@allcoinminer, No haven't gone that far. While trying the different controller cables and power I did feel the heatsink and no matter what I tried the right hand blade did not get warm.
Right hand side with the ethernet port facing you.
ProblemTook delivery of 2 x S3 miners from batch 2. Out of the box one works fine the other only shows chain 1 as working.

Things I've tried- Tried 5 different CX750 power supplies
- Updated to latest firmware (Bitmain support said do this)
- Removed and refitted cables from controller to blades
- Swapped the 2 cables from controller to blades round
- Used combinations of all 4 6 pin power sockets, 2 front, 2 rear and other combinations
Nothing I have tried has worked. Bitmain suggested the firmware update and I've had no other replies from them
Not sure how removing the heatsinks and replacing the paste is going to help?
Any help appreciated
In your case reapplying thermal paste will not help.
It seems like your one of the blade is not even powered.
Have you checked for any pcb/pcb component missing/damages in that blade?
First do below steps:
Steps:
Disconnect the the faulty blade from the control board.
Unplug the cable which connects to the controller from working Blade. Unplug it from the controller side.
Connect it to the place where the faulty blades cable connected.
Now check whether the good blade still works.
If not working, your controller is damaged. Confirm it by swapping the controller from another working S3.
{
If not working, Try swapping the control cable and again not working, your did something wrong in this step or I have no cue. Contact bitmaintech.
If working, send you control board to RMA
}
If working, you now disconnect the cable from blade and connect to the faulty blade.
{
If working, Remove the control cable from the good blade side and connect the cable to the faulty blade.
{
If working, swap the control cable.
{
If working, your controller is damaged and send it for RMA.
If not working, current control cable is damaged.
}
If not working, Your current blade(faulty blade) is damaged and send it for RMA
}
If not working, swap control cable
{
If working, the earlier control cable is damaged. Confirm if by using a working cable from another S3.
{
If working on confirmation, Get a new control cable.
If not working, your blade and cable is damaged. RMA blade and Control cable
}
If not working, your faulty blade is damaged and RMA it. may confirm it by connecting good blade alone here.
}
}
*During all the above steps we are only connecting one blade, good or bad.
**Swap cable means, take out the connected control cable and leave it on your desk and connect with the other cable already on table.
OK, So I swapped the controller cables around.
Looking from the back of the S3 (where the ethernet port is).
1st try: Put left hand controller cable in right hand blade, other controller cable unplugged = bleeped and fans going full blast and wouldn't boot up
2nd try: Put right hand controller cable in left hand blade, other controller cable unplugged = fans going full blast and wouldn't boot up
3rd try: Put right hand controller cable in left hand blade, put left hand controller in right hand blade = booted up but showed only chain #1 @ 206-210GH/s
4th try: Left cables as the S3 was delivered = booted up but showed only chain #1 @ 206-210GH/s
I'm no expert but it seems that the controller might be faulty?
It seems the right hand controller on the board doesn't make the blade its connected to work.
I'm not happy taking the controller out of the other working S3 to test it, just in case I end up with 2 faulty S3 miners.
The mail/support options seem to have dissapeared from the Bitmain website login?
Should I just email them asking for a replacement controller?
