If the new power cord does not fix this then you need a new Softbox. If it’s within the a year of your purchase you can get a new Softbox for a small restocking fee of $40 for the 4k Pro, and $60 for the X.
If it’s been more than a year, you can still get a new box at a special discount using the coupon code: SPECIAL17 Buy one NOW
