On July 18, my TCL Roku TV has developed an issue where anytime full-screen video is displayed, there are shaded horizontal bands on the picture. This only happens in a full screen, GUI pages like the Home screen, the video selection pages for Youtube, Roku Channel, Netflix, etc. are not affected, nor are the logo splash screens when loading a channel from the Home screen. Streaming channels as well as HDMI (Xbox One, Apple TV), USB (flash drive with videos) and coaxial input (over-the-air digital tv channels) are affected.
I have already contacted TCL, who suggested a power reset, then a factory reset. Neither of those options worked. The case has supposedly been forwarded to both Roku support and to TCL's engineers, but it's been nearly a month without a resolution.
Anyone else have this problem and, if so, has it been resolved for you? Screenshots below. Thanks in advance.
