    Dead xbox one controller - 1ACMD short

    Hi,

    So I'm trying to repair this xbox one controller, and I found the the 3.3v regulator is shorted. The number on it reads 1ACMD, I cant find a replacement anywhere.

    I was hoping maybe someone on here could suggest a suitable replacement, in the UK preferably.

    Thanks in advance!

            There is some reference here to a possible substitute http://forums.xbox-scene.com/index.p...and-info-1537/

              That's where I got the pic from, I read about the MP3414, but I wasn't able to find a source in the UK

                the spec sheet says this ic converts 1.8 volts in to 3.3 volts output

                    Thanks for the links guys, as far as I know, mouser ships from USA. So I will probably go with rs-online.

                    Do you think that one will be suitable? I usually replace components with the same ones, I don't have a clue when it comes too substitutes.

                      Hello. Have you fixed your issue? I just got one in today with the same problem. The datasheet and part number you have is incorrect. This is the part number: mp2161gj. It should convert the incomming 5v to a voltage Microsoft predefines, with two resistors, as you can see in the datasheet. I have measured the resistances, made calculations, and output should be between 3 and 3.3v.

                        I did resolve the issue, but I used a donor board in the end.

                          Short circuit on XBOX controller - Model 1914.
                          by MarkC1970
                          We have a XBOX 1914 controller that has shorted the 3V3 to J2 (aerial connector). If you unplug the aerial, the controller boots and connects. It seems stable without the aerial plugged in but it is not ideal.

                          The schematic is on https://www.acidmods.com/RDC/XB1/Sch...OME_VALUES.pdf

                          I have little to no understanding of these RF transmitters and so I am unsure what has failed. Currently, T2 is short on Pins 1 to 2 and RFF2 is also short on Pins 1 to 2. This is how the 3V3 is getting connected to J2, clearly one or both of these components are faulty....

                          Xbox One S - 12V Rail Short - Q9F1 Keeps Blowing
                          by grimacelord
                          Hello,

                          Have an Xbox One S here that has a short on the 12V power rail. There is no power, beep, or partial fan spin when connecting power cable.

                          After diagnosing with thermal camera, Q9F1 MOSFET (NTTFS4C50N) is getting hot. When I remove this MOSFET, the short on the 12V rail disappears.

                          I first replaced Q9F1 with one from a donor board and then partially reassembled the Xbox to test. When I plugged the power cord in, I got a partial fan spin and I thought I had fixed it, but unfortunately, the Xbox still did not power on. So I then disassembled the Xbox...

                          Transformer replacement for a dead coffee machine
                          by double_DD
                          Hi guys,

                          I have a dead coffee machine, and it seems that the culprit (no 1, at least) is a dead trafo - primary coil seems to be blown open (type shown on the picture below).

                          Now, I'm unable to find direct replacement anywhere on ebay or aliexpress, and all similar that I' was able to find are rated too low (<1A).

                          If someone knows a shop to buy replacement (EU/CH), that would of course be my 1st option.
                          My other ideas:
                          - to buy 220/20Vac trafo with 30VA, and to "manually" create secondary 12V output just via resistor
                          - to buy...

                          Finding a dead short component
                          by Beton
                          Hi guys!
                          I searched for the term "dead short" in the forum but no specific thread came up however if I'm just blind and couldn't see the thread talking about this please forward me to that direction.
                          So my problem is I don't know how to find the source of a dead shorted voltage rail. Dead short = ~0 ohm resistance.
                          I have two VGAs (HD 4850 and HD 4870), both dead shorted to ground on the memory rail. I have the boardview file for the 4870 and the memory rail consists around ~7892346 capacitors...
                          I have a bench PSU and if I try to inject voltage the voltage...

                          Gigabyte GTX1080 - identifying a dead short on vmem
                          by Prott
                          Hey!
                          I have a problem with Gigabyte Aorus 1080. The card seems fine (expected resistance on vcore, pex, 5v, 1.8v, 12v and reset) except for a dead short on vmem (FBVDD). It's interesting failure mode, cause usually (in my experience) when memory fails it still retains a few ohms - this one is literally a dead short.

                          I removed the inductors and tried inject voltage (0.8 V at 6 A) which only seemed to warm up the cables to the card while the card itself didn't show any hotspots.

                          Is there any way to narrow down the search for a short? I would prefer not to remove...
