If you want to sell any of your dead gear instead of watching it do nothing, shoot me a PM. Shipping might be too expensive to make it worth it, but maybe not.
Shipping from where I live to the U.S will sure cost a ton of money, the same thing to China, it's why I throw away most of the gears that die on me, but depending on your offer we might work it out especially if you only need the hash boards and not whole miners.
I'll confirm what do I have left untouched and send you a PM accordingly, I know I have hash boards of these models (S17 pro, S17, T17, T17e, S17+) I just need to confirm the numbers.
Thanks, let me know what you find. I have a bunch of APW9s, so one option is to just remove the PSU which is ~40% of the weight.
So if your boards are failing you can always try different angles to get them back to life. Worth a try, hopefully it will work with your gear as well.
I've seen a lot of excess solder that dripped down from heatsinks on hashboards I've repaired. The solder forms small solder balls that can sit right between the exposed pads for the chip connections and the bottom of the heatsink. It can sometimes be very close to shorting out signals, and just a bit of pressure on the heatsink can cause it to touch the signals and short them out. I'm sure the opposite is true as well, so a bit of pressure in the right spot could pull the solder away enough to open a short.
Every day I spend up to 10 hours on the same hash board and new problems are constantly born, problem Chain 36 after a while an error appears chine 21 then chine 6 then Asic 0 and so constantly, a lot of trouble for a beginner, and those from Zeusbtc will not really cooperate,
I find that very frequently heating and removing a heatsink will melt excess solder on nearby chips causing other issues. Also just handling and flexing the board can expose other issues. Especially when starting out, it is a good idea to test in stages as you put chips and heatsinks back on. I set the test fixture to only do the asic count test (this can be set in the config.ini file on the sd card, Only_find_ASIC=1), and will test the board before applying either heatsink, then after applying the back heatsink, and again after applying the top heatsink. Many times the board will find all chips fine, but after applying the back heatsink for the chip I'm working on I get 0 asics.
