The heart and soul of my home theater system comprises of a Pioneer Elite VSX-82TXS HDMI Receiver and a Sharp LC-52D62U 1080P TV. The HD signal is being provided by my cable company using a Scientific Atlantic digital box. A few days ago, I started to notice a REALLY WIERD phenomenon!! When I turn on my receiver FIRST and then proceed to turn on my TV and digital box. The picture from my TV HD channel correspond to the crisp 1080i signal. However, if the reverse order was carried out, ie., turning the TV and digital box first and then followed by the receiver, the picture quality of the same HD channel is only 480p!!! Question - WHY??? The only sure way of getting back the 1080i quality picture is to switch off the whole system and then turn it back on again following the correct sequence. Second question - Is there another short cut? Is this something to do with the receiver, TV or cable company? Can I adjust and get the picture quality I want by using the remote of the units and if so Which one? I don't even know where to look in the operating manual?! Your help and suggestions are greatly appreciated!! Thanks in advance!
