Do you have a less primitive mean to try to repair it than an oven? It was the only suggestion made to revive a board that i have no real use of unless it can work. If i can't revive i'll probably ship it to sidehack and thats that.
Doing this does not seem like it could damage the chips, so anything goes.
I'm very interested in any other suggestion pertaining to this.
All the other options require expensive equipment and a lot of time. My friend has equipment for repairing,
but he does not have time for this.
The question is why the previous owner took it off for the first time?
Why does he use the wrong screws without springs ? With the greater pressure on the blade and ships with wrong screws, he got it to work or not? Did he get the blade to work 100% ?
It was not working, was sent to Bitmain and was returned with parts missing and the blade still not working. He messed around with it after that and did not manage to make it work. It is possible that it was a simple issue and was made worse.
Regardless i do not have many options to try to make it work and as i have pretty much paid nothing for it, i can only improve the situation by messing with it further. As long as i do not break the chips that could be salvaged, i don't see any issue whatsoever.
Edit i would like to add for clarity, this is what happen when i run it alone on a controller;

question does the lite on the board lite at all , it going to keep showing all zero with one controller it still sees it but for some reason a power or some thing like it on the board won't work or let it connect which can be a bad solider or it needs to be remelted etc which is why reflowing might work or it can just be gone,the chips may be ok just the power line part is bad, i don't even know how to fix that unless you know some one like he said with the right gear and time . reflowing is all ways a last resort and cost nothing and might even work . I sent two S5 boards to some one after I reflowed them he told he got one working so far , so reflowing it won't shouldn't hurt the chips unless you leave it in there to long and i did it as a last resort.
No light, no voltage. Dead. The reflow did not work. I tried 180c 6 minutes then 190c 10 minutes but my oven must of went a bit higher since my laser thermometer went to 205c.
Still no difference. Its like its properly connected, but is not powered. Pretty sure thats what it shows when you have a board plugged thats not powered from memory but can't go test it.
Did you get that miner used ? Too many screws . Wrong black screws and self-drilled holes in blade.
You have been scammed by seller this miner. Yea he right they should all be sliver with springs on all of them. The screw hole look ok . just some screws don't .just looked at my S5 that came direct from bitmain it has the same holes with all silver screws with springs on every screw.
You have one unique board. I have never seen the double screw in previous post. It is interesting though. Was a blade sent into bitmain and that blade sent back? Just curious if bitmain employee did it or odd batch.
But the paste looks pretty bad. I would get some cleaner/purifier if you want to do it right. And clean all the chips get the old stuff off. Then put on a light covering on entire chip should see paste on all of chip.
The nice thing with some of the pastes above is you would get multiple trys with the tubs vs the higher priced stuff. So for troubleshooting on thermal paste I would go for the tub with quite a bit of quantity of it.
I think i'm the 3rd owner. Or either way i'm missing a good portion of the story. I just know it was long and annoying and in vain.
The working board has double hole as well, with the default screws+string however. The miner was sent to Bitmain from the last owner, which received the unit back with the defective blade still, and missing the metal bracket that hold the controller in place.
I think he mentioned it working at first for a bit but then dropping after some amount of minutes. He might of tried to fix it and eventually it just died for whatever reason.
It still doesn't work so no point in repasting it. If i can't fix it, it will probably be used as some sort of payment/support to Sidehack.

) and give us a good shot of the whole board. Maybe we can see the problem.
