Hi, I have a Marantz SR7500 receiver connected to a Samsung LN52A650 lcd tv via component cables. I have an old Bell ExpressVu receiver connected to the Marantz via svideo. When I first power everything up all I get is green screen? I have to wait 5-10 mins then power the Marantz down then back up and the picture comes on. While the screen is green I can't get the menu of the Marantz to come up, so I figured the problem is with the receiver? Has anyone seen anything like this?
