I have a Samsung 840EVO 500GB SSD. I need to read inside it. It presents a broken part, with a bubble on it. Something was wrong with electricity, this is a simple part that I could try to replace with a little soldier. But I need a replacement part. Please help.

That chip is fried. I have no clue where you could order a part like that unfortunately.

Many thanks, Could you suggest me what to do? I noticed, in a similar schema, that this drive has a version without this part. I could detach and try to start it.

buy the same drive and take what you can from the first drive and put it on the second. If it doesnt work put it back.

That chip is a Samsung-specific DC-DC converter. You'll have a very difficult time finding a replacement, if that's possible at all.

You need a doner drive.
Look on ebay for a used a 840.

Going from these pictures, you can probably use a 120GB to save you money.


Then you need to desolder that chip and resolder it onto the broken drive.

However that might not fix the problem. It could of burn out in other places and you be risking bricking the 120gb.
Luckily its only a 25 dollars.
Depending on how good your solder skills are its quite a tricky solder job honestly with all those resistors.
I don't know if i personally would be comfortable attempting it.

You may want to call around repair shops and see if they will attempt a solder repair if your not the best with a solder.

feel like OP will never return. But hey i didnt even look at the 120gb version good point if it has the same parts even less risk.
