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?
So Roku been aware of the problem and you keep telling customers it’s their power unit which cannot be the case in every case because even after we follow your specific instructions the device still shuts down which means it’s the device itself and if that’s the case I would like a refund on all 3 devices I have purchased within a month time and now all of a sudden it’s just keeps shutting off or freezing even after it’s reset
