Hey happy to hear you got it going! Glad I could help

Hello, While they may look the same, the DS412+ does not use the same type of intel processor and thus is not affected by this bug. This means the resistor fix would not resolve your issue and would most likely cause more problems. Yes always a good idea to replace the CMOS. Redo heatsink? I don't think you need to do anything with the heatsink. These processors don't really suffer from overheating, the cooling Synology put in place is more than enough. The DS412+ and DS415+ are indeed very similar when it comes to design, so taking it apart is almost identical. "you did not show which way round the 100ohms resistor goes" Resistors don't have polarity, so it doesn't have a correct or incorrect way. With that said, please don't try to install a resistor on your unit, it won't help you since you don't have the DS415 you have the DS412 and they require different repairs as they fail differently. I am not sure what you searched on KZfaq but I made 3 separate videos on fixing the DS412+ maybe they didn't pop up for you? I don't know which fault or symptoms you have with your unit, but here are the videos showing how to fix the DS412+ Won't connect to the network: kzfaq.info/get/bejne/raifiqxksMfVfqs.htmlsi=2rMzGcpnWoM8shzB Won't Boot failure 1: kzfaq.info/get/bejne/oN19lpZ4v52poqc.htmlsi=Fr7HwWbp_curD4sT Won't boot failure 2: kzfaq.info/get/bejne/rtaGaNyVs8rceJs.htmlsi=f4TL-0luD_rErP3A I hope this helps

You don't need a lot of solder, just enough for the component to make a connection to the board. More solder does not equal a better or stronger bond. If you still have issues with it after rechecking it, you can always send it in for repair. We have a flat rate service listing in the video description.

You are correct that the metal bar is one of the several parts that help hold the case, and maybe it's just a preference, but the way I open it in this video I find it to be easier and safer as it bypasses the need to lift over that bar and opens up the case in 2 steps instead of 1. First, you unlock the shell from the unit and then it becomes much easier to step 2 slide out the shell away from the unit as it's no longer locked in. It could just be that I don't understand how to do the way you are suggesting because I have tried that at first and the issue I always encounter is the amount of force you have to apply is greater since there is a lot of friction between the shell and the other part of the unit. You almost need 3 hands to open up this thing. Luckily in the later versions of their NAS devices, all you need to do is slide it and there is no extra metal bar that locks on the shell.

Thank you! I could not get mine open without first moving that support bar.

Does it not get detected on the network? Try to access it and see if you can do a software update perhaps. If it works with the back plane removed but not with the backplane installed then the backplane could be at fault or the CPU could be having issues communicating with it.

Mhmm, You may have another issue perhaps. I would advise replacing the battery anyways and doing the resistor repair. There is no harm in being proactive with either of those steps.

Wow thank you so much! I appreciate that very much!

I think we used 1/4 watt

I don't remember anymore but it's a Chinese digital microscope. was only a couple hundred but the nice thing is the articulating arm.

Glad it helped

I don't know the answer to that but I assume that it is. It says on the battery what it is. You would have to just check it and then go to the local batteries + or order online.

There is a thanks button bottom right below the video for $tips$. Glad I could help!

Yes, what you are describing sounds like the CMOS battery is the fault. Replace it and you should be good to go. It's less common but it's also possible your power brick could be going out. I have seen capacitors starting to fail inside the power brick before and cause similar symptoms, but in my experience, it's more common to see the CMOS battery cause this issue with this unit.

@@NicksTVRepair thanks for thé answer ! I was hoping an answer but didn't really expect it and so quick !

Lucky timing

1/4 watt or higher will work

@@NicksTVRepair My NAS has revive!!!! thank you man!!!!

glad to hear it

We have a flat rate repair service, which comes with a 1 Year warranty for this repair. All the information is on our website, which I did provide a link in the video description to the repair service page for this unit. If you have any additional questions, our email address is also in the video description as well as a link to our contact form.

Спасибо! Рад, что вам понравилось видео. Так что на самом деле вы тоже правы. Вы можете заменить процессор, и это также устранит неисправность. Но насколько я понимаю, это ремонт, одобренный Synology и Intel, который достаточно хорош для восстановления устройства. Если они говорят, что это хорошо, я им доверяю и скорее просто установлю резистор, так как это намного проще. Надеюсь, мой гугл-переводчик работает нормально. Спасибо за просмотр!

@@NicksTVRepair Hello Nick. Maybe we didn't understand each other. I used exactly your method. Repaired my device. And thank you very much! I am doubly grateful for your attention to my comment and answer in Russian! PS It's just that the repair shop told me that the processor needs to be replaced! But you have shown that it is possible to make easier.

So technically you could also replace the processor to fix it sure and that would be the best way to fix it. But it's a lot easier to do this than replacing the processor, and it also seems like this will add several more years of functionality to the processor without needing to replace it. @@vladimirblagin3105

This is a NAS. NAS stands for Network Attached Storage device. It's essentially a computer that can hold lots of hard drives to store large quantities of data. This one for example is running 4 separate 8TB drives for a total of 32TB of storage. We have a few larger versions of this at our shop for file sharing between computers. Some of the most common uses are for photographers, and video editors, which require lots of data space to store information. We have a few of these for our business and we use it primarily as a shared data storage space that can be accessed by anyone at any computer station in our shop. We have 6 different computers and all sometimes need to access similar data and or info. Instead of paying for cloud storage, we use these. They connect to your network and can easily be accessed by any device connected to the network either by ethernet or wifi. Very useful for most small businesses or home businesses.

There always is a way to avoid melting plastic. Cover whatever plastic you think you might melt with Kapton tape before you do your soldering work. This will protect it and make your work more professional.

@@NicksTVRepair True, I use most of the time this Kapton tape, but, not always it can help.

Try new CMOS first, if that doesn't do it then try the resistor

@@NicksTVRepair Than you! It turns out it was the external power supply. Even though the green LED was on, it had failed. I had another 415+ and I tried its power supply on this unit and it came up....

Wow thanks for sharing this info. I have fixed a lot of these units and while I have seen some of the DS412+ have failed power supplies I had yet seen a DS415+ with a bad power supply. I will make sure to keep an eye out for that moving forward.

@@NicksTVRepair Yeah, and I also tried the bad PS on the working 415+ to make sure it really was the PS and it didn't work on that one either.

yeah that confirms it. That good to know.

I have fixed only a couple of those in the past and all had different faults. The last time we fixed that fault on one of those, there was an IC chip on the back of the daughter board that had the NAND chips on it that was bad and needed to be replaced. I don't have the part number for it and also can't confirm that would be the issue. We have also seen bad RAM cause this or corrupt bios.

Hello Joe, I can't find anything on the DS419 Play, but there is a DS419 Slim which uses SSD's. Those I have not yet worked on and don't have a video for it. Can you send me an email directly, our contact info is in the video description, and if you can provide me pictures of the motherboard, I might be able to help.

Thank you for your response. I will do that asap and email you. Cheers

My apologies for the typo. It's a 415* play NOT 419. I am currently away from the device but will send you images in 7 hrs time

I am not as familiar with that unit. Sorry I don't know if I can help.

Not much to say about it, 100 ohm Resistor 1/4 watt you can get it from hundreds of retailers online or even locally. I bet local shops will have it. You can go higher on the wattage if you want, just not lower.

That should be fine. Either the resistor wasn't installed properly, the trace was damaged, or your processor has failed to the point that this resistor repair won't work and the CPU needs to be replaced. This is something we can do for you. We have a flat rate service for this repair linked in the video description, but the service does not include the replacement of the CPU. If we have to replace the CPU because it's not in a socket but instead is soldered on, it does require significantly more work to perform, and the CPUs are somewhat expensive as well so we usually charge an additional $65 on top of the normal service fee for that repair.

When I power it on I only get the blinking light not the drive or status lights.

Oh I'm very happy to hear. Yeah a lot of the time it can be that simple. Glad you got it working again. If you have more issues with it, I have seen the power supply go out, and if the blue light keeps blinking then an IC chip fails, but that one you will need to send in for repair as it requires advanced soldering.

Yes the lay out is different and the faults are also different as the parts are different in the unit. I don't think it would be a good idea to use this video as a guide to fixing the DS412+ as the repairs are typically vastly different from one another. I do plan on posting videos on the repairs of DS412+ and the DS1512+ soon but it won't be for a few more weeks until after the holidays.

@@NicksTVRepair nick, i send to your email address with my motherboard photo. can you help look ? but my situation same with your .the power led on just blinking . tq

Hey Dennis! This is a Network Attached Storage device. These little guys can actually be very useful for small businesses or even personal use if you have multiple computers in the house or if you have lots of data such as movies. This little guy can hold all of your files, photos, movies, documents and so on and can be accessed by any computer in your office, or home as long as it's connected to the internet. It makes file sharing from your office, to your laptop very easy, or at work from one colleague to another.

Shivasis, One of the reasons we have been trying to show more than just TV repair is because TV repair is getting squeezed a bit. I want to show other repairs that I believe most TV techs should be able to do to expand their business and work. Also, I think these little NAS devices are really cool.
