I bought an intelligent harmony machine.

It doesn’t power on when it is chilled.

The specification of it says it can work in temperature between 5 to 35 ℃.

But it doesn’t work under around 15 ℃.

I made it chill to 8 ℃ in a refrigerator, it didn’t completely power on.

And I made it warm with a hairdryer, it turned on.

I reported this problem to music instruments store, and the store made the distributor in Japan to send me another new one.

They said the new one was changed some parts and the problem was solved.

But the new one doesn’t power on when it is chill again. The problem is same as before one.

Does someone know how to solve this problem?

Music instruments store and the distributor in Japan don’t know how to do.
