Antminer L3 all Hasboards on X

[Schindla1102]

Hello Guys,

my Antminer L3+ stopped working yesterday at 5AM.
He was running for more than 2 month without any issue.

The thing is that he starts up, everything fine with no X an any hasboard but he has 0 Hashrate. After ~15 to 20 mins all Hasboard turn to X.
I changed the pools, restarted, resetted and flashed the firmware again, nothing helps....

He is located on the attic with a current temperature of -7°C, can this be the problem?

Can you put it in a warmer environment and let it warm up for an hour or two before turning it on?
Might be a bit too cold. From the bitmain website:

Operating Temperature: 0C to 40C.

Power supplies also don't like it that cold.
Also, at that temperature condensation can be an issue.
