Hi! I have a TCL Roku Smart TV model: 50S423 that's 4 years old. I was watching it today, and then I paused it during a show and I couldn't un-pause it with the remote (the screen was stuck on the floating screen saver). I couldn't turn the TV off with the remote, so I unplugged it, waited a half hour and re-plugged it into the wall outlet. The light blue light at the bottom of the TV on, so it seems like there is power, but there is not visual or audio.
Things I have tried so far:
*changing batteries for the remote control
*unplugging and re-plugging power supply, as well as HDMI, ethernet and power cable.
* trying to login via app on phone to use it as a remote -> the app isn't picking up the device at all.
Any advice much appreciated.
Thanks
