 Only yesterday my neighbor came over to ask me to look at an outdoor light needed repair. It was wired into a sensor, and she figured that it couldn't be that hard just to replace the whole unit. Good thought, but not for everyone. By the time that I was in on the deal, I had to first figure out just what happened during the last fix. In short, it would have been better in that case for the person to ask someone at least with experience to look at the situation. Not to go into detail, but the situation was FUBAR and didn't need to happen.

@Carlsbad. Thanks, I'm probably in the 90% that couldn't fix it. Then I surprise myself every so often.

 I just remembered an Apollo CDP player that I bought having the same problem. The trouble had occurred in shipping. In this case, all I needed to do was loosen the screws holding the faceplate, and then realign the faceplate to the proper position. I hope that you might have a similar situation. 

 And sometimes when this happens, you can check the alignment by pushing the button up as you push it in. Of course, it may be sticking in any number of other possible positions, so try each direction to push the power button away from the sticking point as you push it in. Worth a try.

Thanks, I just might give that a try. There are 4 screws on the face plate. if that doesn't work I take it into a shop.

I had the same problem with a Cayin integrated. I thought it probably needed a new switch. I took it to a local tech, it turned out the switch was just out of alignment. He wanted to return it to me at no charge. I insisted on paying a minimum bench fee.
