Hello guys!
Could you help or advise me something to figure out what's wrong with this motherboard?
There is a shortcut somewhere. On the first picture the, I marked a resistor, a few condensators all over these and all next to of the NANDs are shorted and shows ~ 4-5 Ohms of resistance. The second picture shows exact voltages from a good ssd. (measured with a Chinese multimeter
)The voltage regulator is a http://www.ti.com/lit/ds/symlink/tps652510.pdf.
The 1,0x Volts are needed for the contoller and the 3,0x for the NANDs.
In the defective SSD these values about 0,3 and 0,5 Volts, the device itself consumes about 3 Watts and the contoller becames really hot within a few seconds.
Thanks in advance
