Case of Power Supply

Today, a client told me that his Hitachi Doctor can’t work normally. The console will beep twice at power on and it automatically switch power off then. According to my experience, I know it is problem of cables or power supply.

First, I asked client to enter menu of Power Monitor and found Power Status is “Reverse Voltage”. It’s generally caused by wrong connection of power supply or bad power supply.

I asked client to replace power supply and after that the console works completely well.
