Has anyone lost any channels on thier geovision cards. I have lost 1 channel on one and two channels on another. Both appear to from nearby lightning strikes. I have surge protection on all inputs, however, I am tieing into exsisting systems with really crappy wire and installation. The lost channels just show blue screen no matter what they have connected (not "video lost" - just kinda staticy blue screens).
Anyone have any suggestions on getting the channels back or preventing this from happening again. (rewiring is impossible in most these situations or I would have done it)
