First, pardon me for bad English.

My A8 is restarting when it is preheating, so in order to test I disconnected the cable from the bed and put in the options the temper at 30 ° (if I try otherwise it will restart). It seems that there is no power passing (I tested directly on the board) that is a defect in the board?

I’ve been with her for 4 days and I’ve only been able to use it 4pa times until this problem happens.
