Topic: Antminer S9 dead hash board repair needed - page 4. (Read 5143 times)
Remember that the s9 board is a string design board. Any single failure point will cause it to stop working, most often this presents itself as a single bad chip. The problem with this is you cannot source brand new s9 chips to do the repairs properly.
If you go down this route please let me know if you're going to offer repair service to others, I've got a dead s9 hash board....
I'm in UK and have two dead boards in my Antminer S9, I'm thinking about buying a hot-air surface-mount rework station at about £1,000 just to change the easily obtainable power components in the hope that it's not the circuitry under the security glue that's faulty. If you have several more bad S9 boards and I can break a couple of them perfecting the fix process then PM me.
Not quite sure we're talking about the same kit though as you say 550 MHz and mine are about 4 THash per board.

Hi,
I have a dead s9 board too. Tried to contact bitmain warranty too (automated reply then nothing else).
I am in the EU too.
What I would like is to be able to send the board to someone to get it repaired then get it back. Bitmain China want the whole miner sending back! It's still functioning on 2 boards and doing 9Mh/S. Why send it back? It will cost a fortune and mean the miner will be off line for 2 months.
Anyhow, just sharing your pain.

Hi All,
I have plenty of dead S9 550 MHz hash boards and I'm looking to have them fixed.
I tried contacting bitmain warranty but they are not responding for last 15 days. The boards are located in EU.
Or maybe I can find some reliable tutorial how to diagnose and repair dead hash boards.
