Good day my friend,

I always have the same problem if my ASIC stops for some period of time due to lack of electricity.

Luckily I found solution for my S9 and T9 machines!!!

During start of ASIC you will need to blow with a heated fan(like your girlfrend uses for dry hair after shover) or industrial one.

You need to heat hasging boards while it starts and passes all tets. Normal working temperature of the boards is 40 degres Celcius  so they just don't receive enought temperature to check all chain.

I''m not a specialist and do not know why it works .

Good luck maybe it will help you too.

Most strange thing is that if you will disconnect power supply cables from the non-working board and keep data cable connected "Wrong chip index" error still trying to find working asic on that board and shows 0 asic. In the end just block miner hash possibility.

How it can be possible?
How controll board receive info from non powered board?
Or maybe Hash board was not power plugged at all after mulfunction?
