Delayed sound on turn on from TX-NR3007b AV Receiver

I have a two year old TX-NR3007b AV Receiver that has suddenly started taking from a few minutes to several hours for the sound to come on. the unit seems to work normally if it is left on but with out a signal to broadcast. My warranty expires soon Dec. 2011 need advice.

Thank You.

Hi Randall57,
Please try doing a factory reset on your unit. Please view our blog post before doing so, this post will also teach you how to do the reset. http://onkyousacustomersupportblog.wordpress.com/2011/09/12/factory-reset/
If the reset does not fix the issue then you may need to send the unit in for service. Since it is still under warranty until December you can easily do so. Here is our blog post on locating an authorized service center. http://onkyousacustomersupportblog.wordpress.com/2011/09/13/locating-an-authorized-service-center-or-dealer/
Thank you for being an Onkyo Customer.
