Check your cables, a slightly misaligned or stressed HDMI cable can cause the problems that you are experiencing.
On my Sony TV, I take the V6 out of standby, by pressing the TV button on the V6 remote and then take the TV out of standby, using the standby button on the V6 remote.
Some TV's look for a signal from the V6 box (on HDMI port 1) and if they do not detect it with a preset time period, only a soft reset of the V6 box will cause the signal to be sent. A simple solution to this is to plug the HDMI cable from the V6 box into HDMI port 2 on your TV.
You can't learn anything from a mistake until you admit that you've made it.
