  • In this video we're going to be taking a look at an ASUS wireless gaming router RT-AC86U which I bought from eBay for spares or repair. In the listing it said that they had taken it to the "local repair guy" but he couldn't diagnose the problem. Can we do any better?
    I'm not an expert, but I do enjoy trying to fix things.

    I can see where a microscope certainly comes in handy for the small stuff, the blown chip was a good catch without it. SMDs are my Achilles heel, I've lost more to the floor than actually installed I think. A hot air tool would be my undoing. Great fix bro and probably a really good deal. Thanks for the video and the work, see ya soon.

    5:24. Yes that is indeed a serial port and jtag for testing purpose. Although lots of smart hackery people use those to install alternative firmware on it and its also often the serial port giving access to the bootloader and linux terminal which some people love to mess with (incl me). Some install openwrt firmware on it via the serial port giving full control over the router (because its now your firmware and router) instead of the oem/isp having the control over their oem firmware.

      Then, he learned how to put it all back together. That became taking it apart, repairing it, then putting it back together while reading about electronic and mechanical theory.

  • @chuckbenedict7235
    @chuckbenedict7235 Před měsícem +1

    I have struggled to solder ICs with that kind of package. You'd think they would snap in place, but perhaps it's because of the big pad on the bottom. More flux would seem to be the ticket, but it did not help me. Also having too much solder on the pins and pad will cause bridges that are hard to clear. I've thought of completely cleaning the solder off and using paste instead next time.

    • @BuyitFixit
      @BuyitFixit  Před měsícem +1

      I've done these types of IC before on a power bank and on a Milwaukee brushless multitool on here, not really had too many issues. I think it was the heatsink on the other side drawing heat away also this IC was smaller than the other ICs I replaced in the other items.

    Nice fix. From my time watching TheCod3r, he often pre-tins the pads of QFNs, as they don't consistently wet solder when placing them straight on the board. Might try pre-heating the region as well if it's giving your iron some trouble.

    I feel your pain with that tiny chip. I'm looking at a soundbar just now with an MP1658 that's gone, it's about the size of an SMD capacitor but with six legs... I can see the air turning blue when they show up from China 😂
    I've worked out that it's a 5v supply though, so if I can't get it soldered in I'm just going to bodge in a 7805 and be done with it!

    • @oliverer3
      @oliverer3 Před měsícem +1

      Beware that an 7805 only has half the current capacity of the MP1658 if the soundbar actually needs the full 3A the MP1658 can deliver.
      Assuming a 12V input supply you'd also have to deal with up to 21W of heat dissipation with the 7805 and your input supply would also need to be beefed up to deliver the extra power wasted by the linear regulator.

    • @jasejj
      @jasejj Před měsícem

      @@oliverer3 Yeah all fair points, perhaps one of those LM2596 switching modules would be a better idea. I don't think it needs the full 3A though as it's only supplying the BT chip, the microcontroller and the DAC (the latter two via an AMS1117 3.3v).
      I'll most likely test the whole thing with a lab psu to begin with so I'll know what power it'll consume - I'd estimate a watt or two tops excluding the chip amp (which is fed directly from the 12v supply).
      But hopefully my soldering skills are better than I'm assuming!
      As an aside, it never ceases to amaze me how these tiny little devices can handle such high power... this thing isn't much bigger than a few grains of sand yet can apparently push through 48W (16V at 3A)! I suppose it's little more than an intelligent switch but still...

      ​@jasejj smaller type dc-dc buck converter.. lm2596 tends to be on the noisier side for audo applications in my experience, not sure why because it's supposed to switch above the hearing range. You can get a smaller working regulator set if the frequency is higher, like 1mhz

    This QFN IC has obvious oxidation in its pads (most of the ICs coming from China have this issue due to poor storage/handling/packaging). That's why it was so difficult to set in place. You should tin the pads before you solder.

    • @BuyitFixit
      @BuyitFixit  Před měsícem

      Thanks for that. I wasn't sure about tinning it first. I did spray contact cleaner on it and rubbed it on some paper to clean the contacts and added flux to the bottom. I thought that should be enough. The heat sink which spanned the board on the other side was rather hot so not sure if it was that soaking up the heat.

    I'll have to get myself a hot air tool and try some of those surface mount chips.
    As for your troubles tinning the pads, warming the whole board up a fair bit does help with those ground planes sucking all your iron's heat. Sometimes low-tech tools like a hair dryer can come in handy

    Hello. All your videos are great, as the sign says you can fix anything. I have a Xbox controller that self combusted!!. It was lay on the couch and fortunately it was spotted but only after a plume of acrid smoke emitted from it. The 2 batteries were the standard Duracell AA and were not fresh so perhaps giving out less than 3 volts. It seems impossible this could happen, are you interested in seeing how 3 volts could set something smouldering.

      Depends on what you mean by squeaky noise.
      A high pitched whine could be coil whine or a capacitor resonating. This is usually not a sign of something being damaged but just that silence wasn't a concern during the design stage or cheaper parts where chosen that couldn't run with switching frequencies outside the human hearing range.
      It can be caused by the power supply being overloaded or running at close to its max capacity which in theory could be because of leaky capacitors but I'd consider that unlikely if the device isn't old or it's been dropped from a height significant enough to crack a ceramic cap.

    Okay, let's see what I would have had to do to repair this router lol 🤣
    Congratulations on outbidding me on that gaming router auction, that doesn't happen too often to me, I'm pleased that it was you 👍
    Edit after watching the video:
    Congratulations on a nice fix, that's a small component too. I for one am pleased that you repaired the router and that the hole was not bigger and not over the part number either.

      Yes, this one was a bit of a pain, I did one on a Milwaukee brushless Multi-tool and that one went on straight away, also I think a couple of the power banks I repaired had them too. I think it was the heatsink on the back of the board soaking up the heat. Perhaps I should have removed that and it might have been easier.

    You could use the serial port to flash DDWRT firmware onto that and then you will have a ton of features and a fast access point. I used to do this all the time until Unifi come along and made me lazy!

    • @BuyitFixit

      Yes, I flashed DDWRT on my old ADSL router which was a Plusnet (BT home hub 4). I've already got one of these routers already along with another model and a GT-AC5300 as my main router all meshed up with ethernet cables as we have quite a large house with outbuildings too.

    • @LatitudeSky
      @LatitudeSky Před 29 dny +1

      There is no need to use the port to install third party firmware. You can just download it to the router via the management screen. This model readily accepts DDWRT or MerlinWRT and probably others. All via the IP interface. I suppose you could hack around and use JTAG but it would be purely an exercise for fun rather than required.
