I purchased my Roku on Saturday and installed with no issues. I went to use it yesterday and it did not work. Via a chat session with tech support I was able to re-pair the remote and get it working. However this morning it stopped working again. Serial number is SOBY41DS623W. I just ordered a HDMI extender cable, will this fix the problem?
I need to mention that the I can turn Roku on and off with the remote but there is a blank screen.
@Neilgiac, Rokus don't turn off. That power button on the remote is solely for the TV. Some Roku devices will go into a "power saving" mode after 20 minutes of non-use. Pressing Home (or any of the non-TV remote control buttons) will wake it from power saving. You can disable power saving under Settings->System->Power if your device has it.
