I replaced the LCD panel in my home theater system this morning with a new Sharp Quattron LCD. The problem I am having is that when my Blue Ray player is connected directly via HDMI, the panel displays correctly. The player is a LG BD390. When the player is connected thru my av receiver, an Onkyo tx-sr606, the lg boot up screen displays properly (480p) but 1080p wont display. I have a second blueray player, a samsung unit, that does the same thing. I have an old Toshiba HDDVD player and it works thru the av receiver (1080i) and so does my Directv HD receiver(also 1080i). All are connected with HDMI. I have tried different hdmi inputs on the panel to no avail. Everything worked properly yesterday with an older Sharp Aquos 1080 p panel. Suggestions?
