I have an older Samsung 3D TV. I purchased a Roku Streaming+ Stick. The HDMI port does not allow for the stick to fit behind the TV. I purchased a 180 degree HDMI adapter. The picture starts off fine. After a while of watching the screen randomly cuts out to black then returns. Eventually white snow type dots appear on the screen and popping noises start happening. I have to power off and on for it to go away, but it keeps coming back. Is the stick bad? Is it the adapter?
We recommend that you try plugging your device into another HDMI port on your TV. If that doesn't work, you can try seeing if there are other options in your TV settings for display type (such as 1080p) that you will no longer see the issue.
Please keep us posted once you have tried our HDMI extender and we will follow up on other ways to assist you.
Re: White Dots, popping noise, screen blanking out
The symptom you describe is usually a bad cable and, since you only have an adapter in place of a cable it is probably the adapter or the port on the TV. I believe that the extension cable mentioned by Danny has a good chance of fixing the problem. Of course any decent extension cable would also be an effective fix.
