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.
Model 4660RW
