Why is my TV no longer responding to remote?
I have a Vizio E3D470VX smart tv which stopped responding to remote commands. I have tried all suggestions on YouTube regarding Vizio with no results. Quick story—tv powers up and responds to remote commands but after several minutes it no longer responds. If I push the power button to shut down, the screen goes black after a few seconds then sound goes off after a few more seconds. Also, when it shuts down there is a “pop” sound emitted. After a few seconds I push the power button and there is two “pops” and the video comes on but no sound. I shut down the unit again then power up again. On the second power up both the video and sound come on and the tv responds to remote commands which lasts about 15 minutes then no longer responds. I have replaced the power board but that did not correct the problem. Any suggestions?
