I just recently have had some "weirdness" with my TV. First thing I noticed was an issue with the remote. The input button seemed to stop working on the remote. The input button on the TV itself works, as does using an IP remote. Playing with the remote a little more it seems that I have a few buttons that have gone out, all in a row. From left to right those buttons are: Mute, Volume UP, Channel UP, and Input. The 4 buttons above those are apparently dead as well: CC, AV Mode, View Mode, and Flashback.
While it seems odd that a portion of the remote would up and die, I noticed another odd behavior. The LED power indicator "^", now doesn't go out when the power is off. Yes, I was able to go into the settings and turn it off, but I swear the normal behavior was that it was lit while the TV was on, and it went out when the power was off. Now it just stays on unless I go into the settings and disable it, then it only lights for a few moments when you hit the power button.
It's especially odd that these seemed to have happened at the same time... Anyone seen anything similar?
