Replacing it won't help if the Amplifier isn't able to pass the signal. Do you know what the minimum and maximum resolutions are that can pass-through the receiver?
In some cases, with DVD players, try changing it from 480i to 480p to see if that will help.
What connection cables are you using for inputs from the DVD player, and to the TV?
When Samsung TV HDMI input is connected to Sony Amplifier HDMI output there is no picture from the TV and no audio from the Amplifier. If the DVD player connected to the Amplifier is moved to the TV input (bypassing the amplifier) - the TV works. But, then I don't have surround sound. My only option seems to be to return the TV. There is no problem if I use my old Sony TV, I'll probably buy a Sony 60-inch TV.
