Rather than wait for Bitmain repair location to open post-covid to fix my DOA claim, I just sold my unit on eBay.
The S17+ 70 I got cost me less than $200 after applying Bitmain credit. It arrived with one dead board.
I got $650 for it on eBay.
And bought a S17+73 from a friend for $650.
All in all..... it was much better than dealing with Bitmain

Oh boy, a $50 coupon to make up for $3300 loss is nuts, i was not expecting them to send you a full refund, not even a half but most certainly not a $50 coupons.
It seems like they have gone broke or lost a ton of money during the past a few months, but you stay on it, stay persistent don't give up just yet.
Tell them you will go to court for this if they don't refund you some serious amount.

you must be persistent
be patient
be professional
be persuasive
be polite.
tell them that 50usd is far too small.
ask for 1000usd in btc to an address for a refund
you are in for 3300 and have two working boards.
you should get 2200 usd
but are willing to take 1000usd.
point to this thread. tell them they have given much larger amounts to other customers.

you will at least manage to get some refund in the end.
When you said some refund i wasn't thinking about value equal to 2 large pizza-s and a coca cola. And the value is in COUPON. Not only that they don't have anything for sale for months but also why would i even consider buying from them again.

Nope, not joking. That ^^ kind of stunts is why I stopped using BM gear years ago. Much prefer MicroBT (Whatsminers) and Canaan (Avalons). MicroBT are more efficient but the Avalons are better built.

Man i wish i could bring any good news but i submitted all documentation, was polite, sent tons of e-mails, told them that we had 3k+ usd in expenses due to fail equipment and 300+ USD in expenses due to DOA returned units.
And you know what their response was?
"we double checked with our leader we can apply for 23USD coupon for you " IS THIS A JOKE?
And then guess what, they doubled it:
"sorry what we can max compensate is 50 usd "
This has to be a joke? Jessica L. is bored and she-s joking with me.

Bitmain is sending me DOA units from repair all the time. And now one unit is 2nd DOA. Really not fair from their side, i am paying all shipping and everything so we can bounce back and forward scrap units. And their coupons mean nothing at this point as not only that they dont have anything else for sale but it is questionable that i will even consider ordering anything from them again.
It shouldn't be just "questionable" at this point, it should be "certain".
I have totally lost faith in Bitmain since last year, since the day they started using terrible thermal paste/solder and low-quality PSUs, I encountered a huge loss and 90% of the miners I bought from Bitmain except for S9/S9i/S9j have either lost a board or two, got a toasted PSU, arrived with fallen heatsinks, they are complete trash and everyone who doesn't plan on losing money on purpose should AVOID Bitmain for now and probably months/years to come.
Does anyone know any e-mail / website for local authorities in China who can assist in here? Cause if they can't fix it, i want a refund.
I wouldn't take this route, I suggest you stay consistent in your communications with them, send them as many Emails as needed, be patient and polite and request a FULL refund at first, and then slowly settle down for less, negotiating with Bitmain is like negotiating with a hawker, it's nothing like the other professional multi-billion enterprises, so you need to use a different way of communicating and if you are persistent and consistent you will at least manage to get some refund in the end.

Well nothing much really, but at this point i have nothing to lose. Returned them 2 units, 2 units came back. Both died within few hours. Again sent them 1 of them, i decided to keep one that works somehow with 2 boards, and the last one came in also malfunctioning ( works with 1 board ). I still can send it back for repair once again but whats the point? They will always send scrap back and that is obvious. I can also include some international authorities, i mean they can't just get away with this that easily by producing and selling scrap.
I just need some agencies, local or international. But the thing is i know that they can always say that they sent out a working replacement and that it died during transport and we can't do anything about it. If they wanted to find a solution they would, but they don't want. Its much cheaper for them to pretend that they are fixing units until the end of the warranty period.

What makes you think that there is a slight chance you can even be taken into consideration by chinese authorities? You are dealing with a comunist regime who participates in every aspect of local and national economy and business. The comunist party owns every company in China even bitmain which is highly profitable in every aspect of the chinese economy and energy industry. Not even in your wildest dreams any action against bitmain will go thru using the Chinese authorities. However, in the USA there is a legal figure called "Class Suit Action" and in this particular case it perfectly fits what it was created for.
All what is needed is several of us all together to file a legal suit against bitmain in the USA for wrongful and deceiving selling practices by selling and distributing defective merchandise and offering no warranty in the USA.
Bitmain is registered in the USA as a company so if there is a substantial number of people filling for a class suit action we may, at least, receive a full refund even if some time have passed.

First you have to install asic.to firmware (join Telegram group if you need help or read original thread - it has good tutorial): https://bitcointalksearch.org/topic/asicto-firmware-s17-95ths-t17-80ths-t17-40wt-s17t17-on-over-200k-asic-5208500.
Then you can choose one of presets (OC/DC) or you can manually type what frequency and voltage you want.
Keep in mind that this firmware is free but it has fee of 3% afaik.

Try using Asic.to firmware and undervolt or overvolt it a bit. That seemed to be a fix in most instances. Also, if that does not work, try lower frequency with higher voltage.
Dear favebook, please advise how try lower frequncey with higher voltage .. i have two t17+, it works with 3 chains without problem for only 3 days and after that one chip for each T17+ have 0 instead of 44. so with try lower frequency with higher voltage it have been solved ? how do this thing? please guide ....thanks.

This kit contains a few unneccessery stuff like Antistatic mat, gloves and even the DC power supply isn't needed here, he could use the miner's PSU, if he would open a repair shop he could probably invest in all those tools, but to simply fix your own miners and perhabs some of your friends', then my suggestion is to watch the repair videos and write down a list of the things they use.
Also if you are planning on buying the test fixture tool, I suggest you wait for a while, the latest one they have now is for the 17 series and S9/T9, and I am sure pretty soon they will make one for the 19 series, you might need that later on when you buy S19/S19pro/T19 gears, it would be cheaper to buy it once than having to buy it again when the time comes.
The tool to check chip problems is the same for s9/s17 and so on?
It doesn't need this course if he knows the basic things about Electronics and I think the other guide inside the course I think is how to flash the miner with SD card and how to upgrade the miner through web GUI.
He will need some repair kit for repairing like this image below.
For hardware related issues and SD card for software and fixture tool for diagnosing or finding the hashboard issue.

I can have all of this, i have a good environment and a separated clean space in my farm, its just to know where to start and what to buy and so on.
Obviosully I don't know what is inside the paid that course, my guess is that there is nothing worth buying in there, you can find free tutorials both videos and written format in https://www.zeusbtc.com/ the list of tools can be easily known by watching one of their videos fixing a miner, it's mainly
1- The fixture tool
2- A multimeter ( some specific models)
3- Heatgun
4- Solder paste
Those are off the top of my head, watch the videos and write down all the tools they use.

You need more than courses.
You will need tools 🧰.
You will need meters.
You will need a work station 🚉
In a clean room.
A lot of repair is desoldering of asics then soldering them back correctly.
Do you have good eyesight?
It helps to be able to do good close up work.
