FAULTY Swann CCTV NVR / DVR No power - Can I fix it?
Вставка
- Опубліковано 29 кві 2023
- A friend asked me if I would take a look at his Swann CCTV NVR (network video recorder).
During a storm he experienced a few brief power cuts before being left without mains electricity for a week. When his power was fully restored, the unit no longer switched on, and was completely dead.
Let's take it apart, see if we can diagnose the problem and hopefully repair it!

Good people doing good for others and the environment. I have enjoyed your channel beyond meager words since I found it!. seriously, it's the thrill of the chase, the suspect (components) the investigation (shorted? grounded? open?, overheated?) the diagnosis and repair. Truly refreshing when click bait and garbage are more and more what we endure till we are exhausted!!
None of that here! Real (good) folk doing the Lord's work helping others and saving this valuable stuff from the land fill!
Keep the good videos coming and keep being a good guy who people are excited to follow.
When that screen lit up so did my face. A large smile and "yes!!" emerged.
Thank you Mick for such uplifting work. In a throwaway age this is way better for me than the dull grind that is so much of what other channels crank out now days!
God Bless!
Really appreciate your kind words and feedback John 👍I also volunteer at the local repair cafe to help people in the community repair items. There's a group of about eight of us and we all have different skills repairing anything from a torn dress, a petrol lawnmower to a games console.. Thanks again and god bless you too 👍
Thank you! I was about to place an order for a replacement nvr8580 that suddenly died. Followed your advice and found the SS56 diode was a goner. The nearby buck chip looked ok. So onto Mouser and bough ss56 and buck chip. Soldered in the ss56. And it works!. Woo hoo. A 25pence fix !. Just subscribed!. Great channel!
Thanks 👍this is the reason why I make repair videos. I'm really glad it was helpful to you.
Thanks for the video mate👌
I’ve been waiting patiently for about 18 months for a legend like you to post a fix. Ordered my new component put it in, and I’m back in action. If only Swann helped out their customers like you have.
Thanks again.
Cheers
Chris
Brilliant news Chris! I'm so glad I was able to help someone else repair their unit! That's why I make these videos! Well done 👏👏👏👏
You are a gentleman. I love how you do your bit by saving many things from going to landfill. May you grow from strength to strength in all that you do. Kind regards. Paul.
Thanks Paul. Best wishes Mick.
Cracking fix, stroke of luck noticing the IC blown straight away 👍😊
Thanks, yes although if it's a no power type of repair, I'd normally start where the power comes in and start working from there, so it wasn't really that far into the circuit.
Nicely done Mick 👌
Thanks Vince 👍
Great video as always.
Thanks Tony 👍
Very nice fix Mick , you saved it from the junk pile.
Thanks Andi 👍 Yes, another item saved 🙂👍
Perfect repair!
Thanks Lukasz 👍
Got nearly the same one at home here. Good bit of kit . Great video again. Thanks
Thanks Jay Lo 👍
Good troubleshooting.👍👍
Thanks 👍
Great job well done dude.
Thanks Dave 👍
Good work. very helpful. thanks
Glad it was helpful!
Those are sure nice to have around when you have a large house you want to try and keep secured well..... Just the thought of cameras keeps the thieves away most of the time ..... Nice and fast diagnosing on that one ..... Take care Mon Ami ....
Thanks Cajun! Take care too!
Great fix, thx for video.
Thanks Tomasz👍
I really need to get me a thermal camera. I've almost wore out my soldering iron by lifting components to test for the short. You make it look easy, but I know you have struggled through things to get where you are today. Awesome fix again sir.
Thanks Ron 👍
I just bought the Kaiweets Thermal on Amazon and it's fantastic. Normally lists for 300, they had a "limited time deal" for 240, then an additional 10% off right now, then there was some other promotional 10%, so I got it under 200 bucks.
Ah the classic bolt stuck, wrench slipping hand scrapping against metal look on your hands, but a nice little video and great result😊
Oh yes and trying to get hands into small spaces with sharp bits of metal!
Thank you for this video! I bought a new PSU as the DVR had some power, just not enough to power up. That wasn't the problem! Using this video I found the 68uf capacitor at the power input was ever so slightly bulged and didn't notice before. I didn't know where to check the voltage and the test you did at the 2:55 mark gave me 1v, so I knew it was the cap. Thank you!
Really glad it helped. It's part of the reason why I make them so if people come across the same problem they have a chance of fixing them. Well done on repairing your DVR and thank you for the feedback 🙂👍
Took three months to eventually get the capacitor, but that didn't fix the issue. The diode and the silver square box above it (the inductor?) get bloody hot. I've waited so long for the cap and to not have it work is heartbreaking. I'm not knowledgeable enough to know if I'm testing shorts, but I'm assuming the diode is dead like yours. Fingers crossed, delivery is estimated for 4 to 8 weeks. @@BuyitFixit
The diode should measure a reading one way, and nothing when you swap the leads around. If you get a low reading both ways then it has gone.
Thanks Mr Fixit! I've packed it away out of bitter disappointment for now and beginning the hassle of finding a single diode and not a reel of 100! From memory it had a resistance of 1000 one way and 700 the other way, and with power it's reading 4v instead of 48, but reads 48v everywhere before the diode. The chip looks fine visually, but if the diode doesn't fix it, I'm giving up and looking online for a second hand one :) Your video has been such a huge help, thank you!@@BuyitFixit
Thanks 👍if you get stuck, and would like to email me some pictures of the area of the board I'll try my best to help. It's been a while since looking at this so I can't remember 100% what the circuit layout was but I might be able to help you diagnose a bit better.
Thanks for the video Mick, really enjoyed that one. Those thermal cameras are handy things, i've still not found an excuse to get one
Thanks Scott! Glad you enjoyed it 👍
Thanks Scott! Glad you enjoyed it 👍
Well done Mick nice fix I was going to say about power spikes taking it out, but surely the power supply would of suppressed them
Thanks Cucumber Man👍 Yes I thought the exact same thing. It is a bit odd unless it was just a coincidence?
@@BuyitFixit we will never know Mick lol 😂
So it had a shotty schottky, nice work.
Thanks Mick, also a blown regulator IC too 🙂👍
Very nice
Thanks Audi Bell 👍
Thanks 👍❤
Thanks to you too 👍🙂
Brilliant! Just the video I was looking for. My Swann NVR-8580 controller stopped working. Checked it with the DVM and found a short circuit across many capacitors which I guess means the DC rail is shorted. A thermal camera showed overheating of both the SS56 diode and 54360. Removed the diode and the short disappeared. Waiting on delivery of the diode. Hopefully that will fix it as I dont have facilities to replace the 54360.
Hopefully it's just the diode.. if the chip has failed and you don't have the equipment I'd suggest possibly a local repair cafe if there's one in your area? I volunteer at our local one where people bring in broken items, and we try to repair them and they can give a small donation if they wish. If not then perhaps a makerspace or something might be able to help. Let me know how you get on as it would be great to know my video helped you successfully repair it! 👍
So ? What was the problem with yours ?
I’m in the same boat with 2 nvr16-8580 ! I don’t have the equipment and I’m on the edge of buying a new Lorex kit 😅
Thermal camera makes it so much easier than the back of the finger test huh Mick.
Another great fix,even though the DC-DC chip was an obvious fault due to it having a fair sized chunk of it missing.
The problem is waiting for spares in my case.
I now have a dedicated shelved cupboard for thngs waiting for parts to arrive,otherwise you can end up with a right old state of a work space.
It's good to have pals with broken stuff to give you more content i suppose.
Hope he buys you a pint or 2 or 3 or . . . . .
Thanks👍. Yes the thermal camera is great for finding shorts like that.
I don't mind helping this guy out as he's a good friend and the one helping me rebuild the car currently. It's a Mercedes ML320 and oil was literally pouring out from the bell housing on the gearbox. Approx a good mug full after it was idling for a couple of minutes.
We had the gearbox out a couple months back and replaced the main crankshaft oil seal as that seemed like the likely cause. Refitted the gearbox, driveshafts etc, same issue.
Turns out a common problem with the OM642 engine is the oil cooler seals which you have to strip down a fair amount of engine to get to as its right in the bottom of the V (V6 diesel engine). We've had to remove the Air intakes, heat shields, exhaust pipes rear of the engine, turbo, injector manifold, injector pipes, inlet manifolds, swirl flap motor, wiring harness and god knows what else. It's a fair old job! and awkward as hell as you have to be pretty much kneeling on the engine to do most if it as the car is pretty high, and most of the stuff is at the back so you can't reach it standing at the front.
That's why my hands are in such a state. I also can't get away wearing gloves as I need to feel things like nuts and bolts.
It's been off the road for about 5-6 months now as I've had too much other stuff to do along with a couple of health related issues.
We've been working on it again today as I've got most of the replacement parts now (mainly gaskets), so hopefully we get it back working again sometime next week fingers crossed!
Good luck in finishing that crank oil sea repair.
They are a nightmare as everything has to come off to reach it unless you have a lift and can drop the whole lot out the bottom.
Takes me back to the 80s when i had my Mach 2 Capri gearbox balancing on a Express Dairy milk crate as i was laying underneath and using a cut off gearbox splined shaft to align the new clutch and tensing my belly up to push that bell housing home😂.
Took me an hour and a half from start to finish.
I wouldn't attempt it now though,i might not get up from under the car again.😁.
Good luck Mick & all the best.
P.S i used to use fairy liquid and sugar yo get the ground in oil out of my hands and nails.
Swarfega was always the thing i ran out of just when i needed it !
That's a very odd coincidence. My first car was a mk ii capri and I too remember lying underneath it and changing the clutch with a cut off spine off an old gearbox to align it too! 😂😂😂
Mental !
I wish you were closer. i have so many tools and things to be repaired i try few repairs my self but some are above my pay grade😂
Yes I wish you were closer too!
Hi sorry but I am watching your videos in reverse order.
Just wondered why you did not for the diode just scape the solder mask of the ample pads and solder it direct to the PCB, which would also be better for cooling the diode?
I do love the vids though.
Good Idea, and thanks for letting me know 👍
Please can you let me know where you purchase the spares, as I have the same issue??? Thank you for a great video.
Thanks 👍I think I got them from Digikey if I remember. Hope that helps.
If your friend had used a power surge protection bar, would it have prevented this damage ? Are those useful at protecting our electronics ?
I doubt it, as this has a power supply brick to power it. It could just be a coincidence or the power going off and on a few times quickly. A surge protector would have only protected the power brick as that's where the mains comes in.
I have a Swann dvr. Swann said the model I have is now discontinued. I changed the power adapter and it now shows a green light but the display on my monitor won’t move from the blue swan logo page. The dvr is now discontinued with Swann. I am not competent with opening up dvr recorder. Thank you
If the power supply you have used doesn't have enough amps to drive the hard drive that may cause the problem, or if the hard drive has failed. I think those are the first things I'd be checking.
60v 3.5amp dc - dc buck converter, chip, TPS4360
Yep 👍
I almost never get something so easy.
Luck of the draw I guess. Sometimes I get easy stuff, sometimes not so easy 🙂👍
It would be interesting to know a rough cost of the spare parts? I guess pretty cheap. I was looking at my father in laws wahing machine which was having intermittent issues. Appears to be the selector switch but when i looked it up i looked it up i could buy a replacement for around £1. Only problem, id have to buy 1000 😂
Thanks Jock. Wow 1000😧! I think it was about £5 or so for the parts. Thanks for commenting 👍
Is there anywhere you can send or take to a DVR in the UK to get it fixed please ?
I volunteer at something called a 'repair cafe' where people in the local community can bring broken items and we attempt to repair them for free (they have to pay for parts if required). There's a number of these across the country so they should be one near you. If it's the same problem as this, you could point them in the direction of my video as I know a couple of other people's DVRs had the same issue.
Does this have a factory rest inside the dvr
I'm not sure, I don't recall seeing anything like that.
i bought the same 8 camera NVR replace the power lead, with old one which was faulty, but its still not turning On, i am not Expert like you what shall i do to fix this NVR to turn back on, ? Regard
I'd check the voltage going into the unit, and see if you are getting voltage out of the regulator like I tested. If you're getting voltage in, but nothing from the regular then it has probably failed like in this one.
Hello. My NVR wont switch on via power lead. I’ve tried different power leads and H drives but still nothing. Would it be possible to fix my unit for me or have a look? Thanks
If it's the same model as this one, check the diode at the left hand side and see if it's shorted. I had a comment from someone else with the same problem and that diode was shorted.
Thanks for getting back to me. Mine is Longse NVR only a year old and all of sudden no power. I can’t see anything that could be wrong with. Your accent seem local, I’m in the north east..
Ah ok, I get messages from all over the world you see. Yes used to live in the Northeast but live over Cumbria now. I don't normally take in repairs. Drop me an email using the channel about tab and click the for business enquiries button.
where do you buy your components? If i go to RS they require minimum order quantities of parts. I don't really want to buy 100 if I only need one.
Some items are listed multiple times as a reel or cut tape. So there is usually a choice of 100 or perhaps 5 or 1. There's also Farnell, Digikey, Mouser, Ebay and Aliexpress. All have advantages and disadvantages just as potential fakes or expensive shipping costs. Hope that helps 🙂
How much do you charge mate haha mines broke i need mine fixed
Great Job I wish I can send you one of mine it has the same issue
Thanks 👍
Faulty. Swann. CCTV. NVR. DVR. No. Power can. l. Fix. It
That cap next to that black pieper also does not look healthy, is bulging at the top,
and yeah you also saw that, as always another great fix.
Thanks 👍
It's better to wait that everything is cooled of, because it can crack when you put
"cold" alcohol on it, when the parts are over 200c.
Just a tip.
Thanks 👍yes I had thought about thermal shock..
