I'm using a Sony STR-DH510 receiver with my Samsung series 650, connected via HDMI. One day I removed my Direct TV DVR from the reciever and when I tried to watch a DVD the TV would not get a signal from the DVD player. I hooked the DVD directly to the TV and it worked fine. Reconnected the DVD through the receiver again ans no signal. Samsung sent a tech out and he did a reset and it worked through the reciever again. He would not tell me how he reset it...? Now I switched some components around again and sure enough it will not work through the receiver again. What did he do...? How can I do the reset he did?
