ML5 does not power up

Hi everyone, I am using the ML5 since quite a while now and have never had an issue with it until now. Since two weeks, it won’t power up, when I connect it to my power supply but, and here’s where it gets interesting, when the device is cold, there are no issues. I have tested it by putting it in my fridge for 1-2 hours and it worked fine after that. Has anyone ever heard of this behaviour?
Thanks for helping!

That’s really odd. When the device reverts to room temperature it stops working again?

Yes, it powers up once, but when I pull the plug and want to play it again, it does not start.

Can you get in contact with us via email with your order number and ML5 serial number? thanks!
