However, respectively you do not have esd protection on those USB lines. Static build up on the USB connector can pass through and cause logic board faults / damage.

    2) the 0201 esd diodes are very common and simple to source.

    Here is an example of many:

    3) you will need a good pair of tweezers, flux and low air pressure hot air tool to replace these tiny parts.

    4) which xbox esd part cannot be found? TVS ESD parts are quite common and should be easy to source. We typically purchase direct from the manufacturer for our OEM designs. Share more details on the xbox part.

    5) if the usb type c connector is suspected then the paddle board should be replaced. They are very common in AliExpress. Search for your model "Axxx USB type C". Usually under $5 USD each.

    6) can you post clear zoomed up pics of the area you suspect?

    Will read and study the rest of your post when fully awake..
    Thanks.

    1: 2: & 5: I might send you a pm see if I can put in a order for the esd diodes, and regular diodes. By “paddle board” I assume you mean the ribbon with the male twin USB c connectors? Do you stock the paddle board and the board side connector or do I have to go to Ali express for those? The paddle board seems fine, it's the board connector which is mangled. I've linked some pics below.

    3: Which tweezers do you stock? I've been looking for something like these Albert heists h 6015. There hook tweezers but they also have a 90 degree bent tip upwards so you have a small see-saw to press against the board helps with my shaking. But I haven't been able to find anything locally, I can only find them from EU and they want $350 for them. Ali express had something similar but didn't want to wait 2 months for them.

    4: I believe it's the Xbox one X and Xbox one series X (both use the same part) HDMI ESD protection diodes. The cod3r on YouTube is always complaining about not being able to buy them and having to use donor boards.

    6: I'll upload a few pics and link them. For some reason imbedding them does not work for me.

      Hi. Sorry for not being clear.

      Check out Arrow.com - if they stock the part, only then it may be practical for us to drop ship the part directly to you. With our account, we believe we have international free shipping based on our volumes of purchasing. We would like to test this with you (or others).

      For the tweezers, they do have a kit of 3 of them for about $12 USD. Again, the shipping with Arrow should be free and is with Fedex so you will receive the goods quickly. Just need to watch any local customs charges if the $$ is too much. You may have some local taxes / import duties(?) but check before you proceed. You do not need medical tweezers for this 'operation' (my idea of a joke).

      For the USB C paddle board, you must work with Aliexpress:

      https://www.aliexpress.com/item/1005...79921736%22%7D

      is one of many vendors selling the "A1992 DC Power Jack".

      Here are others:

      https://www.aliexpress.com/wholesale...psort=1&page=1

      Tweezers from Arrow.com:

      https://www.arrow.com/en/products/pis-0971/pi-supply

      So in summary, shop on Arrow.com and if it is practical - we can try this drop ship idea. Otherwise I know that without our account, shipping is crazy high with Fedex. For example, here in Canada - the shipping alone is $50-$90 USD for overnight shipping. It is waived with our account status.


      Tweezers on Aliexpress (there are many out there):

      https://www.aliexpress.com/item/1005...79309322%22%7D

      At the very least, very practical for us to source the ESD TVS diodes (0201, etc.) from Arrow. They are the largest in the industry for electronic parts. You can send a PM when ready or continue to post the details of what may be damaged on your logic board.

      Update - have zero knowledge on X box but found the youtube video - is it U21 ? Microsoft is large enough to have custom parts built.

      ST does offer other similar looking / similar function devices:

      https://www.st.com/en/emi-filtering-...mi2c4-5f2.html

      Posted the same on the youtube video. Perhaps someone else can compare the pinout to see if it is a valid fit.

        Thanks I’ll have a look and get back to you. Going to try see if I can find some donor boards of Ali express first so I can get other parts needed as well. I’m suspecting the CD 3217 (u3100) is probably faulty but that said both of them have the exact same diode mode measurements of 0.68.
