LED Projector Repair?

[@bootsowen]

This sums up the vast majority of things that I repair, something small and another factor. The other factor is usually that the previous owner didn't like or had grown tired of the item. The vast majority of appliances are thrown out because of something trivial, e.g. blocked pump and are also dated or have rust or some superficial damage. It's a great hobby.

[@BuyitFixit]

I think it was cash converters that were selling this. I guess they aren't that technical. Thanks bootsowen 👍👍👍

[@BuyitFixit]

Nice one Rob👍yes people here often do the same but it's usually things like TV's with busted screens, or vacuum cleaner etc. I've not really came across that much interesting stuff...

[@Mymatevince]

I enjoyed that Mick, nice bit of fault finding to narrow down the issue 👌👍👍

[@BuyitFixit]

Hah. You're a proper night owl! 😂😂 I've just finished editing and started uploading a couple of new videos... Thanks Vince 👍👍

[@Mymatevince]

@@BuyitFixit 😂 Always have been! Never been early to bed BUT neither am I early to rise!!!

[@BuyitFixit]

@@Mymatevince Pity about your Dyson fan. Great effort though Vince! 👍👍 and thanks again for the mention. Got a switch mode power supply repair for the next video. I give a rough explanation of how it works. Proper repair that one.

[@Mymatevince]

@@BuyitFixit I've ordered another one!!!! Maybe the 2 can be combined if the fault isn't the MCU. Look forward to your next vid👍👍

[@BuyitFixit]

Nice. I hope you get it sorted. If theres anything you need a hand with or if I can help in any way just give me a shout. You can always drop me an email too at [e-mail]

[@jimjones1652]

Same thing happend to me. I won an auction for a small amplifier sold as faulty, cutting out when volume increased. Looked at the requirements and it needed 12v at 2amp and the psu was rated at 12v ,0.5amp. £1 incuding delivery was one of my better wins.

[@BuyitFixit]

Nice one Jim👍and well done for spotting what the 'fault' was 🙂

[@specialservicesequipment393]

JRC had once made a MF/HF radio with an underrated capacitor in the power amplifier section. It was supposed to be 50vdc and it was rated at 25v. We had to butt splice in the proper capacitor and clip out all the 25v ones that were already installed on sea going vessels.

[@BuyitFixit]

Hopefully they weren't moving at the time. I get awfully sea sick 🤮😂😂😂😂

[@MrEwool]

Very small, and aparrently not very good projector, might be usable for those old 8 bit games, but nice little fix. Appreciate all the work you put into making all this content for us

[@BuyitFixit]

No problem. I've been hard at work the last few days making more video's. Got a nice switch mode power supply repair coming next...

[@BlondieHappyGuy]

Actually, I was surprised as the very low res on that thing. After all, it has an HDMI port on it, which seems overkill for that res. Since it appears to also take an SD card (I think) it might be cute to make some kind of holiday mini videos and shine it on a window for passersby to see.

[@BuyitFixit]

Thanks Blondie, yes it's resolution is very poor by today's standards. Yes a small holiday player would be good, apart from we are very remote and our nearest neighbours are about 1/4 mile away so I guess no one would see it. Where we used to live I built a xmas light show with RGB addressable pixels and syncronised it all to music. There's a few videos on the channel if you scroll back far enough!

[@BlondieHappyGuy]

In cases where the power adapter is the correct voltage/amperage, I don't know about others, but the very first thing I do is to check the voltage of the adapter and if the voltage is correct, then I do a load test on the adapter. Many times, an adapter will fail to where, without load, the voltage is correct, but as soon as there's a load, it drops right off. I have this issue now and then with our security cameras. Some are outside and when one stops working, it's always been the adapter giving up the ghost. Using a test adapter always confirms this. Fortunately, these adapters are easy to fix.

Several years ago, i bought a projector from a "surplus outlet" kind of place for $5, didn't work (marked as such) got it home, opened it up, and literally 1 skid mark on the PCB, tiny sot23 n-channel fet... took me all of 11 minutes to replace it, and the projector works perfect to this day.

[@BuyitFixit]

Nice 👍I've had a couple of items where it's just been one tiny component. The SSD I repaired was one that springs to mind with just 1 shorted SMD cap.

[@elsaarmstrong-zp6ng]

I still have a old slide 35mm projector and dozens of family pictures which I intend to get on print! I have to power it up with a variance as the halogen bulb tends to blow up if switched straight off the mains . You can’t get the bulbs nowadays apart from eBay which is risky! There is a camera shop not to far away who will do prints chemically but it ain’t cheap! I could get them scanned on to jpeg but I have heard if you want to keep them for decades get them onto photos as jpeg won’t last forever! I have family videos in Betamax but don’t have a working Betamax player to play them! Nothing lasts nowadays!😅Fraser😊

[@SeanBZA]

Well, a good use will be to use a Pi and run a clock through it, and project it on the wall.

[@BlondieHappyGuy]

Yeah, that would be cute. Besides the clock, perhaps having the Pi (or ESP32) reach out to a weather feed and display current weather data. Fun stuff.

[@patmitch272]

Might make a profit selling it working. Ya never know great video love your content

[@BuyitFixit]

Aww thanks Pat! 👍👍👍

[@599miata]

Like they say"Put brain in gear before body in motion"" When troubleshooting, if you start on the wrong foot it sometimes bite you in the behind. Great video none the less mate.😊😊

[@BuyitFixit]

Yes lol 👍

[@darrenwardell3079]

Funny, you normally check the power supply first. Glad you didn’t as it was good to see inside it.👍

[@BuyitFixit]

Quite an old video 🙂👍Thanks Darren👍

[@darrenwardell3079]

@@BuyitFixit i didn’t notice the video date 🙄

[@tomharris1457]

easy win! I wish the power bricks had plugs for each voltage instead of the same size for most anything. Also a standard positive/negative barrel arrangement.

[@BuyitFixit]

Yes, like those Stihl headphones I looked at that had a USB to barrel jack lead, and someone plugged a 12v adapter into them...

[@theshemullet]

If it's working in the end it's a fix. Just the problem was operator error by using the wrong power supply.

[@BuyitFixit]

I'm still not sure if the socket had a dry joint. But thanks for that! 👍👍. Next video is a proper fix and full diagnosis of a switch mode power supply.

[@rfisher79]

Thanks for making these Vids, I don't know what is wrong with me, I've been trying to find a side gig and I don't know why I didn't think of Tool Repair.... I don't buy new Alternators unless the Rotor is Shorted, id replace the Diode Rack and Brushed and i am off to the Races..

[@BuyitFixit]

Why not.. give it a whirl! That's all I did. It has taken a while for my channel to grow, but I've just kept plodding away at it 🙂👍

[@thetraindriver01]

It still surprises me when people just look for the connector size to fit and not the supply voltage, etc needed on the device sticker... oh well, their loss I guess

[@BuyitFixit]

Yes, same happened with the laser level I repaired but that was catastrophic over voltage 😂😂😂

[@elsaarmstrong-zp6ng]

Interesting videos though! Keep up the good work!😊 Fraz

[@BuyitFixit]

Thanks! 🙂

[@bikeforever2016]

🤣🤣 First guess was a power supply issue. But was taken by suprise that it went that way.

[@BuyitFixit]

Thanks! Yes it was cash converters that sold it on Ebay so I can only guess they got the power supplies mixed up with a similar one perhaps? I still think the power socket had a dry joint too...

[@JohnDoe-bd5sz]

My first guess was a dried out capacitor, this usually drops the DC voltage and the flickering was a good indication that it did not get the juice it was wanting. The wrong powersupply with only 9 volts is very much akin to what happens when the capacitors dries up, the DC component drops and the "AC" component gets bigger.

[@wherami]

Thanks!

[@wisher21uk]

I’m in South Shields Mick you sound like you’re up here too, I repair tvs, I’ve had that before on a 12v tv the power supply wasn’t the right one so it was collapsing when it needed more power. Great fix though shame about the quality 😂 probably £5 brand new from china

The cable labeled "TFT" is for a small 2-3" LCD panel from a 2000's cellphone, backlit by a small white LED. Absolutely junk :D

i like to ask what is the problem with the projector wifi is on but not reading any wifi signals. thanks

Faulty wifi module? No power to the wifi module? Bad Connection? Those are the thing's I'd be looking at.
