Hi everyone! Can someone help me find power schematics of this SSD TeamGroup CX2 SM2259XT2G The SSD powering with PC3000 Shows 0A on 5V Shorting pins Controller cannot go to ROM mode Many thanks!

Absolutely flat lined at 0 from power on? break it down from the sata power in, if youre getting nothing something very easy is blown open.

I did measured the resistors around in resistance mode. None of them are broken. The only thing that gets slightly hot. Like 30 degrees C is the controller Yes.

What is the voltage across each of the coils? If the controller heats up, then the 5V input fuse is fine. Some voltage is missing.

Doesnt exactly fit with a 0 flat line but check the cap near pin 1. Im sure Erkin just posted a video of a swap on one of these with a dead controller, Its not the first play Id jump on and I think his was an obvious short.

Check the crystal. Measure the voltages at pins 1 and 5 of the SOT23-5 IC (618 + 00022). I think that may be an LDO regulator.

10 boards for US$100, or 1 for US$26. Just add NAND. https://www.aliexpress.com/item/1005012246729144.html https://ae-pic-a1.aliexpress-media.com/kf/Sacfdec960a44442bbb3f11cff1011891o.jpg https://ae-pic-a1.aliexpress-media.com/kf/Sb44d505c366648d482f5ba94f67ca51dt.jpg https://ae-pic-a1.aliexpress-media.com/kf/S433427b9c6a34f929a64043f9f77f372n.jpg https://ae-pic-a1.aliexpress-media.com/kf/S5e22d1c927f143b99d1eba07762313b3C.jpg

Sorry, my question was unclear. I only needed the 5.1V/3.3V readings. That IC is a 3.3V LDO regulator and is OK. It's a long shot, but if you shake the PCB against your ear, can you hear any rattling? If so, then that could be a shattered crystal.

You most likely have a damaged controller.

Nothing is rattling If you don't have an oscilloscope, you could try replacing the crystal, but a controller failure seems more likely. One other possibility is a shorted capacitor on the reset pin, but that's unlikely.
