TP-Link HS110 Disassembly

Introduction

My own TP-Link HS110 malfunctioned right after the warranty expired. (within a week…) So I decided to fix it myself. I was able to find a way to disassemble it non-destructively, but I wasn’t able to fix it yet.

It keeps turning itself on and off, showing it is not connected to the Wi-Fi. Pressing any button on it won’t fix it. If you happen to be a competent human being, I would love to get some guidance about fixing the internals.

What you need

    • Keep in mind, that following this guide will void your warranty! Even the first step!

    • There is 1 screw that holds the cover plate in place. In order to open the housing you have to remove that screw.

    • The screw is hiding under the sticker. You can try to remove the whole sticker. I just scratched through with the spudger to expose the screw. (This voids your warranty!)

    • Remove the screw. I used a PH0 screw bit.

    • To remove the cover plate I used the metal spudger.

    • Start on the bottom of the plate. There is a little gap right above the Reset Connection button. The spudger fits perfectly in that little gap and you can pop the first clamps out by stretching it.

    • I think this was the key for the whole process.

    • After that, just go around with the spudger and pop all the clamps out one by one.

    • Finally, the internals are exposed. But be careful, it is very easy to break the whole circuitry!

    • There are 2 main PCBs inside on top of each other. Those are connected via a soldered mini "bus" PCB. The bottom one is screwed into the backplate via 2 little screws. You have to remove those to get the whole thing out without breaking it.

    • Unfortunately, the screwdriver in the Pro Tech Tool Kit did not fit into the small gap which leads to the screws. So I had to improvise with a small form factor screwdriver from a random HDD kit.

    • After removing the 2 little screws, you can pop the whole thing out from the housing.

    • If your device has the same malfunction as mine and you managed to fix it, please reach out to me, so I can have my smart plug back in business! Thanks!

To repair the device, you must replace the capacitor C4 = 470 mf 16V that you see on the back of the the red arrow on step 5.

If you check, it have a bulge on the top, on my device happened the same, now it works.

Hello, I also have a problem with this equipment. Unlike you, I have a good WIFI connection and it doesn't switch off unexpectedly. However, when I press the switch or turn it off via the app, the power still flows. I think it could be the relay but I'm not sure. Do you think this could be the cause? How can I test it? Thanks
