dooleyb 0 Posted August 30, 2004 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) Share this post Link to post Share on other sites
Thomas 0 Posted August 30, 2004 First rule of thumb. No surge protector you can buy will protect against lighting strikes. The one people that come close are power companies and even then they are ment to be one off. Share this post Link to post Share on other sites
