    Hello

    I bought an occasional flooded Xbox One

    The console does not turn on, it is in the STANDBY mode all the time (orange LED on the power supply)
    From what I initially noticed, the 5v voltage is disappearing somewhere.

    According to this diagram, wherever 5v should be, I have 0.4v. There is 5.2v correctly on the power socket.
    I have a couple of suspicious looking resistors in which when I check the resistance it keeps growing until the scale ends. on other similar resistors (is it a resistor at all?) I have a constant resistance.

    Any tips where to look? It is possible that what I call a resistor (marked in red in the pictures) is not one at all. I repair phones on a daily basis and for the first time I do something like that, so please bear with me ;)

    Since you repair phones, you should know that the selected element is a regular capacitor :)

    Do you repair phones? By replacing the digitizer, battery, I guess ...
    No offense, you would tell a capacitor from a resistor I guess. Because what you selected is a capacitor, I would rather not bet on a flood-damaged one.
    You have a schematic of this Xbox? Because it's gonna be hard to find without where it goes.

    So yes, I did a few more measurements and the 3.3v voltage is also dying and I found a place.

    Designation B2L RC40 (Diode?). 3.6v on the one hand, 0.4v on the other. Rises to 1.2v when heated, and drops to 0.4v when heated

    looks like a schotky led

    After all, there is a clear symbol next to it. Diode. Do not heat up, just desolder and measure. @Jawi_P clearly wrote: SCHEME.

    Well, it's a schottky diode. But I do not know which one to buy because according to the markings that are on it, nothing can be found. The Chinese have clearly used tin here, which I don't want to melt too well. Hotair does not move it, buttstock at 400 degrees barely, barely ....

    Unfortunately, I have not found the diagram anywhere

    Go to the site with it.

    If I wanted to, I would take it to the site, but that's not the point.

    Mosfet SI4501BDY died (no 5v voltage at the outputs, the input is as it should be) and the diodes are BAT54HT1G. Diodes are available in Poland, worse with mosfet ... only on aliexpress.

    What a difference what the diode originally sits there. You put another SMD in this case, you should find 3A without hassle.
    Besides, if a diode went off and then you found a mosfet down, I don't think it will stop there.

    I ordered 2 pcs of mosfets. I'm waiting for the package. The diode is replaced on days, after this treatment the 3.3v line should be ok, I will still check. I just don't know how to unsolder this damn thing. The easiest way would be hot air, but it's probably lead-free tin and I don't want to move it: / I think I have to buy a thicker buttstock tip and try.

    Water it with ordinary tin, heat it up with a soldering iron and try to suck it up, maybe it will let go.

    Add lead-free tin, suck with a tape, sucker if necessary, add lead-free again and the hotair should go.
    As you start to pry and heat on one side, you tear off the pads. The stock itself is hard, I sometimes use two at the same time.
    There are even special tongs that are heated like a double flask.
    Although the hotair itself should go for you, unless yours does not give the temperature it should.

    So I will. The console was flooded from underneath with orange juice :) which is like standing in a puddle. There must have been a short circuit on the other side of the plate because there are no signs of flooding at the top. I washed everything with isopropanol, I hope it will be ok. I will not start the console until all the voltages are in line with the standby. Later I will see what happens when the power supply releases the + 12v lines if it ever happens ;)

    Hello, I found the topic to connect, I can not locate the power points of the two pins where, according to the first picture, it should be 3.3 V. Exactly these two pins marked in the picture. One of them just breaks off and goes nowhere. Flooded Xbox One Console: Analyzing Standby Mode, Orange LED, Voltage Drop & Suspicious Resistors

Topic summary

The discussion revolves around a flooded Xbox One console that remains in standby mode, indicated by an orange LED on the power supply. The user reports a significant voltage drop, specifically noting that the expected 5V is only 0.4V in certain areas. Participants identify a component mistakenly referred to as a resistor, which is actually a capacitor, and discuss the implications of flood damage on the console's circuitry. The user discovers a malfunctioning MOSFET (SI4501BDY) and diodes (BAT54HT1G) and seeks advice on replacing these components. Various methods for desoldering and replacing the damaged parts are suggested, including the use of hot air and lead-free solder techniques. The user plans to ensure all voltages are correct before powering the console back on.
