Did you buy this unit directly from Bitmain?

It seems few of your hashboard have EEPROM issues that causes "ERROR_SOC_INIT"
If you bought this unit 2nd those 2 hashboard are replacements and they only flash it with modified firmware to bypass that issue. Usually, you need a code editor to be able to fix this issue.

However, since detected chips on two of your hashboard are abnormal you must hire a technician that could repair ASIC machines. Bitmain repair center is nice but I suggest you check this https://www.zeusbtc.com/ASIC-Miner-Repair/

Look for a repair center near your area because sending it back to Bitmain will cost you more than hiring ASIC tech near your location.

thank you for your reply again, much appreciate your expert opinion. Yes i bought them from second hand...
I have reviewed the repair centers from Zeusbtc in Europe (as I am ehre) and repair cost range from 200-500EUR per one, so I decided I would like to repair them on my own. can you let me know what tools i would need? to repair 5 hashbaord it will cost 1000-1500Eur so i can do it(I repaired my S9 in the past with PICkit and some heatsink replacement, no chip replacement yet, but like to learn) on my own, save, learn something and have tools/knowledge for next repair.
