Could we see the whole PCB? Sometimes it is easier to identify the IC when it is viewed in the context of its surroundings. |

I suspect that the part may be a load switch or a P-channel MOSFET, probably controlled from the DevSlp input. |

It's not the correct part, but it could be something like this: https://www.onsemi.com/pub/Collateral/FPF1039-D.pdf |

If this IC is the main load switch, then its On/Off pin should be controlled via DevSlp (pin #38). http://www.hddoracle.com/download/file.php?id=7418&mode=view The Vout pin should connect to the Vcc pins of the DC-DC converters. You photo is too poor, but I managed to find a clearer photo with Google. AFAICT, two of the regulators are marked with "AZ".

In this photo, the chip looks more like a fixed LDO regulator: https://cdn.mos.cms.futurecdn.net/LDpLp4YTVFL5bxYr577MeE-1182-80.png The small black square devices near the AZ parts appear to be load switches for standby mode. |

I think those 3 square ICs are probably something like these: https://www.onsemi.com/pub/Collateral/NCP435-D.PDF https://www.onsemi.com/pub/Collateral/NCP333-D.PDF http://www.ndone.cn/Uploads/image/file/20190801/20190801164219_79444.pdf https://www.infinite-electronic.sk/datasheet/3c-NCP433FCT2G.pdf |

BrandonMllr wrote: there was a similar problem, I still did not figure it out .. It's simple enough. If the IC is a load switch (which I now doubt), then run a wire link from Vin to Vout. DO NOT do this unless you are certain that this is indeed the function of the IC.. If the IC is an LDO regulator (which I now believe), then replace it with any suitable LDO with the correct Vout. For example, if Vout =1.8V, then you could substitute an LM1117-1.8. One thing that needs to be confirmed is whether there is a short between Vout and ground, in which case I would suspect a bad controller or bypass capacitor. |

Hello. I take advantage of the thread, because I have exactly the same unit. I attach detailed photos. Full Photo: https://i.ibb.co/XxV83PD/HFS256-G39-TND-N210-A-Full.jpg Detailed photo: https://i.ibb.co/80s1VPz/HFS256-G39-TND-N210-A-1-2.jpg https://i.ibb.co/mtJwhD2/HFS256-G39-TND-N210-A-2-2.jpg Sistomas: The unit when connected does not show any signs of life. The bios does not detect it and as is logical neither windows nor linux, it has been left connected for about half an hour and no chip heats up. I have looked at the voltage that it gives me in the same components that the creator of this thread puts and it gives me exactly the same as he did. I have checked the capacitors and the two input diodes and everything is correct. What else can I check? Does anyone know how to put this unit in safe mode? Greetings and thanks for the help. |

@DeVlL, what are the markings on the first IC at the bottom left ("CK PJ" in first photo)? What are the markings on IC1 - 5? I suspect that IC1 - 3 are load switches, but I'm not sure about IC4. Can you measure the voltages at Vin, Va, Vb, Vc, Va(sw), Vb(sw1), Vb(sw2)? What are the voltages at the Enable pins for each IC? Does the output of the first "CK PJ" IC connect to Vin? Does the 3.3V input of the first "CK PJ" IC connect to Vin?

Here are your answers to your questions. what are the markings on the first IC at the bottom left ("CK PJ" in first photo)? It's a CK QP Can you measure the voltages at Vin, Va, Vb, Vc, Va(sw), Vb(sw1), Vb(sw2)? They all give me 0 voltage What are the voltages at the Enable pins for each IC? They also give me 0v voltage Does the output of the first "CK PJ" IC connect to Vin? The CK QP is connected to VIN Does the 3.3V input of the first "CK PJ" IC connect to Vin?[/quote] THE CK QP gives me 0v I think the solution is in the input. Here I show you the measurements at the entrance. My question is. Could it be that the Rom bios is corrupt and there is no voltage for it to start? And from there my previous question. Does anyone know how to put this unit in safe mode? Thanks

Here I show you the measurements at the entrance. It does appear that "CK" is the main switch. My question is, is this switch being switched on? There should be a DevSlp pin on the m.2 interface (pin #38). Does it connect to the diode in the middle of the PCB, or does it connect to the "CK" chip? http://www.hddoracle.com/download/file.php?id=7418&mode=view http://www.hddoracle.com/viewtopic.php?f=106&t=2506 DeVlL wrote: Could it be that the Rom bios is corrupt and there is no voltage for it to start? That doesn't make sense. The two MP2162 ICs produce the Vcore and Vio supplies for the flash controller. If there is no voltage, then what does it matter if anything is corrupt? DeVlL wrote: Does anyone know how to put this unit in safe mode? Why? My approach would be to determine the pinout of "CK". If the output of this chip is not shorted to ground, and if it is indeed a switch or e-fuse, then it should be OK to jumper its input and output. If you can tell us the markings on ICs 1 - 5, then we may be able to identify them and their manufacturer. This might make it easier to identify "CK". |

Can you confirm if this is the pinout of "CK"? Code: +3.3V in O O output +3.3V in O O output +3.3V in O O ground Can you measure the resistance between the outputs and ground? Can you confirm the connectivity of the m.2 DevSleep pin? Attachment: DevSlp.jpg [ 187.4 KiB | Viewed 19175 times ] |

Can you confirm the connectivity of the m.2 DevSleep pin? Attachment: The attachment DevSlp.jpg is no longer available I think the culprit is definitely CK QP. Here I detail what you ask for and the conclusions that I believe the fault is in the CK QP: Can you measure the resistance between the outputs and ground? The measurements give completely crazy values, they go up and down. It is not a fixed value. Can you confirm the connectivity of the m.2 DevSleep pin? If there is connectivity to pin 38 DevSleep. Now I attach an image of the CK QP. As you can see in the image the CK QP has a broken corner (I hadn't seen it because I don't have a microscope) I remembered that I had saved a USB microscope here and that is the image you see now. In the second image with the measurements, it confirms that the possible failure is the CK QP. What do you think? In a while I'll edit the message and tell you exactly the ICs from 1 to 5

Your measurements would suggest that there is no short between 3.3Vout and Ground. Your measurements would also suggest that 3.3Vout in connected to Vin(3.3V). If this is correct, then it should be safe to connect a jumper wire between 3.3Vout and 3.3Vin.

If this is correct, then it should be safe to connect a jumper wire between 3.3Vout and 3.3Vin. So if I put a cable between those two points, in theory the bios/windows should detect it. So is it a fuse? |
