Marantz SR8100-DC Repair Question....

Hi, I love this site! Just recently discovered it while looking for a service manual and I didn't want to buy it... Imagine that huh?? I love the free sharing of information!

does anybody have any thoughts on an issue i'm having with a Marantz SR8100-DC. When it has Lost power, No AC, and then is connected again, it exhibits an odd display problem.

When plugged in to AC power, the display will light up, all characters, the unit will not function at all. But after about 5 minutes the display goes back to blank (no time stored) and the unit is fully funtional with no other issues.

Any Thoughts??

Thank You, Bruce
