Roku Express 3900x keeps shutting off

I bought a Roku Express 3900x for the kids for Christmas. It had been working without problems for the first couple of days. But since yesterday it only comes on for a short time (like 30 seconds) and then it shuts off and the white light on the device flashes twice, then stops, then flashes twice again and so on. The TV screen goes blank saying "no signal".
Has anyone experienced a similar problem or does anyone have any suggestions about what could be the problem?

Are you using an official Roku power cube for it? That sounds like a power issue. Just a guess...

Yes, it's the original Roku cable and plug that came with it.

I just tried it with another cable (a phone charger) and there a red light came on and it didn't work at all. So, it seems to be a different issue.

It definitely sounds like the power supply, but since the whole thing is new, I'd suggest returning it for exchange. This isn't normal.
