and they end up in our landfills within a year or two because the LCD panel gets burned from the heat. All pure junk. Just buy a name brand projector thats used and it will last years and be far superior in picture quality for the same price. And those $100 projectors listed have almost no brightness to them. More than useless if there is any ambient light in the room.

I've been watching your vids for about a year now and enjoy them all. You dropped the ball on this one. I know you do more testing but you can't call something fixed if you only fixed one part of it and not the main part of what it does, project an moving image not just light. You should have hooked up at least a console to them to see if they can receive and transmit a signal. I'm not talking about all the things that can be wrong like blurry image but just a image in general.

@Tronicsfix
@Tronicsfix 2 года назад
There are very large capacitors on this power supply. Capacitors store a charge for (usually) a short amount of time even when you unplug the power cord. This large fuse is on the main power line and connected to the capacitors. If there was a charge in the capacitors there would be voltage on this fuse. Since there was no voltage that told me that there was no charge in the capacitors and that the power supply was safe to work on. EDIT: As several commentors have pointed out my method for testing the voltage in those large caps is wrong. They need to be tested right on the legs or the capacitors themselves.

I've skipped the buy the broken ones and went straight to the office upgrade auctions. Bought 6 projectors for $200 and they worked. Bought a dozen monitors for about $10 for each. Sold them locally on Craigslist, but kept the best monitor and projector for myself. Be sure to go into the projector menu and pull up the lamp hours. Helps to sell them if they have low hours on the bulb.

To explain the smoke, any projector (the light bulb specifically) runs incredibly hot and essentially you are seeing burned up dust. Something worth cleaning for sure, but definitely normal for any projector. I repair and maintain medical equipment which includes projectors for Optometrists.

Worth mentioning these bulbs run turbo hot and you're meant to leave the projector powered and in standby at least until the fans turn off, otherwise the bulbs can melt themselves with the leftover heat and that's not repairable for any reasonable cost. Gotta replace them then.

Great Job Sir. Zeiss makes an optical cleaner, for outdoor optics, binoculars, things like that. Nikon also makes something called a "lenspen" that cleans lenses on optics.... Zeiss & many others make Lens Wipe products also, which come in a little single use package, and when you tear it open, a very clean wet tissue is in there, safe for coated optics.... I would invest in all of those, if you are going to mess around with stuff like this. You'd hate to ruin the coatings on a lens, and basically torpedo any value the projector might have.... There is another product, looks like a fancy bigger q-tip... the ones I have are sold as "Extreme lashes Lint Free Applicators"... Looks like a fancy Q tip. I'm not sure what sort of black magic is involved with these, but they pull dust & offending dirt off of a lens like magic. Like weird magnetism. Really neat product that I found doing watch repair. Theoretically, those mirrors in the bulb area should be pristinely clean also.
