Thank you for your advice.
As you mentioned the manual procedure link, tried to meet the procedure correctly.
but when I connect it with USB, the display and others working well.
But when I tried to connect AC adapter, the plus occurred spark and the main circuit breaker became 'off'
So cannot use the product now.
Please confirm this AC adapter is failed item or not. After your confirmation, I will request replacement to Mouser which I bought from.
Thank you
