I have an issue with an Amazon Firestick 4K. I connected the stick to an HDMI port on my Onkyo HT-RC160 amplifier. From there the Onkyo is connected to a Vizio E55u-D2 television. This works great "most" of the time. The problem I am encountering is that after having the equipment turned off overnight or for multiple hours, I cannot seem to get the Firestick to "wake up". I press buttons on the remote and nothing happens. I let it sit for 10 minutes and still nothing. I can switch to another input source (DVD or UVERSE) and everything works for those sources wonderfully. If I switch back to the Firestick still nothing. After anywhere from 30 minutes to an hour, I can switch to the Firestick, hit the home button and everything works perfectly. I know my HDMI ports on the Onkyo are not 4K capable and have set the Firestick to only do 1080. I can't seem to figure out what it takes to wake this thing up. Any suggestions?
