Re: Flashing line at bottom of screen

I have the same issue. wired direct to multiple TV's, different hdmi cales, with and without amp it is definitely the unit. Seems to be more evident on google movies services and vudu when 4k is enabled. The green lines at the bottom of the screen seem to disappear when the 1080 p video is selected, so it seems this is only a 1080 p player and not a 4k player? also running buil 4111-17 version 7.5.0. A resolution to this common problem would be awesome.

I get a flashing green line (sometimes white) at the bottom of my TV screen whenever I am streaming from Amazon or Google Play Movies. Flashes about every 20 seconds or so and is quite annoying.

Roku 4 (can't get the firmware version at the moment)
Pioneer VSX-45 Av receiver
Vizio m55-c2

I managed to get a little video clip of it if I can upload that somewhere. Anyone know a solution?

You can upload to Dropbox or similar website (or even YouTube).  Just post or PM a link, and we'll take a look.

In addition to the above information requested, please also include any other peripheral devices that may be connected to your setup.

Re: Flashing line at bottom of screen

Just adding my voice to this, I have the Roku 4k, and have the same issue.  I thought it was the HDMI cable I was using, very glad that it is not since I just installed it in the walls, and have already drywalled over it!  I would hate to have to tear it out!

Re: Flashing line at bottom of screen

I have the same issue on my Roku 4
A green line at the bottom of the TV flashes somewhat often.

What's the deal?

Re: Flashing line at bottom of screen

I just got the tv about 1 week and a half ago and now there a green horizontal line going across the bottom of it. What can I do?
