I have a Roku Express connected to a Sharp 40FG3141K by HDMI cable. The Roku got the latest software version on Friday 25th May. Since the software update I having an intermittent problem. If the TV is on standby and woken by pressing the Home button on the Roku remote the TV starts fine but there is snow on the Roku home screen and the snow remains if I go into any of the apps. If I go into the system menu and restart the Roku then the screen is fine when it reboots. This seems to happen roughly every other time the TV comes off standby.
Model: 3900EU - Roku Express Serial No: YG009M707872 Software version: 8.1.0 . build 4113-51
