The led light also dint light up. Already check the 0hms resistor 5V is entering. Any solution to find the fault. No Capacitor are not getting hot. Thank you in advance. |

Potato quality images aren't going to help. If 5v is going into the resistor is coming out ? Have you checked the power rails for shorts or for voltages, what is current drawn , what do you get from terminal, what tools do you have? Despite what youtube would have you believe, shorted caps on drives are the exception not the norm. |

It may be the potato images, but it looks disturbing, as if that NAND chip is crushed .. And is that inductor (? R47) missing a piece? |

Possibly damaged opening the casing, as long as it has continuity it should be ok though. The bottom nand ? - I thought that might be liquid or flux. |

It is not water damage, i use the alcohol. Wiat i will send the clear picture. The resistor 5V is entering and going out 5V. |

I think the inductor will be OK, despite the chipped ferrite. However, it does beg the question, how did it get that way? |

As @Lardman has already asked, what voltages do you measure at the inductors? They're those square thingies near the "GU2A" converters. Is that a crack in the corner of the leftmost NAND? |

Well, I think his tool just fly passed that zone creating a line ,The voltage regulator output according to datasheet is 1.8v ,This should be voltage for processor right |

I think these two SOT23-5 ICs are LDO regulators, but there are other possibilities with the same markings. FP6141-30S3G, Fitipower, 100mA, 3.0V, Ultra-Low Quiescent Current LDO Regulator, marking BE=, SOT23-5: https://pdffile.jiepei.com/pdf_file_D/20220411/pdf_pdf_jiepei/pdf8/FITIPOWER/FP6141-15S5G_datasheet_9084953/81764570/FP6141-15S5G_datasheet.pdf FP6141-18S3G, Fitipower, 100mA, 1.8V, Ultra-Low Quiescent Current LDO Regulator, marking BC=, SOT23-5: https://pdffile.jiepei.com/pdf_file_D/20220411/pdf_pdf_jiepei/pdf8/FITIPOWER/FP6141-15S5G_datasheet_9084953/81764570/FP6141-15S5G_datasheet.pdf The controller would require a Vcore supply of around 1V. I don't know what the NAND and I/O supplies should be, though. According to this PMIC ... https://www.qorvo.com/products/d/da006800 ... the SM2259 has the following voltage profile: Part number of PMIC -- ACT88325VA122-T Vin -- 5V Vbuck1 -- 3.3V Vbuck2 -- 1.1625V/0.95 Vbuck3 -- 1.8/1.2V Vldo1 -- 1.8V Vldo2 -- 3.3V This NAND decoder identifies the NAND supplies as "Vcc: 3.3V, VccQ: 1.8V/1.2V": https://nand.gq/#/decode?pn=29F64B2ALCTH1 |
