You are a hero! I thought I had just lost my data on my TS251+. Your fix saved the day. But as you mentioned in the video, it remains to be seen how long this fix will last. Nevertheless, it should be a lesson to me to make backups more often. THANK YOU. 😄

Many thanks to people like you making it possible to deal with such failures and problems. My TS-251+ died at night and is now back among the living.

One tip for not having to reassemble everything, just put the HDD tray on bottom (heavy) then the mainboard upside down on top, plug in fan, plug in cables and run it to copy all your volumes. This way you get good cooling and won't risk busting the resistor if it can remain out in the open.

Man, I was able to purchase this in 2022 and still got this problem!

Success on TS-251+ - So glad I found this & the supplemental pin-out/close up video! Lost the encryption key in a pc failure several years ago & didn't know it until I tried to move the drives to another QNAP. This helped me recover years and years irreplaceable of CAD drawings. I cannot thank you enough for making these videos!

Your video fixed my 451+, Thank you! I was prepared to connect a jumper with DuPont connectors and was disappointed to find there is not enough room provided. Soldering directly to the pins, a 100 ohm resistor to ground worked right off the bat. It took me less than an hour and most of that time was dismantling and reassembling the unit. I'm not sure but I don't think there was a single screw left in the box. Thx again, Bob

This worked for me! Saw the same signal on the scope. Soldered a 100 ohm resistor between two female pin connectors and jumpered pin 1 to ground with it. Everything came back. I will retire the unit and replace it - but still a big help.

It works for my TS-251+, but the voltage still low(1.36v), so I usu a 150ohm to let it become to 1.67v

One more person this worked for. TS-251+, gave up after 7 years. Thank you! Allows me to move things to a new NAS.

It worked!! I've just fixed my TS251. Thank you for investigating it and taking the time to record this video and publishing it to the world. I have plans to replace my qnap with something different. This fix has allowed me to have the very last version of data.

Tengo una palmtop 200 LX ,Hewlett Packard. La pantalla se ve como derretida en un sitio,es factible su arreglo?gracias

Tiene algun link de compra para esta calculadora

This method works great, thanks for saving my TS-451 :-)

Μπράβο σε ευχαριστούμε

Great Video! Is there any way I can get the STL 3D files for the chain guard mount? Also do you have the link of the exact bafang model with options you ordered?

I fixed the issue! Thanks a lot!

One more dead QNAP NAS TS-251+ revived! Now running without any problem! Thanks a lot!

I revived my TS-251 with this resistor fix last year (maybe even two years ago) and it's been working great, but recently (last month or so) it started rebooting itself or sometimes just stuck powering on and right off after a few seconds, but sometimes it just starts up and it works fine for maybe a day or two and it again loops.... I just took it apart to see if the resistor was still in place properly and it seems so... what can be the problem? maybe it needs a different resistance now that some time has passed on it, or maybe a power issue (I checked the brick with a voltimeter and it seems fine)

Great advise. 100 Ohm (0.5w) resistor between Pin 1 and 8 using jumper shunts and got my TS-251+ back up and running today. Cost me less than AU$5. Thanks guys !!!

many thanks - it works fine for my TS 251+

What value can I use?What resistance value can be used

Good evening, I tried the method and it worked, but after restarting it it stopped again. What is the solution?

Thank you

Hi, cannot find your part 2

Buyer beware indeed. Thanks a mill, this fix works on my TS-251+ but I still find it a bit surreal.

Absolut Legend, this fixed my Qnap

new repair tip - after using the nas with solution from this video (resistor direct soldered on pins) for a while it stopped working - I have few hours played with that - and have researched - that when cabled out to breadboard for splitting the signal for oscilloscope and quick resistor change - it works every time. also that has lead to probe the resistor soldered with double breadboard wire addon - which was not working - but when the wires were apart it has again begun to work - also the solution is - solder the resistor on each side on single breadboard wire (cover with heat shrinkable tube to protect agains shorts) and lead the wire with resistor included like one string around the nas motherboard - from one ground pin outgoing, under the board, to other side incoming to the clock pin - IT WORKS AGAIN ! :-) (please, who can explain ? what does the additional wire ? what it act like ? a capacitor ? a magnetic field capacitor ? or what ? because of the fact that when the wires are together, it doesn't work... the frequency must play a role there...)

Can you post a video of how to solder it in? I have a 251 with the same errors. Maybe a link to the 100ohm resistor that everyone got.

Thanks for this awesome teardown video. I have 48SX back in college year in the 90s, the LCD getting darker with first icon row "burntmark or bleed" . It could be due to aging or humidity. Will dehumidifier or dry camera cabinet help to improve the LCD screen? I could still see the screen, but at brighter room. Not sure if I need to use plastic plier to open this unit to clean the PCB with 99% isopropyl alcohol . Oh, one of the bottom battery twin- terminal has been loosen , I may need to glue it to the pad. Thanks again

You change baterry and motor 🤔

another me too comment. Mine was purchased in 2016 and died this morning. I only had two 220ohm resistors in house, so I put them in parallel. Worked great. QUestion to @powerevolutions... It's been three years since you fixed yours. Is it still going? Any suggestions on a replacement that won't have the same issue?

Just an Important WARNING for those who have managed to fix their QNAP NAS by adding the resistor. This fix is TEMPORARY as the silicon in the faulty chip will Continue to Degrade over time until the failure becomes Permanent! This fix should give you enough time to order a replacement (I got the 464) and migrate the old disks to the new NAS box. NOW the only remaining question is: did Intel FIX the problem with the clock hardware, or will my 464 also be subject to the same defect as the 451??

My TS-451+ just died. Internet search found this and some other videos about the 100 Ohm fix I soldered in a 100 Ohm resistor and my 10 year old 451+ came back to life. No data lost. But now I have to wonder how long before the thing finally dies. I really do NOT want another QNAP NAS with unreliable intel components - but the AMD stuff is 2X the cost.

So THAT's why some people try to pawn these off for stupid money with a rubber band around them. Not sure why anyone these days buys a used calculator for more than $20 in the first place.... we all carry one on us all the time.

Can you tell which CPU you have? I've read Intel fixed this with Stepping D1 on the J1900 but I haven't found any info on what that looks like with CPUINFO. This is what mines shows model name : Intel(R) Celeron(R) CPU J1900 @ 1.99GHz stepping : 9 microcode : 0x90a

Thanks for this video!! Had this issue two days ago with my 453 Pro, now awaiting resistor to arrive and then start sweating to get the fix in (hopefully)

Hi, this solution has partially worked for me… I used a 100ohm 1/4w resistor on pin 1/8. Now the nas boot (451+) but two leds are still red.. first two before the power button… there are other things that I can do? Just to be clear, I’m able to boot the nas and I see the user interface with hdmi connection (the boot time is quite long… around 8 minutes…) but two leds before the power button remain red…

Thanks for this Mr. powerevolutions! It helped so much. Another QNAP connected and being backed up!!

Thank you, you and your resistance make my day ! My Ts-451+ is back on track :)

I took the batteries out discharged the capacitor and reset it. Thank heavens it works.

Mine in a Bedside lamp just went. Under a magnifier I see the cracks. Printed on the base says "Suitable for damp locations". HA. These LED bulbs do last a long time though. I try to remember to write the date of installation on them with a Sharpie just for my information when replacement is needed. I failed to with this one. It gives a rough idea how good a bulb is.

Hi! What kind of conversion kit did you use? Thanks.

Thanks for your excellent video. I really appreciate that you put the 'scope on the pins so we can see the effect. My TS-451+ crapped out yesterday (I thought it was due to the eclipse - it wasn't lol). I didn't have a 100R resistor available, so I used a 150R, and that didn't work. I had a 1K trimmer available, which I adjusted to 100R, and my NAS is back in action! While I had the PCB out, I changed the battery and upgraded the RAM, so I'm hoping it will be good for a while. Thank you!

I had 2.2v so I did this (100 ohm pins 1 - 8) & all AOK but for how long is anyone's guess. Was thinking of upgrading anyway so that's where I'll be heading next. 😁

Soo many thanks for making this video! Fixed my TS-453 pro.

Fantastic video. I just fixed two TS-453Pro units this way. It's super easy on that model, no need to disassemble further than taking the cover off. Thank you!

fixed my 453Pro :) Thanks
