in the mornings when i turn on the tv and push the select button i am stuck watching that channel for a few minutes. it will not respond to any signals from the remote. which is weird since it will respond to the select button when i push it to get off the standby screen. it has been like this for as long as i have had it so i thought it was just one of those things. now it seems to take longer to respond to the remote. anyone else have this problem with their 722?
