The issue(s) started with the WiFi dropping out, periodically. I down loaded and installed the latest firmware. Now it won't stay connected more than a minute or so. The wired network connection worked up until a week or so ago, now it won't connect or only connects for a short period of time before dropping the connection. To go along with this, the smart remote loses the ability to change volume, or any other function other than off. And that may take a while to get it to turn off. After turning it back on, the remote may function for a while again, or not. (yes I put new batteries in it)
I'm wondering if I need to replace an internal component in the TV? I'm sure I can replace it myself, I'm just not sure what I need to replace.
