Lorex HD DVR no power Fix

Fixed my lorex dvr that died one day. No power no boot fix for lorex dvr.
Turned out to be a bad power supply.

[@MoisesCarmona-ji5gi]

Thank for your video I got my security cameras working I did your test and it was my adopter. Thank you my unit is working.

[@AJ-ti3du]

Lorex has a prolong and serious issue with listening and responding responsibly to its customers. if this fantastic ukrainianbear05's web site was not available, more than $500 would now be wasted. A 12V 4.5 A solved my stalemate, due to a power outage. If in fact the owner of this site is an Ukrainian, GOD BLESS you and all your sympatries.

[@LyuLefterov]

Thank you for posting this! Our old 480p wireless Lorex DVR quit in a similar fashion, I think right after a power outage. I tested the power supply and it showed proper voltage, but after watching your video I was skeptical still and tried a different 12V power supply (a little lower amperage) and that confirmed exactly what your experienced. These 12V power supplies seem to be prone to dying after a power outage. I'm ordering another one on eBay as I am typing this. I'm glad I was able to revive our system and save myself the $800 price tag of buying a brand new system now. It's only a deterrent for us anyway and we don't actually rely on being able to get license plates and facial recognition from our system. Thank you for sharing this quick and cheap fix!

[@zeekhan1844]

Excellent i was having same issue with one of my friends DVR, and is now resolved thanks for posting this informative video.THumbs uppp

[@steveanderson949]

Had the same issue short power outage and dead lorex had several other powercords and bamm back in business thank you so very much saved a lot of time and money

[@varunvasudeva6465]

Thank you. Tried changing the hard drive, still not getting enough power to boot up. I actually used one of the extra power plugs from the multi-plug camera adapter since I am not using all 8 cameras. Worked like a charm. Now I just have an extra hard drive but can't hurt to have a backup drive handy.

[@shawnb2927]

3 years later, still helping people solve the problem. Used the power supply from a neck massager, DVR works like a champ. Ordered replacement from Amazon. Although, everyone can start at 5:00 and get the answer by 5:45.

[@nikfaguy]

I wasn’t having the same exact problem but you did help me a lot to figure it out. Thank you

[@bobbie_2020]

I don’t know if you are still reading comments but I wish i saw your video about 6h of frustration ago! You saved the day, thanks so much!!

[@TehArtfulDodger]

Good to hear this old video is still helping people 😊

[@enriquedeleon22]

Thanks man appreciate the help! My dad is happy his camera system is back up and running. Take care.

[@amarrambhajan8001]

had a similar with my lorex DVR exact same model. just it was the power supply for the cameras. threw the old power supply out and replaced with a old Toshiba laptop power supply, and works and been working over 4 years now.

[@heidiklose4525]

You made our day... Exact same situation even purchased frim Costco. Plugged in another power supply and worked. Thank you 1k times over for posting and sharing!!!

[@ChynaWhyte90]

I was about to spend hours and who knows how much money trying to figure this out for my night owl system. Thank you for sharing. Apparently power supply has surge protection!

[@TehArtfulDodger]

Glad I could help!

[@JesusLVR]

thank you, i was going to trash my dvr but replacing the power cord worked. even though my electrical tester said my dvr was getting power with the old cord i guess it was not enough power. you saved me alot. thanks again.

[@elikag7844]

THANK YOU! You saved me from a new DVR and hard drive. First the hard drive stopped being recognized. Then a few days later, the DVR would not power on (but did have a long beep). Had an old netgear power supply for a router and everything is working like new. Thanks again!

[@Mick_T63]

Thank you very much. I have a zosi cctv and the same thing happened to me. Luckily enough I had a spare power supply and it works great now. 🎉👍

[@MrChad10001000]

Thanks brother saved me from buying a new dvr thought mine was smoked after a power surge

[@jamesholt2847]

Exactly the same as mine, swapped with a Hard drive power supply and it worked, Ordered a proper replacement on Amazon. Looks like the power supplies have about a 10 year life time. Which when left on for 24/7 isn't bad.

[@TehArtfulDodger]

Glad I was able to help friend

[@muchosa1]

Your video helped me. Mine was also a bad power supply.

[@anthonygodfrey6131]

Thanks for this. Had a similar problem with my sannce unit.Swapped over the power supply, problem solved. I was about to strip the dvr down, so thanks again for this saved me a lot of wasted hours.

[@y2ksierra]

Awesome. Had one laying around from an old DVR and it booted right up with the non-fried power supply. Thanks for this video!

[@jaimek6090]

Thanks this resolved my issue as well. Have a Dahua DVR that kept blinking with red light and would not start. The issue was also the power supply.

[@orosilodge9974]

Same problem here - changing the power supply fixed it. Thanks for your video !

[@AlfonsoTorres796]

Your video came in real handy. Solved my issue with my cameras by switching to another power supply. Thanks

[@lifeisonebigsymphony]

You took the board apart to figure out a bad PS. Kudos man!

[@arabgaming151]

Thanks bro. I got an LED light and connect it to the AC the LED was blinking as the light was doing on the Dvr

[@mapleroadsessions8806]

Thanks so much. Had same thing with ours and just fixed with another supply. I was ready to trash

[@chrispracticallife4980]

Great video. Just had the same exact problem. You just saved me hours/days of troubleshooting. Was going to start taking my Lorex receiver apart, but your solution worked! Lorex needs to provide better quality AC adapters. Thank you!

[@veequattlander5296]

Thank you for helping me find the easiest solution to this problem. ..And to think I almost threw out all those old plugs.

[@JM-xh1zn]

Thank you for your video! Mine kept cycling on and off. Remembered I still have an older DVR system from another brand, sure enough same size power supply. Works again.

[@user-oy1gk8is9o]

You sir are a GENIUS....same problems with mine and was fixed in minutes after checking the capacitors. Have two others with the same problem and I bet this will be the solution for them. Thanks for posting

[@donnasandford6727]

Thank you very much!!!!!! I will fix this before husband gets home from work!!! LOL !! He will be amazed by my super power ! (eventually I will confess the ease of repair)!! Thank You !!!!

[@michaelmcguire5273]

Sir, I wanted to take a moment and say thanks. Like you have a knowledge of electronics and feel comfortable working on them but if a board component need replacing I will leave that up to the pros. I had a similar issue with my system from Costco. The power came on but the board, determined later was under powered by a failing power block. After removing the cover to my system, I observed the board fan turning very slow & HD not spinning up. A quick search on Goggle and pow your KZbin post came up. I had an extra power block from an old system and poof the unit powered up and functioning like new. Thank you for your time in recording and posting your information in regards to the Lorex DVR systems.

[@drTWO7]

Man this video was awesome! Switched the power supply and im working again. U saved me alot of money! Thank you

[@williamchupin7872]

thank you finally my camera dvr works

[@p2theaul]

Worked for me. Thanks! Now if I can find a way to quite down that darn fan I'd be happy.

[@keeganb868]

Just saved a bunch of money by just switching the power supply. Thanks for sharing the video!!

[@onthebrakes]

Thank you for this post. I thought I needed a need hard drive. My power supply was bad, instead. THANK YOU.

[@MyCroWave2]

Thank you. Replaced the power supply and it's working properly again.

[@manar424]

Thank you!! I was afraid I had to buy either a new system or dvr. Replacing the power cord was exactly what I needed to do!

[@michaelrenninger4323]

Thanks. I have the same DVR and the same problem. This is amazing the similarities in the steps I took to get to the same point in your video.

[@MrSergio1159]

thanks for the feed back I had the same issue with my lorex and switched the power supply and it is working now, thanks ones again

[@eason3422]

Thank you !! im already planning to buy another one. Got it running after replacing the power adapter. Im not suspecting it to be the power adapter since a LED indicator inside the board is lit steadily. Thanks again !!

[@christopherlong2301]

Thanks for this video. I have been searching all over for an answer. I have the exact same symptoms with my HIKVision DVR. I checked the voltage of the ps and it seems ok but didn’t try it under load. I’ll try a different ps tomorrow.

[@buddygrant8029]

Your the man. Thanks for the quick fix and just saved me hundreds.

[@matthewa9694]

this worked for the night owl security camera too...thanks man

[@jamesardoin5906]

Nice video. Thanks for the info, I never thought of that. Just for record, 2.5 amps and 2500 milliamps are the same. No metric terms involved. Also, don't use a 9 volt power supply because the lower the voltage is, the higher the amps drawn are. It may exceed the amp rating of the circuitry on the board.

[@UpnorthHere]

That was hilarious! "Metric". Right -- as compared with the olde English system of standard amps or volts.

[@TheAlhdabi]

Man you are a life saver The same thing I did and it worked Thank you God bless you

[@seapeddler]

Also upgrade the power supply splitter to the cameras. If the video goes blank or there is color bleed, it may also be the camera power adapter.

[@dylanmcleary6703]

This help me with a zosi dvr thank you

[@stevenweede7184]

I can’t tell you how many power adapters I’ve had to purchase between my Lorex system & my mom’s. I’ve had to replace AT LEAST 8 camera power supplies on mine alone & one DVR power supply. As of right now I have my mom’s NVR & believe it’s the same problem here. Great system, but whoever makes their power supplies is HORRIBLE though

[@TehArtfulDodger]

Would recommend an apc continuous power supply. Gives you emergency power when the power comes off and filters your existing power from voltage spikes ect

[@katiel1682]

That was it! Unit works like new again. Well that saved me a few hundred dollars!

[@ugsisr]

Very Good... So now your Troubleshooting skills have also increased.....Next time you will check all external components before looking into internal. I would purchase a 2.5 a 12 vdc power supply... Take care...

[@Rock161]

Thank you. I tried mine and it worket. Thank you you saved me a lots of money and time

[@userman444]

IT RESOLVED MY CASE TOO ! MANY THANKS !!!

[@AD-pi4dk]

Thank you somuch for posting this very help full video special for me I had the same issue.

[@lonnytate2826]

It didn't work 1st or second time but I notice amps play a role. Just not 12v. The 1sr 2 trys it worked bout 1min then shut off so I found 1 with higher amp. Now it good. Thanks bro

[@bjorndavid3206]

Thank you so much...just saved me loads of frustration.

[@marynadasi1745]

This was perfect, thank you. saved me lots of money and time.

[@TimeinMoment]

Going to try it and see if it works thanks.

[@stuartnicklin8767]

Thanks this happened to me too and save me a load of money on repairs.

[@gabegarcia622]

Thanks save me a headache and lots of money.

[@SeleniumTeck]

Positive and negative shuted, no power, the power source is good what could be the problem

[@1.8tfrankenturbovw42]

Thank you! Worked for me. I almost bought a new one.

[@friscolianrick8224]

Thank you like every other comments great information fixed it right away

[@impulsesystems]

The stock power supply is under-rated, so it can overheat. I replaced mine with a [same voltage but] higher current rating model and the problem went away. No tear down necessary! Sorry you had to go through this!

[@IWANASLAPTHAT]

Hey Bud, great video, save me loads of money so thank you very much. new power supply and all works well again. many thanks

[@TianJiang96]

thank you so much, I almost spend over $100 to buy a new box.

[@michaelrife2260]

Thanks!! weird, was watching the video and my camera started working again and I didn't do anything, going to go and get a new power supply though just in case it dies again. mine would start up and then shut down within a couple seconds before it showed up onto the monitor so I didn't know if it was the camera system or the t.v.s hdmi not working. thanks again!!

[@ElBuzonMusic]

THANKS!!! This video solved my problem!!

[@onji]

Thanks man. I was getting ready to buy a new system after a drive 'failure' and replacing the drive didnt work. This got it back going. Detecting the drive again. wtf lorex

[@TheBobbyb1967]

Nice video I am having a similar problem. My dvr wont turn on but when I test the adaptor with a multimeter it shows 12volts output. I wish you would have showed us a test of the adaptor first. I happen to have an another adaptor that i use for a police scanner i just have to find the correct attachment for it to switch it to 12v . Wish me luck i hope it works.

[@shapushnnon]

Did you fix yours? Same problem with mine.

[@TheBobbyb1967]

@@shapushnnon yes I bought a new power supply on Amazon and it fired up.

[@ExceptionalServersIncBabylon]

Thanks so much, I was going crazy trying to figure out the issue. I had the same blinking when HD was detached. Changed the power cord and viola! Works fine. I too had a power interruption so must've blown the power cord. Thanks saved me a bundle.

[@SamuelEbinezar001]

Thanks buddy, you saved my time and money.

[@MiguelChami]

Thank you!!!! Thats exactly what it was!!!!

[@claudiagonzalez-fg1li]

I had the same problem, and i did exactly what you did and same reaction,lol. Thanks so much ,i know now that it's the power cable.... btw my system is a zmodo.

[@SketchyAJT]

Worked for me on a Zmodo DVR!! Thanks!

[@JoshuaCaplan]

I have replaced the stupid cooling fan on this board twice now, so when it started emitting 4-second-long ear-splitting beeps at 2:30am a few days back I figured it was time for another one. Alas, it would not even turn on this time. Wish I had tried swapping power supplies before opening it up again.

[@boeingc1303]

Perfect he works thank you you save me a lot many Body

[@elbertsoguilon1405]

Thank you so much, you made my day,it works try with another power supply.

[@rebekahangerer4461]

I have one but only 4 of 8 work. All of sudden the 4 just quit. How to fix it?

[@jog5075]

Im going to try in my swann with the same problem i let u know men thanks a lot

[@RafaelCifuentes]

I replaced my power supply with a 12V 4000mA. Still not working. Any suggestions?

[@rafikbatroussy1250]

Believe it or not, in my case it was the wire connecting the adapter to the electricity plug that was defective. The adapter itself was ok. When I changed that wire connection my DVR worked again normally. That's so tricky and frustrating, specially that with the defective wire the whole DVR sometimes turned ON but it did not detect the hard drive to save the recordings.

[@aperson1181]

I just came across your channel. Would you please help? I bought a system from a store a few years ago and it worked, then one day the recorder stopped working completely. I don't know what to make of it. LNR6108x-n is the recorder, how to troubleshoot it? What could go wrong? It is not a power supply, it shows 48v

[@parmeetkarwal9501]

Wanaa buy you some beer ... thanks .. nice video

[@PhulpreetSingh]

Thank You! That saved me hours and Money $$$

Use multimeter to check dc adapter to check the voltage

Anyone know where the factory reset button is located on these old lhv2108s? Picked up a used one and no password…

[@ionutstavar]

unbelievable it work.... thx best ever

[@farrellloebbaka506]

Same problem here! Thanks!

[@kayceebrown1]

Hw came I factory rest set my lorex DVR please

[@richard5981]

I’m hoping you could help me. My case is a little different. I could hear the fan working I see the word power licked up but no matter how many times I press the power button I don’t have nothing displaying on my TV. It doesn’t connect to the Internet. Please ask Si and I don’t have the money to replace the system I will pay my aunts cancer treatments and I’m very tight on cash What can I do to fix it?

[@TehArtfulDodger]

Chech if the harddrive is the problem

[@RPCTVPhilippines]

same as NVR lorex?

[@dennismozeleski834]

Going to Amazon now to find one. Thanks

[@franciscojaviercervantes5329]

Thanks. Fan did came on but still not working. Hard drive is bad.

[@bigmike1556]

After a year and half the adapter went .. changed it and up and running.. at the 2 year mark the fan stopped cooling and would hit the high heat limit and shit down. Replaced the fan thanks to Amazon and it was up and working... now at the 3 year mark there is power at the display but no signal from the cameras... just happened. Tried another ac adapter and still just beeps and no signal from dvr to TV. . I only have the power light on the front display on. I will look at it tonight and if cannot repair it .. i will never buy a lorex ever again .!!!
