Question about Sony STR-DE445 Receiver
Your unit should hold settings for at least a week with the power off. Inside the unit is a backup power supply capacitor that maintains the preset memory. This part will be faulty and require replacement. It is not a user serviceable part, so if you wish to fix the problem, you will need to take it to a sony repair guy.
