My TV is about 10 - 12 years old (I guess it's a tube TV - it's not a plasma or LCD). My FiOS remotes have worked flawlessly, but now they only work intermittently, or only some remote control functions work.
For example, sometimes the Mute control wil work, sometimes not. For the past couple days, I cannot switch the TV Input choice to watch DVDs. I can no longer turn the TV set on using the remote.
I replaced battery remotes; cleaned the surfaces of the TV set; and tried three different FiOS remote devices.
Is the problem possibly a component on my TV, such as a sensor?
