I have got a Philips 42PFL7406K TV.
There are two HDMI deviced connected by cables to this TV.
With current configuration, when i swtich of my TV and turns it back on, the active channel will be the last one before i turned it off.

However, I know that i can set it to start up with fixed channel(for example: every time i turn it on, it will be on HDMI1 channel).

I really hope you can understand me and give me a solution to this

Thanks in advance!
