I have an H20 with a 3LNB dish(5 LNB Install on 9/6) after watching MY HD channels from the morning till about 3pm it ok after 3pm i get no more HD channels. Anyone know why this is? Thanks guys...

Are you getting an error message on the screen or is it just going black when you switch to a HD channel?

Yeah it just goes black, no message. some get searching for signal but those are the locals which i wont get until i get new dish, and ive never gotten them. Weird tonight im getting Yankees Red sox in HD on channel 95.
