FAULTY Swann CCTV NVR / DVR No power - Can I fix it?

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!

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.

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!

Great stuff! I wonder if the power cut or temporary power supply caused some kind of surge into the unit? I wouldn’t have thought a power surge would get past the laptop-style power supply? I wouldn’t have have expected the 48v power supply to be taken out first. Strange!

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

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!

Cracking fix, stroke of luck noticing the IC blown straight away 👍😊

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!

Ah the classic bolt stuck, wrench slipping hand scrapping against metal look on your hands, but a nice little video and great result😊

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.

[cajuncoinhunter]

Those are sure nice to have around when you have a large house you want to try and keep secured Just the thought of cameras keeps the thieves away most of the time Nice and fast diagnosing on that one Take care Mon Ami ....

[collettep]

I have learnt so much here. I don't have the tools to fix my cctv box as in the video but would love to know if you do any repairs for others or not? Thank you

[robertchiew]

Please can you let me know where you purchase the spares, as I have the same issue??? Thank you for a great video.

[Arachnoid_of_the_underverse]

Very nice fix Mick, you saved it from the junk pile.

[jaylo]

Got nearly the same one at home here. Good bit of kit . Great video again. Thanks

[scott]

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

[wisheruk]

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

[brianvincent]

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.

[Popeyes]

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 . . . . .

[steveharvey]

Once again, a delight to watch you in action troubleshooting and repairing with such skill. My only concern here is replacing that larger package diode (SMC?) with a much smaller one (SMA?). Did you consider that the power dissipation might be an issue with the smaller package?

[mickwolf]

So it had a shotty schottky, nice work.
