Question about Hitachi 42HDS69 42 in. Plasma Television
**This is actually about the Hitachi 42HDF39 model which wasn't listed in the product list.**
I only have local channels which I receive with a powered indoor antenna. Last night I was watching tv and switched to a certain channel and it acted as though it couldn't receive the signal so I tried to change the channel to something else but the tv had just ''frozen'' up. The ONLY button on the remote and/or tv itself that would work was the ON/OFF. This has never happened before when the antenna seemed to have a reception problem. The ONLY thing I could do was turn off the tv and the antenna just so I could access my av inputs and all that, which I tested and all are working just fine. I tried several ways to get around this problem but had no luck. I called 1-800-HITACHI and the rep was unable to help me after a number of possible solutions. This morning the problem was still there so I tried something different: I shut off the tv and antenna, turned the tv back on, accessed the DTV menu, and locked out that channel. When I turned the antenna on it acted like it simply couldn't receive that channel and I was able to change the channels and even use the other buttons as if nothing were wrong. If I were to unlock that channel and attempt to receive it, the problem will come back. By the way, the other channels are working just fine. I don't understand how this one certain channel issue is causing the tv to completely freeze up.
On another note, I did lose another channel about a month ago and I haven't been able to receive it at all since then. My next door neighbor also uses an indoor antenna that's weaker than mine and he is able to receive this channel. It was working just fine until we had that ice storm that ran through the eastern coast so I assumed their tower was down, until I spoke with my neighbor and discovered that I was wrong. Is this possibly related to my current issue? I didn't have the current freezing problem when I lost that channel though and attempted to receive it. Very odd. Any ideas?

Digital receivers whether external to the TV (converter box, satellite) or built in are digital processors(computers). Just like computers there are times when they freeze up. This can happen if the data stream is corrupted too much to render the picture, but enough signal to lock. The processor attempts to "wait" long enough to gather enough information to begin. Just like computers, these need to be re-booted by turning on or off and sometimes unplugged and plugged in. You have either too low of signal quality or too high of signal strength, which is a problem with digital receivers.
