Power Off

Hello I have a Realistic sta-235b receiver and everything works great except when I try to turn it off it stays on and I have to unplug it?? Can anyone advise? I have limited knowledge of these and I don't want to damage anything. thx in advance

My Denon AVR 15-13 5.1 receiver has developed the habit of randomly shutting itself off causing the power light to blink red at an interval of twice a second. I disconnected all the speakers and peripherals, even the subwoofer, but it still keeps shutting off. Sometimes it works perfectly, all...

Here is a good fix for it, I made a YouTube Video that doesn't require rolling the driver back https://youtu.be/Xjat1l5tGz0 It's just a setting in the device manifest.
