Roku Model:4640X Black screen after reboot. Roku Ultra

Fri Jan 11, 2019 3:05 pm

Hi there, my little baby seem to have played in video setting and choose 4k resolution by error now my tv doesn’t detect the roku anymore.

Just after the roku logo booting the screen goes black.

After reading a few hours people seem to be using a remote sequence to reset the display setting; I tried all of them listed with no luck.

I don’t want to hard reset. Can anyone help me with the right remove sequence to reset the display setting.


Thanks a lot

The remote sequence may have changed in the new release. One thing you should be able to do is to move the 4640 to another TV When you do that it should read the capabilities of the new TV and if it doesn't support the mode you have forced, it should go back to Auto and pick a resolution your TV supports. Generally the Auto setting should work. Once you've verified the setting is Auto, you should be able to take it back to the original TV and it should pick a setting that TV can display.

You don't need a 4k TV (in fact, you probably don't want to hook it up to one). Dale is suggesting you connect it to any other TV and it should default to auto-detect and then you should be able to connect it back to the original TV.
