Playback Issues - Audio/Video & Power

[Morales07302]

My Ruku Ultra video and audio are randomly blinking off for about 1 to 2 seconds at a time.  Sometimes is video, sometimes it's just audio and sometimes it's both.  This will happen every day.  This started about two weeks ago. The only way to fix it temporarily is to restart the device.  Is the device failing?  Is the firmware version no good?  Please help.

How are you powering your Roku -- plugged into your house current or into a USB port on the tv. Most tv USB ports don't provide adequate power to run a Roku reliably. You may be able to run at the ragged edge but minor variations of the power output of the USB port can lead to the symptoms you describe.

Well, we can scratch that one off the list. some things to check/try:

Make sure both ends of the HDMI cable are firmly inserted.

Try a different HDMI port on the tv if it has more than one.

If you have another USB power adaptor handy that is rated at least 1 amp try that instead of the one that came with the Roku.
