New bug in V14.0.4 release: pressing the power button on the remote, the TV powers on then immediately powers off. This is a NEW PROBLEM. It is very easy to reproduce.
TV is a G140X from TCL. See issue ID OU-424-510 from 10-21-2024.
The remote is wireless. (something I was involved in developing a decade ago)
Possible reason for the problem: the remote sends a WIFI WOWL packet to wake the TV, but it also sends an IR power-on event which must be ignored in the firmware. Please pass that idea along.
