My Roku Premiere+ has been working fine for over 2 years with the same TV system. There are no other TVs or Rokus. It worked fine on the evening of 09/02/2019. On the evening of 09/03/2019 there was nothing but a black TV screen showing "HDMI 1, Cable Box". No Screensaver, no Home screen. Here's what additional info I can provide:
1. TV - Sony Bravia KDL-52W3000, Sound bar - Sony SS-MCT100 2. Roku box - #7AK681577608 model 4630X, Remote model RC-GR3 3. New remote batteries 4. Unplugged/re-connected box power/HDMI/ethernet cables 5. Re-paired remote to box 6. Pressing Home button turns on white LED on box 7. Pressing any other remote button causes white LED to dim and flash rapidly 8. Ethernet connection, not wireless 9. Computer internet works fine 10. Unplugged/reset all routers 11. TV works fine receiving programs over-the-air via outdoor antenna
Could the Roku box have just "died" and I need to buy a new one? Any suggestions? Thank you.
When you first power up the Roku, do you get the dancing letters on the screen with the boot sound? If not, then it does sound like it's toast. If you do see the boot screen, then I'd next try it on a different TV, perhaps with a different HDMI cable. If it's non-functional on a 2nd TV, that pretty much eliminates anything other than the Roku itself.

I think I figured it out. My system uses a 1 to 2 HDMI splitter. It's making a steady buzzing noise - used to be quiet. I connected the Roku directly to a different, stand alone TV. It works fine. A new splitter is on the way and should solve the problem. Thanks.
