Memory Batch Requirements for HIKVISION DS-7216HGHI-SH/A, DS-80195 REV1.2 Motherboard, 25Q128 SPI

Question

Hello. Required memory batch for HIKVISION DS-7216HGHI-SH/A motherboard DS-80195 REV1.2 SPI 25Q128 memory. Inverters started, but no reaction. Regards

Hello Did you manage to launch? I have the same model with damaged capacitors, I have already replaced it, but the recorder still does not start.

Hello, I did not download this upload from this Russian site. I'm waiting for some twin DVR to arrive for repair. Regards

I have 2 pieces and both are the same, capacitors and power supply. Could it be that the flash spilled from the power supply?

gradek83 · Answer

What does it look like from the inside? Is the power supply inside the case? Input from the link above. Before uploading, make a copy of the original batch.

pszyc · Answer

The capacitors in the power supply dried up (the output was 5v), the external power supply and it's already fixed. All the capacitors on the board are dry. After replacement, the recorder lights up the LED indicator and turns on the fan. After connecting to rs232 in the board, there is no communication with the computer. The bootloader is not visible. The voltages on the board as in the picture. I haven't taken out the flash yet. I'm wondering about this 1V, 1.2V and 1.4V.
I have two pieces and both cases are the same. They were mounted in different places so I rule out overvoltages.

And from the bottom, what does the board look like, is this SPI 25Q128 memory there? Does it get 2.7V to 3.6V?

Sometimes you don't know what system this board is on, but I'm betting on HISILICON ... somehow I didn't find any information in the specification.

pszyc · Answer

25q128fvfg 16 pin. Pin 2 is 3.3v. Tomorrow I will have a programmer so I'll see what's in there.

gradek83 · Answer

From the front you only have RS-485 you mean UART on the motherboard? If I'm not mistaken JP2 connector (socket). In general, when the power comes to the SPI memory, if I'm not mistaken, the bootloader should speak anyway.

pszyc · Answer

Yes uart on the motherboard next to the processor (total silence). As the flash spilled out, the bootloader will not work.

zembe · Answer

My disc has the same voltages as my friend's. In my case, the fan does not turn on, only the "power" LED is lit. I can read from memory, but I can't clear or reset it for anything.
Correction, the fan would spin too if it wasn't seized.

Are you reading from the unsoldered system? What exactly is the designation of this SPI. Did a colleague compare his batch with what I attached in the attachment?

zembe · Answer

Yes, it reads from the desoldered chip in the programmer. Exactly 25Q128FVFG Winbond. They are identical in size but different in content. I'm posting the one I managed to download.

pszyc · Answer

I read the contents of the bone and it turned out to be completely clean, I programmed the images shared here and the recorder still does not start. The system is cleaned and programmed without any problems. Anyone else got any ideas?

gradek83 · Answer

So I understand that after desoldering the bones and ripping, there was nothing, and when you uploaded the batch, one of those available here and after verification and soldering, there is still no response even in the Terminal via UART.
Post a picture from below if you can.
And label these systems.

pszyc · Answer

Silence for sure. I uploaded and verified the batches, even after removing and re-reading the system, the batch was correct.
layout description
1. AHRF039
2. MPFF8636
3.RS3080
4. RTL8211E
5.TPF143
Maybe someone has a schematic for this crap.

gradek83 · Answer

Send a close-up photo 1 and 2 I didn't find anything after the markings.

After replacing the capacitors, you checked with a multimeter on the diode test whether the capacitors are charging and whether there is a short circuit to ground.

Anyway, it would be worth finding out what is under the heatsink of the main processor. They are usually glued on thermally conductive silicone. You can heat the radiator with a dryer and try to gently wrap it around it, or cut off the radiator with a thin wire, fishing line or even dental floss so as not to damage the system. Either way, it's going to be hard to come up with a diagram. It's a pity because I see that the equipment is not that bad.

pszyc · Answer

The processor is on bga, so I will not approach the meter. There are no short circuits on the risers. The voltages are even and stable. This must be a common glitch since it's the same in all cases. I read the flash from the second recorder, it was also empty.

gradek83 · Answer

It turns out that this 1V is the correct system No. 2 is MPQ8636GL-10-P

pszyc · Answer

No. 1 is also ok. There is 5V. What else would you attach to? Maybe someone else has another batch. Whipped up?

gradek83 · Answer

It's possible, but we don't even know what kind of process there is, the manufacturer doesn't boast either. You won't know until the radiator sits on it.
Or the quartz fell, I just rather doubt it. You can check the voltages on the quartz, usually one side has a little more voltage than the other. Either way, it probably won't work without a frequency meter.

zembe · Answer

The recorder went to scrap.
