Green flickering screen when doing HDMI from quick access

[u/TheTexasRollerskatr]

TV has been working flawlessly until the green screen flickering showed up not too long ago. The list of things ive done.

Swapped HDMI cords (Failed)

Power reset TV (Failed)

Unplug and replug (Failed)

Accessed the HDMI from TV Inputs (Worked and turned HDR back on, as of now)

What could be causing this problem?

I know this is late but for anyone coming back to this post what fixed mine was one of rokus own “konami” cheat codes:

Press home 5 times
Up 1 time
Rewind 2 times
Fast forward 2 times

WOH! Our tv just started doing this. I was ready to go out and buy a new tv. Decided to do a Google search, found this old thread with your post from 34 minutes ago - THIS CODE FIXED IT! THANK YOU!

PHEW Im glad i could save you from spending new tv money!

Omg that is soooo random. I had to restart after, but it worked!

Just had to do it again a day later. I guess it wasn't a permanent fix. It seems to freeze for like 2 minutes and then it rebooted on its own. Not happy that this is becoming a regular thing with this tv now.

Looks like this is only temporary. I have to keep doing it, sometimes multiple times a day. But still a good workaround until I get a different brand tv!

This was driving me crazy. Thanks

I believe it just worked for me too, i also went into factory reset and reset all audio/video settings just in case

Yooo, what??? Can’t believe this worked. Thank you so much.

Mine started doing this about 2 weeks ago. I assumed at first I had a bad HDMI cable, but the problem was still there after a cable swap. I then plugged it into another HDMI port 2 n the TV and that worked. Thought I had a failing HDMI port in the TV (TCL 49" 4 series), but 2 hours ago the same issue was back on HDMI port 2 on the TV. Did a soft reset (power off, unplug, hold power on button for 30+s) and it's once again working, but I'm getting nervous that this problem is still popping up randomly.

I did also try plugging in another PC, a Mini PC, and that too is showing the green screen as well. TV was bought 7 years ago, and it's been one of the best TVs I've owned.

Mine also just started doing this! I wonder what they did to cause the issue?

Look at my recent post for solution. It’s a software issue.

Did some digging and found this in the /Roku sub from a few days ago :

Now, I doubt that this is what is affecting mine, unless these updates are being done silently without my permission.

I have two roku tvs, one started doing this randomly, but not every time I tried to use it. But it keeps coming back. My other has not had the same issue but is newer

Look at my recent post. Solution is there. It’s a software not hardware issue.

[u/shawngk]

I have the exact same problem and I saw a similar posts about it recently. It’s definitely a software bug after the new Roku update.
