I have a Pioneer Elite VSX 24TX. I have had it for almost 5 years and I love this 5.1 receiver. Within the last three weeks every time I turn it on it takes anywhere from 5-15 minutes before I am able to get sound from the unit. Once I have sound it works as normal until I turn it off. Then I have to wait an excrutiating amount of time before the sound starts. Anyone have any ideas...?
