What is the problem with your old board? This is not just a pcb swap on this one there is adaptive data that needs to be transfered to the new board to make it work for you. There is a lot of posts here on this one if you are interested in reading some of them to find out.

She fell completely electronics - a circuit for connecting voltage is overheating. I have this drive over 100GB of photos and videos of my son and I would not want to lose.
Sorry for my English.

Changing out the board alone is not going to solve this problem. There is adaptive information on the board that needs to be moved. Either by removing which is unsolider chip and move to new one or by special tools. That is to say if this is acutally your problem on this drive. If you have a DR company in your area take it in for a free estimate and see what they tell you. Do not just go about changing parts and in the end you have lost or the repair is much more expensive to you. You can buy parts here on the forum but after you get them and do not understand what to do with them. What will you do then. Buy more parts?

I understand what you mean. A little after I asked and learned that the exchange of electronic boards resolve the matter positively. Although the data from the disk are very important to me but I do not want to overpay for recovering data to a company because it's the cheap should not be. That is why I want to try to repair itself.

hi,
i have this PCB in stock. and you need soldering original ROM chip from old PCB to good PCB. please feel free to contact me if you need this board. thanks.

I want to try to repair itself.

Can you describe the failure symptom a little better?

If you upload a detailed photo, one of us may be able to help you repair your board. Many times the problem is only a shorted diode, in which case it can simply be removed.

Good luck.

On the back of PCB noticed a damaged item. Photo below:


When voltage plate heats up more or less in this area. But I'm not sure. The following picture across the PCB:



What do you think about this vulnerability? Replacing the entire PCB?

[fzabkar]

The damaged part (D6) is the 12V TVS diode. You can simply remove it with flush cutters. If there are no other problems, the drive will work without it, but it will no longer have any overvoltage protection on the 12V supply. Just be absolutely sure your power supply is OK. You should also confirm the resistance of the zero ohm resistor, R82, to the right of the diode. It's probably OK since the diode is heating up.

If you intend to replace the entire PCB, then be prepared to transplant the serial EEPROM chip at U12 (between SMOOTH chip and Marvell "big M" MCU) from patient to donor. This chip contains unique calibration data.

You may want to first test the PCB while it is disconnected from the drive.
