    Xbox Series X - Instant Off (2s) SP (2): 0007 [SP_RAM_SHUTDOWN]

    It's the chip marked "I" on the picture. Has to be replaced with the same model/RAM taken from a donor board (from the same place). Doesn't guarantee that it will solve your issue, because the error can also be caused by missing or bad components (like resistors, capacitors) around that module...

    Xbox Series X - Instant Off (2s) SP (2): 0007 [SP_RAM_SHUTDOWN]

    it's exactly what it says, RAM chip failure. You have to look at the code before 0007, which is 9908, and 08 is the RAM chip that reporting an issue

    J20H104 instead of AW-XM501?

    yes, can use J20H104 instead

    Xbox series x don´t power on

    get Series X schematic, it's floating on the web, that will show you where all the power rails are, and the chips that generate them. Once you get all your standby rails up and running, use Pico to pinpoint the issue, nobody can't help beyond that

    Xbox series x don´t power on

    possibly Southbridge IC is damaged, i would check resistance on 1.8V_STBY rail, make sure it's not pulled to GND. If you're getting on/off now - use Pico to diagnose, see this here:

    Xbox series x don´t power on

    you can use either MP2161A from MPS or RT5785C from Richtek

    Ps5 losing power in ps5 game

    This is going to be due to a failure of one of the CPU_Core or GFX_Core MOSFETs. Usually, UART will point you in the right direction, if it's CPU or GFX_Core MOSFET, if not - it's usually one of the 6 on the CPU_Core, because when GFX_Core ones fail, you'll get 2-sec BLOD (system won't even...

    Hardware Xbox One X - BGA piece NFD740, please help me to find it !

    yes, using HDMI2C4-5F2 chip. Funny enough, Microsoft went back to this chip for the digital revision of Xbox Series X console (White 1TB system)

    Hardware Xbox One X - BGA piece NFD740, please help me to find it !

    For those still looking for wiring solution for this issue, you can find the custom board i've designed for all models of Xbox it's used on (Xbox One X, Xbox Series S|X) on eBay: Xbox Series S|X Board to Replace U21/HDMIDP1-5F6 IC

    PS5 Slim beep no power no light (EDM-041)

    Reballing/reflowing the existing chip will not help, and if you're getting this error with UART - it doesn't necessarily mean that SSD Controller IC is at fault. If you can't test any further to prove that the chip is actually bad, then i guess your options are limited, so just order a new one...

    PS5 Slim beep no power no light (EDM-041)

    it's one of the APU power rails, 2 Ohms there is perfectly fine, and these secondary lines don't come into play until the system is up, so even if you had full short to GND there (or APU failure), the system would still power on for a couple of seconds and shut off. If you're only getting one...

    EDM 010 Component ID Help?

    you're measuring active 3.3V line from clock battery, what's why you're getting a "short" in there, remove the battery and measure again to confirm that there is nothing wrong on that rail

    Normal behaviour near F7002?

    yes, 200 Ohm is correct there on this revision of the board, and you should be getting 1.8V on the output (so 1.75V is fine if your meter is not very precise). The other power rail under the WiFi module (all other caps), you should be getting 3.3V on them, if you do - then everything is fine and...

    J20H104 instead of AW-XM501?

    because J20H100 version needs 2 power rails to the chip to operate (1.8V and 3.3V), just like XM501, but J20H104/XM546 versions only use one

    J20H104 instead of AW-XM501?

    worked for me, so you might have other issues on the board
