DDJ-FLX 4 Usb Power Surge

Hello, 

I bought my DDJ-FLX4 from Argos in Sept 2023 but literally haven't used it until the last two months were I've used it on and off a few times, when I plugged it in yesterday on my Windows PC it came up with an error message of "USB Power Surge" and wouldn't power on, I've tried different cables and a different Mac laptop. 

When plugged into the power side the in and out buttons just flash on and off continuously. 

Does anyone know if there's a way to fix this or it broken? 

It's annoying as I've hardly used it and now I want to use it, it doesn't work. If I'd had used it from the start I would have known if it was broken. Pretty sure the warranty has just run out as well, rip.
