Have you tried the gyroscopic DeWalt screwdriver? When I am doing repairs I like it a lot, I can control the speed by rotating my wrist slightly. The model I prefer is the DCF680N2. It was a game changer for my bench level work. I in-joy your videos and they helped me with my TS-453 pro. Thank you.
I have not but I am very curious about it. It sounds very interesting that it has a gyroscope. I already own 12 different drills, so I think I need to wait for one to break before I buy more, but I added it to my cart and that will be the next one I get.
Thanks for that great video. I have a TVS-472XT unit, while upgrading the CPU and trying to screw the heat sink back on (with the unit flipped on it side, motherboard faced up), someone distracted me and my philip head screw driver hit the motherboard. I looked carefully and did not see any physical damage on the motherboard or things coming off. When tried to power up the unit, it could not start at all, nothing. I haved confirmed using another motherboard that the cpu I put in was good. You think I might have caused some SMD components to cracked internal (but not visible to naked eye) or that same big BGA chip failed like you showed in the video. What is the name of that chip anyways? Thanks.
Hello Richard, Sorry to hear you are having issues with the unit like that. Unfortunately this is something I wouldn't be able to provide you with any type of information upfront without having the full unit in front of me to diagnose. If I were to speculate, I would say you may have knocked off some SMD components, and sometimes you have to use a microscope to see that, so perhaps you aren't able to see the missing components with the naked eye and need to be using a microscope. Perhaps you didn't knock anything off, but the chip we are replacing and fixing in the video has also failed in your unit. Most often that chip has failed but won't cause any symptoms to your unit until the unit is powered off and back on. Only then does the failure reveal itself. So if the chip is bad, but the unit stays on, you wouldn't know about it until the next power cycle. What often happens is lets say a new update became available. Then you run the update, the unit has to turn off and back on to apply the update but never turns back on. Then you think, oh shoot this update broke the unit. Or you decide to upgrade the processor, obviously you need to power down the unit for this but then it never comes back on. Or a power outage occurs and the unit won't boot back up. Those are all reasons to make it seem like those events had something to do with the failure, when in fact the failure was alrady there the whole time with that defective IC chip, it's just that the failure wasn't going to reveal itself until the next power down and back up. I don't know exactly what that chip is called, I do know it has a name, I just don't remember. If you are looking for the part number on it however, that would be printed on the chip itself.
476 / 5.000 Hi Nick, I'm writing to you from Italy. I have the same problem on my QNAP TVS-871 i7-16Gb with endless booting. I tried to replace the RAM, I carried out the firmware recovery procedure as described on the QNAP site, but I can't even see the AMIBIOS mask. Can you tell me some other checks to carry out. I believe that sending the NAS to your center is very expensive in terms of return shipping. do you have any advice for me ? Thanks in advance .
You could have the same failure as this unit: ruclips.net/video/zShcO8CIkC4/видео.html Add a 100 ohm resistor on your LPC connector as shown in that video
Nice Job ! Could you please make also a video about the error with power delivery of TS453B devices i have not seen anything about that. Thanks for helping and keep them coming !
I have not yet had a chance to work on the TS-453B NAS device but I am willing to bet it is going to have an identical fix to the TS-451+ which I have already made a video about that I will link below: ruclips.net/video/zShcO8CIkC4/видео.html Let me know if that resolves the issue for you, I would be interested in knowing.
Sorry I didn't see your message until now. I don't think we have yet fixed one of those. If you want to send it in, we can take a look at it and give it a shot.
Hello John. We offer a flat rate repair service for this repair which is linked in the video description and in the top pinned comment. I'll copy our website listing link below for your convenience as well. nickselectronics.com/products/tvs-472xt
I have only been doing this repair for about 9 months. So far we have had extremely high success but because it hasn't even been 1 year since we started the repairs, I can't give you a good answer. From what I understand is that as long as you update your unit to the newest software it should NOT be a recurring fault as some of the newer software updates are supposed to take some of the strain off that chip. I don't have any documentation backing this up however, just something I saw someone comment on one of the German forums for Qnap repair.
Why use a 'powertool' for those screws while a decent screwdriver will suffice? Powertools can cause overtightened screws with possible damages associated with it. My advice: ditch the powertool...
If you are only taking apart 1 unit sure thing use a screwdriver. However, when this is your business and have to open and close these units all day every day you will want to use a power tool. The drills we use are specifically chosen because their lowest torque setting is very weak. The lowest setting which is what I use when I put things back together is not strong enough to strip and overtighten plastic screws. It's not a good drill for construction but it's great for electronics. I highly recommend it to anyone working on electronics for that reason.
@@NicksElectronicRepair I can understand, but even then; no power tools for me. The chance you could ruin the screw-thread is ever present. (been there, done that even with the lowest torque available) Using (manual) screwdrivers you can 'feel' the metal working, with powertools you can not. Have been working in electronic repair, best advice I had: never use power-tools. I guess it is a personal choice then.
I still would recommend you give that drill we use a try. As I said the torque level on 1 is low enough to not have any risk of stripping screws. At least not any more than you would hand tightening.
Somebody bought this and return the ram for their own benefit and this customer probably bought that from the defect customer or he or she try to repair it and messed it up
I am not sure I understand what you are saying? Maybe I wasn't very good at explaining the faults in the video but the RAM stick was NOT the problem with the machine, it was however loose in the unit when we got it from the customer. and that means it was rattling around and moving freely around during shipping. When that happened it caused a couple of components to get knocked off the RAM stick. I assume this most likely happened as the customer was trying to troubleshoot their unit before sending it in for repair and may have reseated or tried swaping out RAM thinking it was the fault and when they installed it back in, they didn't put it back correctly. The fault was always the processor chip, the RAM stick just happened to get damaged after most likely.

Hey @@NicksElectronicRepair , I have a TS-456Be if you wanna try to fix it 😁

Looking for some experience. Anyone having such device fixed will the issue appear again in couple of years or it is a reliable log term solution?
