Panasonic SA-VK680 Won't power on. Ac in light is on bit nothing happens when I press any buttons. I have tried a memory reset the lights and dotted lines come up but it doesn't fix the problem.

I took your advice I unpluged the unit then held the power button in then pluged it back into power outlet the unit came on. There is one thing I might add I had to do it twice before the unit came on. Now how long will it work? Who knows
