Thank you, Good information. it saved lots of time . Give you 7 Stars rating. *******

Genius - I had a "No HDD message" and spent the afternoon taking out the HDD, replacing it with another spare I had. Both HDD's worked fine on my pc connected to the USB. So I came across your video after searching online for solutions. Swapped out the power supply and hey presto . . it works like a charm. Thankyou so much.

Great video, I discovered by chance that my Swann dvr was no longer recording and I couldn't access the hard drive. After watching a different video and hearing strange noises from the dvr I had ordered a new hdd but then found this video, checked out my power supply and swapped for a spare I luckily already had and problem solved. Thank you very much👍

you're a legend my friend, you have just saved me around £50 there was me thinking the hard drive had packed up and all it was was a £10 power supply ,thank you very much for sharing this video....

Very handy, had the same symptoms, found a new power supply - all back up and running. Thanks OP, much appreciated

i just checked mine, due to this, i swapped the main power and camera power to it. HDD fired up, BRILLIANT. saved a few quid, THANKS

Thank you the video....awesome fix. I had the same issue after a few power outage. I replaced the internal memory and the system still was not recording. Just came across your video and swapped the power supply with a spare I had and the system fired right up. THANK YOU SO MUCH!!!!!!!

Absolute legend, I was about to fork out for a new DVR unit untill I saw your video..a new power supply later and it's all back up and running

My cameras were working but nothing was recording. After watching your video I changed the power supply and all is up and running. Thank you very much, sir.

Dont forget about changing the battery on the circuit board. Its easily replaced and its a cheap button type battery 3V C2032. I hoovered out all the dust and cleaned the fan with cotton buds then changed thus battery and boom it worked. No one on these videos seems to mention this battery and its a cheap easy fix. Thx for vid tho

Great info, checked 12 volt supply and it was low. Replace power supply and system booted normally!

Thank you so much for showing me the importance of actually checking my power supply first! This solved my problem as whilst the original power supply showed 12V it couldn't boot up the device but the replacement could. All without having to take the machine apart .Thanks again. So grateful!

My swann cctv dvr showed as 'dvr not connected'. I swapped the power supply and it works perfectly. I was going to buy a new system, you've just saved me a lot of money, thankyou.

Thanks for the valuable info. it saved my wreck. all the time i checked other parts without the p/supply. finally thanks to you my prob was in the p/supply.

Mate, I wouldn't have thought about the power supply at all! You can't take anything for granted! I replaced my HDD because my first one had appeared to have failed.. but when that one failed within a short amount of time, I thought it was too much of coincidence. Thanks for sharing your knowledge. You certainly have helped a lot of people 👍🏻😎

I was on the verge of buying a new DVR or HDD until I saw this video, I switched the power supply and, bingo, we are working again. Thank you for saving me £160.

Thank you Internet friend! Add me to the list of people you have saved the day for! Recently my DVR lost all video signal, I somehow worked out it was power supply issue and purchased 2 new 12V transformers thinking that the main unit's PSU was not far off dying as well. 6 weeks later I find myself in awe of your video, and I had a spare 12v Transformer ready to go! Thank you again!!

Thanks mate, that solved the problem for me. I work in IT, so i'm used to dealing with stubborn kit, but i'd never considered an undervoltage PSU. Normally, if the kit fires up, then the PSU isn't the problem. Every day is a school day... :-)

Thanks great information. i was just about to order a new hard drive and spotted your video. After testing i have now ordered a new power adaptor :0) my hard drive was working but the output had dropped causing multiple issues on the board and a slow running hard drive. thanks again all the best Jason

Brilliant!! Thank you so much for posting this! I thought my problem was a failed HDD, as all else worked fine. I am not very electronics savvy, but am willing to learn things, so I will often look online for a fix. I read somewhere that it was often the power to the HDD on a Swann CCTV. So i put on a separate power supply for the HDD, and hey presto it worked again. I thought that the problem was the power supply on the main board, not the thing that powered the whole box! Now i have seen your video i will try the more simple solution, changing the main power supply transformer! As others, i did not think these little boxes ever broke down! Thanks again!!!!

Just wanted to thank you. My error was No HDD and even when I swapped the HDD for a spare I had lying about, the same fault was there. I'm a DIY (Destroy it yourself!) expert, so I thought the unit was goosed and going to cost me around £300 for a replacement. When I did a search for what would be a good upgrade for a Swann DVR 4780, your video popped up. I've no tools and couldn't use them if I had, but I scrabbled around and found another 12v power plug. Swapped it over and voila! Sorted. Swapped out the 'new' HDD for the original one I'd taken out earlier and I'm well chuffed. Thanks very much again for your very helpful video ;0)

Thanks for the video. My Swann DVR9-4200 hard drive would not give me playback. I clicked on Device and then Smart and it showed nothing. I thought about buying a new DVR and then got to thinking about replacing the hard drive only over a period of days messing with it. After seeing your video, I tried a new power plug and everything worked. I never dreamed it was the power plug because I still had video on all cameras, but no recordings under playback. Smart under Device shows all the information now and says "good" like its supposed to. You saved me a lot of money and I really appreciate you posting the video. Bless you!

Thanks for that, I’ve changed these power supplies 3 times now over the years then they boot up properly and record!

I would have never guessed a power supply can ever fail, however mine did. Thought they were built for life lol. Good video and thank you

Same as a few others, this video solved /resolved my problem. Although the first spare 12v power supply I tried was only 200mA and wouldn't work. I then tried a 500mA and it worked.

Many thanks for uploading this video. I have a sannce cctv system and it had gone down and wasn't doing nothing. After watching your video I switched the power lead to one of the two camera power leads (made sure they were the same output first) and then.....bingo system powered up and working fine. I've put another 12v power supply on the system now and all s good. All just as I was about to order a new cctv unit. Many thanks again saved me £££££'s.

Thank you so much, I went out and bought a new hard drive today which didn't fix the problem, wish I'd watched your video first, it was the power supply. Thank you :)

Great video, it helped me get my system back up and running again. Thanks

Thank you. This is the exact problem I had. Switch out the power supply and its working now

Great video, 1st thing I did was try a new power supply which fixed my problem, thanks.

Thanks great video and great help my system stopped working last week and it was the power supply did not think it would be a five minute fix.

Not sure if that's my problem yet, but explained perfectly, many thanks!

Excellent video, diagnosed my PSU had failed, many thanks

You look like a real pro. Very logical diagnostician. I wish I could send you all my dead electronics. Off now to check my power supply.

You are amazing. This solved my exact problem

Exactly the same happened to me with the 48v power supply to my SWANN 8 camera system. Thanks for this - you helped me sort out my problem. I just bought a new power supply on Amazon and the problem was fixed

Thanks so much my swann dvr8 1500 had no display just a flashing red light. Watched this, swapped the power supply and now working!

Brilliant thanks. I was getting the no HDD message. Decided to swap over the SATA cable, remove HDD and plug into PC. Could see it fine, reformatted and ran chkdsk. Still nothing. Finally swapped out the power supply and BOOM it’s working. Thanks so much, going away for 2 weeks tomorrow and need them working 👍

Great vid, you just saved me a 2TB hdd, it's working again now with a new power supply.

Top Man. Problem with DVR. Checked HDD. no improvement. Watched this video. Changed PSU. Voila - result. Many thanks. As a radio ham I should have known better and checked voltages 1st!

Thank you, I changed power supply and it fixed the problem. Thanks to you I didn’t buy a new hdd.

Awsome this worked Iv got a Swan cctv I got from maplin always had issues with it not recording and saying HDD non exists or it would record for a few hours then stop. And then batter up and wouldent record again. Iv had 2 HDDs still same thing. Iv just put a different supply on now and boom cranked up straight away recording. Original plug was right little and crappy

Great work changed power and all problems with hard drive sorted. Thank you very much, saved me from spending $600.00 on a new base station.👌

Good info, I replaced the HDD and then I found your video which solved the dead HDD problem. Thanks heaps

You're the best Mate! Had the No HDD warning, but system and cameras on. Checked as per you video and yes the power supply was at 8v. Got a new power supply and fixed. Thank you!

Thanks pal, very informative. Saved me wasting money on a new system.

Changed the power supply and the HDD is back in action!! Thanks so much!!

It may be outdated but your video helped a lot, thank you.

mate your 100% right I have the same issue and you help me to fix it I want to thank you very much for this vid all the best

I rarely leave comments on videos - but I have to say how staggeringly helpful yours has been. YES - it was the power supply. NO - I didn't suspect it, because apart from the box reporting 'no hard disk found' it appeared to be working OK. YES - I had gone to the trouble of swapping the disk for a known good one. The offending PSU was relatively new, having been changed a couple of years ago as a result of the box constantly attempting to reboot but never fully powering up. Again this was difficult to diagnose (but somewhat more obvious to assume 'power') because the PSU metered 12V on no load. Going to ditch the 'fag packet' Swann adapter and source something like a 5A laptop adapter. Thank you again for your help.

hi and thank you I had the same to day and after watching your video saved me some money and it's all working again thank you again

Thanks heaps for this. I was ripping my hair out looking for the problem. brillant, absolutely brilliant

thanks so much for this video-like most here, replacing the power supply worked. in AUS i used this one 240V AC Adapter to DC 12V VOLT, 2A AMP w/Standard 2.1mm Inner/5.5mm Outer Plug. immediately removed the red 'no hdd' sign, and hdd lamp started flashing on box. great:)

Mannnnn, you are awesome. I bought a HDD and had the same issue. i looked at the voltage but didnt think it matter and i used a new power supplky and it worked!! thanks

Changed the power supply and HDD is back in action - thanks!

cheers for this video...... I'm going away to check my power supply ....fingers crossed

Thanks man. Great vid that has saved me some £££

Thank you for a most helpful vid. I'd like to add the extra fan on my 'same' unit. Can you show us, in a brief vid how you did this and where you tapped power from?

thanks mate helped me heaps, good on ya

Thank you, Amazing, wish I watched this before changing drives

Thank you sir! Precisely the issue.

Good job, thanks mate, just fixed mine, before watching this video, I was thinking the unit is broken.

thank you, was having the same issue, tested and was the power supply.

NVR-87082H, very similar main board to the unit in this video. On connecting power, No HDD activity at all, PWR an LAN lights blinking at 2 second intervals. Checked switch mode power pack, 12v present. Checked for 12v on PCB at the back of the power receptacle. No voltage. Hooked up my bench supply and she fired up straight away. Switch mode plug packs are proving to be very unreliable. Luckily, it's only a $20 fix for a system that cost me $800.

Thanks for this video. I almost went out and buy a new one. It was just the power supply.

I have just had same issue my hard drive wasn't working swapped power supply with the power supply for the cameras and worked straight away they send 3 power supplies 2 for the cameras and one for the unit the ones for the camera have red plugs never really took much notice the one for the unit is a black plug maybe the power supply you was testing was actually for the cameras and not the unit but watching your video had me checking power supplies

Thanks - helped me out - great simple video 👌🏻

superb! video... and that is very very expensive multimeter

Thanks for the video the next time just come on and say Hey guys you need to change the power plug that's all you have to do

Thanks for this video mine was the capacity. Luckily I had one. 🎉

You are absolutely correct. Thank you so much. It fixed it 🥰😁😘

Thanks man it worked

April 2021 Enjoyed the video & follow up. Can only agree but also found another problem you might be able to help with. On these Swann DVR 1425 boards also find Y16 close to the onboard battery gets cooked with the same problems. Wondered if you can read or know what Y16 is, please (besides it just being a crystal) Thanks!

Thankyou this saved my system I was going the Chuck the system out

IMPORTANT SWANN OWNERS READ THIS , your set up will come with 3 power adapters 2 are rated 2 amps 1 is rated 1 amp You need two adapters for the cameras and one for the DVR So god only knows why the one you need for the DVR is rated at 2 amps , leaving a 1 amp and a 2 amp to power the cameras , no wonder the DVR keeps failing on a 1 amp adapter , Swann label which is for which please Moral of the story is 2 amp is for the DVR !!!!

Hi. very good video. Im wondering if you've ever experienced a Swann DVR fault where the video input is all wavey? I checked the cameras direct to a monitor and thats fine. Also the menu screens are crystal clear, so I assume its on the input side of the DVR. I've tried anothet powet supply as a quick fix but issue still remains. I'm guessing some sort of earthing or capacitor issue but any pointers would be great? Thanks, Dave

Thank you, I just got the hd working.

Ha ha! Brilliant. Simple as that. Thank you so much.

Thank you so much 🙏👍

We have the same issue but did not realize it until someone had broke in and we tried to pull the video. It had not recorded anything.

thanks for sharing

Great advice

Hi there having same problem, hard drive stopped & the fan there was a bleeping noise but that has stopped , just ordered a new power cable will let you know if that sorts it cheers,

Hi I've got the Swann recorder 8 channels and in the last 2 months I've put 4 new Hard drives in it and it keeps screwing them up? There's a red H symbol at the bottom every time I try to format the HD When this sign appears it doesn't format but when I first put another working HD in the unit it formats and works for about a week?

thank mate working thank to you

Hi, great info video. I suspect my power supply is doing the same - The adaptor is reading just over 12v but that's the disconnected output, not a reading from internal. i have a spare 12v power supply but it's rated higher than 2000mA, can I use it or do I have to keep to 2000mA. I think the other one is 2.5a, Appreciate your advise. Rich

thank you lots of help fixt my h.264 dvr

Mine has the same problem. Have just ordered a new one. Never come across this type of failure before. Usually a psu is either dead or alive 😄

Thank you

Hi Thanks for this as I had the same fault and since been rectified by new power supply, Great Stuff, Just out of interest where did you get the extra fan from and what size is it?

First off thanks for this video ,,,,,So I called swann and they told me to unplug my camera power adapter and plug it into the power port of the DVR it loaded the desktop but I still could not format the drive hmmmm ?. So I took the HD out and running test on a PC everything check out the SMART , surface test and even coping to HD works so any ideas ? The camera power supply is the same volts and amps and it still wont format the drive ? I'm getting 3 long beeps and 2 short any ideas would be appreciated thanks.

Thanks, my power cord was faulty.

I'm having problems with my Swann DVR not working and have contacted Swann technical help, numerous emails back and forth over a week and not once have they mentioned the power supply, meanwhile I've ordered a new one and awaiting delivery.

My problem is nor recording or playback ability. Anyway maybe a good start to check power supply reliability.

Hi there again, it's me Suzanna from Mexico. The power cord that goes to the dvr is 12V 6a? or 12V 5a? My Dvr won't start again. Gracias from Mexico

Hi just wanted to ask would the voltage number on the plug if its bad? Should the voltage stay at 12v around that all the time

it would be more helpful to have the video camera on what you were testing. Thx.

ahh, cheers. I thought the whole unit was snookered and packed up. seems it may be just the PSU. I'll probe with a multimeter tonight. you may have saved me £150-200

I'm on my second power supply now. The original Swann one blew up so that was garbage and the £30, yes £30 replacement that Maplin told me would be the only adapter to power the unit has now either blown up or the Swann unit itself has blown. Either way I can no longer monitor my home while at work so I'll never buy a garbage Swann product again. Never!

Hi, be grateful for your advice. I've got a similar problem with my Swann NVR. It's got the same board as the one in your video. I've got a Peak Electronics ESR meter and have checked the caps and all seem OK except one of the 220uF SMD caps which says leaky/in circuit so I removed it to test it and found the one leg just came away from the solder so I thought that was interesting. Anyway, tested it and tested OK so soldered it back in and retested. It gets to the Loading screen which goes blank and then does nothing. I've tried it with another HDD and get the same. I swapped that 1000uF cap with a 1200uF, closest one I had but still doesn't work. Can you tell me what voltages I should be seeing from the regulators? getting 5V1, 1V1, 1V4 & 3V3. middle two seem odd or are they references. HDD voltages are as they should be, 5V1 & 12V. I've found the same problem with cooling as you have, the system would just crash, I found the heatsink was excessively hot so left the lid off. If I can get this working again I'll have to fix a fan like you have there. Anyway, again, would be grateful for your advice, Thanks.
