This is my TV1 remote, 5.3 I think. In the last week or so it's very slow to switch from controlling my surround to the TV. I hit the SAT button or the TV button and it won't turn the TV on. Sometimes takes me 2 or 3 times to get the TV to power on. Same with controlling the TV volume. It seems to control the surround and the 622 without issue. I'm not getting the weak battery message. TV is a panny plasma.
