My TCL 55P605 television is no longer outputting video. I have tried both external sources such as my Switch and PS4 as well as directly from the TV with Plex and Crunchyroll, and in all cases I get audio with no video.
Video was working fine yesterday, and I'm seeing that my TV updated last night. I'm now on software version 9.2.0 4501-30, and given the timing it seems like this could likely be the cause.
Is there something I can do to fix this on my end, or can you help me roll back the firmware? If the solution is indeed a firmware update, can I roll it back to the pre-November firmware? I've also had the issue I've seen others having where my HDR is extremely dark on PC mode.
Edit: To clarify, even though video from any internal or external source does not work, the screen itself is okay as the menu screens work perfectly fine.
