Synology 1815+ won't turn on FIX

[@Sc0t0ma]

Thank you so much! Your very clearly stated instructions just saved me a huge headache and a significant number of my wedding pictures. After my DS1815+ stopped turning on, the jumper method worked for a while, until one day after a power outage, it started remaining in the blue blinking LED stage indefinitely after turning on. For whatever reason, this 1K resister not only restored the use of the power button, but also fixed the blue blink of death I was getting when using the jumper. I really appreciate the effort you put in to documenting this fix!

[@moustange]

Another happy customer! Thank you so much for sharing, Gary.

[@woutvandenberghe]

Thank you so much for this video! This fix saved me more than 1.000€. My DS1815+ was completely dead, even with a new PSU. Glad to find this solution!

Hopefully you can return the power supply for a refund. Glad you got it going.

[@woutvandenberghe]

@ ​​⁠i could send it back. But the old one its fan makes a lot of noise so i will keep it and thus be solid for a longer period.

[@nicodemuscg]

This is great it fixed mine hopefully I'll be able to replace it at some point. I did the Seasonic PSU mod when I first got mine (used) and it worked great until I unhooked it to move it. After that no boot. Tried the 2 psu test from NathanPH's video and still no activity. I did these 2 resistor mods and got it booting again. Thank You Gary what a LEGEND!

Wow thank you! It fixed my DS1815+! the 100ohm resistor was already installed, I just added the 1K resistor and voila!

Gary, thanks for your guide to fix the power issue of the 1815+. I watched this video multiple times, also in frame-by-frame mode around 6:53. But I feel I could not recognize exactly enough where the two wires of that 1 kOhm resistor have to be fixed on the PCB, your soldering points look a bit in the shadow and slightly out of focus here. Could you please add some information on where to put the R exactly? Thanks in advance! Cheers, and a Happy New Year! How can I send you a close-up of my PCB, that I just took? There are these two triple-pad patterns, one is empty, the other carries a transistor. It looks like you place the new 1 k between the 8-o'clock-pads of these two triplets. Correct? Pls confirm or correct. Thanks again.

[@GaryQuiring]

The solder points are well in focus at 5:51.

Hi Gary, great video, thnx and been a Synology user for years, but this 1815+ has nothing more then a headache. Within 3 years it failed and got replaced, but 1 year after replacing, just outside of warranty it failed again of course. So many users have been affected by this. Synology doesnt offer any help or repair options, just a bit of discount on a new unit. I will never buy Synology again! My unit doesn't boot either, 100ohm was already done after first replacement. My power supply is just fine and boots when shorting black and green but the 1K doesnt get the job done. Put a second in series, so 2K, doesnt work either, any idea's?

You will need to replace the transistor, that's my best guess. It's a BC847.

I would wait.

Probably wait as Gary said but perhaps also buy those resistors so you have them on hand if something does go wrong. Also it may help to have a spare ATX power supply on standy for testing and emergency startup.

It's a common issue but those two resistor fixes will resolve the problem. It's very satisfying to fix something like this for under $1 dollar.

[@perfect.stealth]

Hi Gary, thanks for the fix. I just got a beat up Syn server for free, because it doesn't work. From what i've seen (constant blinking orange alert light) the 100ohm resistor should fix that problem.. hopefully. However, it did have another problem too, that the prev owner had a fix applied to it because its powerbutton stopped working. He had it fixed by soldering 2 of the 24-pin together on the backside, to make it work. It does work, but the server starts automatically when plugged into power, and the only way to shut it down is through DSM. Could this be that he used another way of solving the same problem? Or does it sound like a completely different issue? Can you suggest me how to test it? I considered removing the solder and try the 1k resistor fix, but i'd like to hear your take on it before i do anything.

[@perfect.stealth]

It seems another one had the same issue and i found (hopefully again) the fix in your conversation.

[@GaryQuiring]

Soldering two wires from the 24 pin connector is proof that the transistor is the issue. Applying the 1k resister to those two solder pads shown in the video will/should solve the issue. Make sure to remove the connection on the 24 pin connector though.

[@perfect.stealth]

@@GaryQuiring Thanks for the quick reply! Yeah i will remove it, and hopefully get a fresh NAS out of it for "free" :D (just had to buy all the hardware lol, i'm new to the whole soldering thing) The description the other guy had fits mine 100% (green and black soldered together), however the resister fix didn't work for him. He had to replace the transistor from what i understand. Did i misunderstand something? - again i am completely new to this, so sorry in advance for asking stupid questions.

[@GaryQuiring]

@@perfect.stealth It's true that eventually the transistor could totally fail and need to be replaced. Sometimes installing a higher K resistor can fix it too. For now I prefer the resistor fix, replacing that small SMD is difficult.

[@stressballer]

Hello and thanks for this video - I have the same problem with my NAS just now. I was just wondering where or how you found out about this resistor fix? Why 1k ohm resistor and why the two contact points as described in your video? Any other resistor specs I should know about? Is this a better fix than swapping the transistor? Do I have to do both? I guess I need to go get myself a resistor. Thanks!

[@GaryQuiring]

Because the transistor is surface mount, it's harder to replace. Many including myself have resistors in their electronic junk box and are able to fix this NAS the same day it fails. You can replace the transistor to fix it and that new transistor will fail again. Why 1k, it's what I read works but I am sure other OHM's within reason will equally pull down the transistor so it turns on the NAS.

[@GaryQuiring]

You have to add the 100 ohm resistor for the Atom bug fix. Do that while it's apart, it will also prevent the NAS from working if that fails. That's an Intel bug. The 1k can be added or you can replace the transistor, either will fix it.

[@JulienDigoit]

Hi Gary, thanks a lot for your video. One of my DS1815+ suddenly stopped working and won't turn on anymore. I wanted to ask you if I should also test the power supply unit? Atom bug fix isn't applied on the server at the moment. Thank you.

[@GaryQuiring]

It's most likely not the power supply. Do both resistor fixes.

[@nicolae.cristoloveanu9912]

Heya Garry greetings from the UK. Awesome video by the way, I fix alot of stuff too. Got a DS1515+ that worked for a while but it stopped working recently, I was assuming it could have been the power supply but now watching your insightful video I am wondering if mine has the same problem? Is there any way to check, thank you in advance subscribed looking forward to more videos!

[@GaryQuiring]

More than likely it's the same thing, I did a quick search on KZbin and from what I can see the motherboard looks very similar. It could be the Atom bug or the transistor. I recommend doing both. You could also short a pin on the power supply connector between any black wire and the green (there should only be one green wire, if not do not do this). The short should turn the system on, if it turns on you know it's the transistor issue.

[@stanbriddes2993]

Hi Gary, thanks for the video, could yu tell me the wattage of the resistor you used. Thanks, Stan

[@GaryQuiring]

1/4 watt

[@ahndeux]

I just checked my server and it was offline. I went to the box and it was dead cold. No lights, nothing. I thought it was the battery backup system acting up, but sure enough the 120V was on the line so its something in the box. The box already had the resistor fix for the CPU so I knew that wasn't the problem. Took it apart and the power supply checked out fine on my tester. So its not power supply. This is when I started to get worried that its a major fix. I checked the youtube videos and other people with 1515+ units had similar issues and showed the jumper setting to check out the transistor. I bridged the Q4 transistor and sure enough it came to life for a brief second. AHA! At least now I'm not turning green wondering if my server is permanently down. I took the motherboard out as shown in this video and looked at the transistor on a microscope. The letters read "1AM" and the letter "F" sideways. I looked up the spec and it turns out to be a MMBT3904 NPN transistor. I don't have one of those lying around so check my stock. Hey, I got a MMBT2222A NPN transistor. I wonder if that would work? I checked the specs and the pinouts are identical. The only difference is the collector current is 200mA on the 2N3904 and 600mA on the 2N2222. Close enough for government work! The 2N2222 is marked as "1P" on the transistor body for those who are looking for similar parts. If you have old PC boards with SMT parts, they are all over the place. Just check out the markings to make sure you have the right parts. FETs also use the same SOT23 style package. I fired up the hot air rework station to 350C and put that nozzle right on the part. Two minutes go by, nothing. Hmm... Cranked it up to 400C and tried again. Nothing. Crank it up to 450C and heat that part. Still not flowing! Crank up the air flow higher and its still not coming off. The motherboard is heat sinking too fast to even melt the part. I started to smell plastic burning and realized the connector next to Q4 was getting singed. Ack! Plan B. Fired up the soldering iron and hit the part with the soldering iron instead. Its not melting!! Arg.. The damn solder they use is very high temp solder. I added some 60/40 tin led solder and the part came off immediately. Good old tin lead solder to the rescue!! Took the part off and cleaned the solder pads with solder wick so its nice and shiny. Slapped in the new part and soldered it in place. Cleaned up the flux with some good old isopropyl alcohol and looks good as new. Put everything back in and did a test run. Hey!!! Its starting again! It's ALIVE! Yay!! Put all the parts back together and fired it up. Its purring like a kitten. Now I can access all my bootleg... errr.. legit movies that was "backed up". Time to dim the lights and get out the lotion.... Thanks for your help! It worked out great. Saved my day!

[@mriswith23]

I applied both fixes and I still could not use the power button. It was able to boot after I jumpered the green wire of the power supply to the black ground next to it. Previously when I tried the jumper boot I got the amber alert and power flash non-boot issue. At least the 100 ohm is working. I'm pretty sure the 1K was secured well. Am I missing something?

[@GaryQuiring]

The transistor (Q4) is probably toast. You will need to replace it. It's a BC847 which Amazon sells. I replaced one just two weeks ago. My 1815+ that I did the 1k fix on about 3 years ago had the same issue, it would no longer turn on. Shorting the green and black on the power proved it was working. Once I replaced the transistor it booted but it still required the 1k resistor which surprised me. The root cause of the problem from what I have researched is an out spec voltage coming from the power supply. I replaced a resistor in the power supply last week but there is no way to know for sure if that will permanently fix the problem. I was planning on making a video on how to change out that resistor, it's not easy. It's very tiny, SMD type. For now get that BC847 replaced, that should give you several years of service.

[@digitconnl]

Hi Gary, thanks for this video. I am going to try and fix my DS1815+. I also broke the flat cable that shows in this video, do you know what type of cable this is ? or where i can order an replacement cable ?

[@GaryQuiring]

The ribbon cable is most likely not custom, it's probably easy enough to find. Count how many pins across it goes and search for it with Google. Make sure the edge connector looks the same, they usually use the same spacing.

[@dekm9881]

Have you encountered a power problem where the power adapter turns on (green LED turns ON) when plugged into the wall outlet but when plugged into the Synology DS720+ the green LED light indicator turns OFF immediately? The DS720+ would not even turned ON when the power button is pressed. Thank you.

[@MaxPaws]

Mine just failed after 7+ years… Ugh. 😢 Is there a detailed vid on the installation of the resistor you didn’t have to change? From this vid, it’s apparent that the unit can still fail even with the “first” resistor replaced. It seems slightly easier to do, so I think I’d like to try that fix first.

@@chriswright3327 The 100 ohm resistor is an Intel bug with some of their Atom 2xxx CPU's. It's not related to the 1k resistor fix.

It was not common knowledge back then about the 1k fix. I found the discussion on a German forum and decided to try it. The 1k fix is because the transistor (BC847) fails which prevents the system from turning on. A lot of the Synology motherboards have the same design with the transistor they label as Q4. Since yours is turning on most likely the Atom fix is all you need.

So increasing the resistance might help? Then I'll put it another 1K-ohm in series with the current one.

@@Tokkevo Surface mount components are harder to solder but if you get a magnifier loop with one of those goose necks on it with a LED lamp it's not that bad. I built a couple of surface mount kits this past year and have finally gotten the hang of it. You will also need a bottle of liquid flux. Here is video that shows my LED project. kzbin.info/www/bejne/qYLFqqGbmbmhhtk

@@GaryQuiring Hi Gary, thanks again for the tips! Measuring the voltages on the green and black wire made me realize that the transistor was not doing anything when pressing the powerbutton. So replacing the transistor did the job (I actually just placed a new one on the empty Q1-area and left the broken transistor in place on the Q4-area, since I didn't want to fiddle around too much on that small area) So thanks again for your help!

[@GaryQuiring]

@@Tokkevo That's good to know we can use the empty Q1 area to use a transistor. I'm assuming at some point the transistor will probably fail with these resister patches. It might be time to consider just adding the transistor instead. What transistor did you add to the Q1?

Hi. I had the same blinking light issue and applied both fixes which fixed it until a manual power down and the device won’t power up anymore. Any suggestions? Tried another power pc supply and shorting the two pins but no luck.

[@GaryQuiring]

If shorting the green to black wires on the power supply does not turn it on then something else is wrong.

[@baljitbasra8671]

@@GaryQuiring could it be the resistor has gone bad?

[@GaryQuiring]

@@baljitbasra8671 If shorting the green to black wires on the power supply does not turn it on then something else is the issue. No idea what that could be though.

Thanks, got two dead units up and going a gain ..

Hey, mine also has one DS1815+ nas library, and recently it happens suddenly auto shutdown after powering up for a capable minute, would this also be because of the atmos or the resistor faulty?.

[@GaryQuiring]

Either could cause the issue, add both resistors and you should be good.

[@jvmkite]

Hello, I have a much older NAS, DS1010+ That was working until 2 days ago. Now the same issue as yours had, press power button, but nothing happens. Could it be the same issue on this old motherboard?

[@GaryQuiring]

Not sure, easiest way to find out if the power supply is actually working is to short the Green and black wires on the power supply together with something like a paper clip. If it powers on then it's that transistor. There should be only one green wire on the connector. You could research that for more info.

[@jvmkite]

Thank you@@GaryQuiring for your comment. Apparently, in my case, the problem is the power supply. I used a normal ATX one and the NAS Boot. thank you again for your comment, it made me suspect/test that green/black wiring to know if it was working.

[@dawsonsg]

@@GaryQuiring Hi Gary, which green and black wires? I dont suppose you have a photo do you?

[@aaronbishoff8695]

any chance you can fix mine for me?

[@GaryQuiring]

I won't take on the responsibility. Plus shipping is crazy expensive these days. If you don't know how to solder find a local person who does.

[@aaronbishoff8695]

@@GaryQuiring ya I called a bunch on local shops. Not finding anyone yet.

[@GaryQuiring]

@@aaronbishoff8695 Co-workers? Facebook friends? Someone must know how to solder locally.

[@JBEAS1980]

That did not work to get mine powered up. Shorting the green and black wires does. Also mine is 100% factory and I have owned it since new and it had the atom fix from the factory.

Hi, what type (model number) of the 1k resistor is good for the transistor fix? Thanks!

[@GaryQuiring]

1/4 watt 1k will work fine

[@nemolusl]

@@GaryQuiring Thanks Gary, just to confirm, does something like "Metal Film Resistors - Through Hole 1/4watt 1Kohms 1%" look good?

[@GaryQuiring]

It can be a carbon type too, no need to pay more for the metal film. 1, 5 or 10% is fine.

[@nemolusl]

@@GaryQuiring Thank you so much!

I've got a dead 1815+ synology, did the atom bug fix. My CMOS battery holder broke down and replaced it with a CR1220 PC battery (yellow plastic thing with red and black wire soldered it to the old CMOS battery case. changed the power supply with a new one. It turns on but the orange status light is blinking and after half minute of time the nas shuts down. I've searched the internet but found no solution. Any tips?

[@GaryQuiring]

Did you solder the resister over the transistor like the video shows?

[@tomasdigneffe]

@@GaryQuiring Dit that. stays on now, orange status led keeps blinking. Already did a reset. And now installing an update on the DSM. THANKS for the trigger to solder also the resister!

[@kublermdk]

Ohh I think I have this exact issue! I just turned off my Synology nicely and suddenly it won't boot up again 😞

[@MrWizz220]

The reason Synology will not do this is because of greed. They want you to buy a new Diskstation.

[@StevenAndrews]

Well the USED to be around $200 on ebay... ;)

[@francescn.6919]

Another example of programmed obsolescence.

[@deezknuts07]

Mine just caught the blinking blue light of death. I don't have either fix in but will try the 100ohm and 1k ohm fix and see if it works.
