Problem: Roku is slow to wake when the screensaver is on. When the TV is off and I turn on the power, the screensaver is displayed for 5-10 seconds after the TV comes on and the Roku will not accept any inputs. This started 1-3 months ago. Sometimes there is a black flash on the screen a few seconds after the Roku displays the main menu. Previously the Roku would exit the screensaver within 1 second.
I have tried:
Restarting the Roku
Changing screen savers (tried Nautical and aquarium)
Changing display resolution from AUTODETECT to 1080P
Roku Mode: 4670X
Software: 9.3.0 build 4170-46
Roku Uptime: ~1 day
TV: 2011 Samsung PN51D6500 which has a max resolution of 1080p
While I do have a AV receiver, the Roku is plugged directly into the HDMI port of the TV.
