Light on the Power Indicator Dies out

Hi!
I use a uArm swift pro. There is no light on the power indicator when plugging in the power. There is light sometimes but gradually dies out.
When connected to PC, uArm Studio can detect the arm, the arm has the beep sound and has weak light on the power indicator.

Is it a hardware issue of the power cord?

Thank you!

Hi friend,

Please try the 12V power supply.
Is it happen when you receive the uArm? Please provide the SN.
