Two days ago my stereo started turning itself on. When I turn it off, it will click off for about 20 seconds and then come on again. It still functions like normal when I want to play CDs or listen to the radio, but it will not stay "off" unless I unplug it. It continually will turn itself on, over and over again. Any advice on how to fix this? Thanks!
Hey there, you actually need to press the Stop /-DEMO Button when the device is doing the demo mode...it will take about 8 seconds and it will display "DEMO OFF" and turn off. This procedure needs to be run everytime there is a power failure OR you unplug it from the wall.
Pressing the Stop /-DEMO while it is on will cause it to start the demo while it is running!

Generally speaking, an amp attempts to protect itself from heat, shorts, overloads and operator exuberance by refusing to turn on or stay on.
Overloads can be from excessive periods of high output or marginally low impedance loading by the speakers; and shorts would be wiring issues or a speaker blowing up.
You should be able to feel if it's hot. WHY is it overheating? Make sure it has sufficient ventilation on all sides and that vent holes are not blocked by dust balls. Ensure the fan (if equipped) is running as designed (some only operate on demand). Clean dust and debris from it.
If the amp comes back on after cooling, you're lucky. They only have so many self-protection cycles in their lives so continuously resetting or cycling their power without addressing the cause can do more harm than good.
If it protects immediately on a cool power up you should disconnect the speaker connections and try it 'naked'. If it comes up then diagnose which lead(s) are shorted. If it does not come up the problem is internal and should be left to an experienced and competent hands-on tech.
Check for loose speaker connections at the speaker as a root cause for intermittent shutdown.
Un Plug It for like 10 to 20 seconds and plug it in it should work it happens to me all the time if it contionuls check the speaker wires and see if the wires are toching together that will be the problem to
I am afraid you have a bad power supply capacitor inside this unit. if you do not know how to check the capacitors, you will need to take the unit into a repair shop. Depending on how expensive this unit is, will determine if it is at all worth repairing. Good Luck
It certainly sounds like a defect and I believe would qualify as a warranty repair. Talk to the store where you purchased it to see what their warranty procedure is before it is out of warranty, which can be as little as 90 days. Good luck.
