I have a Panasonic 720P 50" Plasma. Had it for a few years and never a problem.
I used to be set up with a onkyo receiver and component cables.
I recently purchased a new Yamaha RX-V475 receiver and ran the direct tv hd dvr and ps3 into the Yamaha and then HDMI out to the Panasonic TV.
I have tried to change the settings on everything to make sure the resolution is set to 720 for playback devices.
I started noticing a pop sound which sounded to me like it was coming from the TV, then the picture resets by going black, then HDMI 1 comes up on screen and then the picture returns.
I went asked the guys at best buy what they thought and they said it sounds to be over heating and resetting itself, a faulty unit and advised me to return it. which i did for a new unit.
now the new unit does it also. somewhere there is a setting not right, it cant be the receiver - it appears to be working fine and I dont get the problem with the direct tv signal, only when using the ps3.
any ideas? should i change the hdmi slots on the av? should i try new hdmi cords?
everything worked fine before so i ask what has changed?
1. The HDMI ports on the tv were never used, maybe ones bad?
2. the receiver but i think its working fine
thanks for any light you can shed on this.
