Samsung LCD TV automatically switches inputs

Here we go again. Why is a computer geek posting blog articles about problems about a Samsung LCD TV? Because I figured if I’m experiencing this issue, then someone else, somewhere in the world is probably experiencing the same issue. We started experiencing a very strange problem and it started happening all of a sudden. The problem was that my Samsung LCD TV automatically switches inputs for no reason! We just be sitting there, watching a movie and all of a sudden the TV would switch to another input, usually to over the air and then start scanning all the channels like it was performing a first time channel setting when you first connect your TV to your cable box. Worst of all, I was unable to switch back to my HDMI input so that we can finish our freaking movie. Why is this happening to me?!

I thought it might have something to do with the Anynet configuration. That is the mechanism that automatically scans for any Anynet devices connected to your TV like (Chromecast or Amazon Fire TV) so that when you Chromecast something or press the Amazon Fire TV Stick microphone button, your input on your TV automatically switches to the correct HDMI input. But after an hour of messing around with the Anynet configuration and even after turning it off completely, the problem was still occurring. I also made sure to update the TV firmware to the latest version. No dice.

I even changed the batteries on the TV remote but that didn’t did anything either. I figured the TV was busted. After all, it is about 7 years old and I kept reading how other Samsung TV owners were experiencing the same exact problem. The way they fixed their issue was to replace the main board. I don’t know about you but that sounds expensive to me. So I tried once last thing and it fixed the problem! You won’t believe how simple it was. I removed the batteries from the Samsung TV remote control. That’s it. Apparently there was a problem with the main board and the communication with the remote control. Since I hardly ever used the TV remote control, it was no big deal to remove the batteries from it and tuck it away in a draw.

With today’s cable and satellite remote controls, you can program them to change the input and do everything the TV remote could do. Hell, even if you are one of those people who can’t figure out how to program a TV remote control if your life depended on it, the worst case scenario is that you have to get up and manually switch the inputs on your TV.

Unbelievable! Just remove the batteries from your Samsung TV to work-around this issue especially if you don’t want to spend a bunch of cash replacing the main board on your otherwise perfectly working Samsung TV.

Here are the particulars of my setup:

TV: Samsung – Series 550
Model: LN40B550K1FX2A

I hope this helps someone out there. Good luck and thanks for reading.
