This comes down to either a: Faulty HDMI cable with a break in it. Damaged HDMI port with broken pins. 05-18-2021 04:59 PM TCL Roku TV stuck at red startup screen I have a TCL Roku TV (Model A105X). A couple nights ago, the TV just turned itself on and got stuck in the red startup screen. It sits there for a bunch of seconds then reboots only to end up in the same screen, and repeats forever. I have tried a bunch of things. Ive had this TCL roku tv (5 series S525) for a couple years now and have used it plenty but one day it turned it on and it has gotten stuck on the startup/boot screen. Ive done everything from unplugging it to holding the factory reset button but it doesnt do anything. If your TCL TV keeps going to the home screen, switching off the Wake on LAN and Wake on Wireless Networks settings is the first fix your should try. If the issue persists, ensure that the "Power on behavior" under the TV settings is set to "Last Input". The closest I can think of is that some of my stand alone Roku devices have remotes with two programable buttons. I have one button programmed for YTTV. The questions are whether such a remote is available for your Roku TV and whether pushing the button will turn on the TV as well as going to the programmed input. My tv gets past the TCL logo screen & stalls out on the 4 color rotating google TV boot screen for hours. Holding down the TVs power button puts me in android recovery mode where I can reset to factory defaults. Among other options. Resetting to factory defaults did not helps. E7ldD3P.
