Hi there.
I have a Samsung PN42A450 plasma tv paired with Samsung's HT-TZ512 home theatre system.
I have my connections set up as follows:
Cable box --> component cables to --> TV
Cable box --> optical cable to --> Receiver
Receiver --> HDMI cable to --> TV
When I turn my tv off, the receiver turns off with it as it should, however it never turns on when I turn the tv on. Also, if I turn the tv on and immediately turn the receiver on, the receiver only stays on for a second and then disconnects and turns off. I have to wait about 30 seconds after the TV is on to power on the receiver so that it will not turn itself off..
Anyone have any ideas? I have not called Samsung yet because I'm totally dreading it and hoping I can find a solution on here instead...
Any help would be really appreciated!
