    My CD player is an Ayre Evolution that is 13 years old. The warm up light is off and I can't power it up.

    I have tried unplugging from unit, wall, etc. Looked at manual and there is no trouble shooting section.

    Now I have had some trouble with this thing that I probably should have complained about long ago, but I was always able to overcome the issues and let them slide.

    The most pertinent to this problem is that I noticed it would turn itself on automatically whenever the house experienced a power outage. This includes little surges. It took me awhile to figure that out as I used to think I had somehow forgotten to turn it off. Coming home from a vacation one time horrified me to think I could be so careless. Once I learned that I would unplug it whenever I was going to leave home overnight.

    The other issue was loading a CD into the drawer. Unless you center the CD and then push it back to the rear of the ring, the CD will not read. After a long time spinning and searching it would just quit and usually pop open the drawer.

    Other than that, it's been a solid performer.

    Does anyone have any ideas? Could it be a simple fuse?

    It will have a fuse, so start there.

    There's no harm in leaving it turned on or that it powered up after an outage.

    Unplug the transformer from the main
    Board. Switch on and check voltage.
    I measured 15v on my Nakamichi.
    If transformer is ok. Then ,next on pcb
    Board you may find 2 thermal fuses.
    They look like transistors.
    Simply check for continuity.
    Mine had blown.
    Replacement restored my Nakamichi
    To full.power.
    No doubt it won,t the same for your player. But, you can see that sometimes
    Methodical working can pay off.

    Try another power cord and another outlet. It's possible the power supply within the unit died. At that point, it probably would cost less to buy another CD player than it would to pay for a new power supply and the work associated with making the new one work.

    Not necessarily. There are repair specialists. A few if us believe the older machines were nicer sounding.
    I guess what i am saying is if you have gotten used to the sound of your player
    Then fix it!

    find out how much the repair will cost and weigh the options...either way you will wind up with a CD player again.

    There is a fuse in the power receptacle on the back. You have to pry out the bottom fuse box with a screwdriver. If it is blown (check with multimeter), you can replace it with the correct value and see if it blows again.

    (What else do you see that you can fix?)

    This was especially helpful, thanks to all for chiming in.

    When I take to shop I will be able to suggest fuse change.

    Is the fuse right where the cord comes in?

    The fuse outlet is something that can be user-serviced, although being blown will likely indicate an internal fault unless you had a power surge.

    There might be an extra fuse in there also.

    This is what's on the back:

    It makes no sense to repair ,but.....
    They are for the most reliable,
    As well as repair, a few new caps etc can transform. Howvabout a new clock
    Or tube output stage.
    A popular mod is to by pass op amp and feed output ftom DAC into tube stage.
    Impedances are perfect , feedback is removed and output sime 6 DB less

    Unfortunately, most CD/SACD players will eventually end up like this.

    Unreal. Thanks so much for your help!!! We have surges all the time, especially in the summer months with all the AC running.

    A dire situation is now looking up.

    I will report back once I either solve problem or get more bad news.

    The fact that you said it turned itself on occasionally means the power switch is only switching DC and not AC. Basically the unit is always "on" and consuming power even when you turn it off. Most are set up this way, otherwise it would be impossible for the remote control to power the unit on and off. The power supply being always on could lead to premature failure of one or more components in the power supply section. The fuse was an obvious place to begin, past that, as someone mentioned is the power transformer, a bridge rectifier of some type, a voltage regulator, and filter capacitors (the large round blue ones you see in the photo).

    Power supply problems are typically the easiest to troubleshoot, since they're not complicated and use basic components, easily found. If the unit shows no signs of power at all, in all likelihood the power supply is the issue. Any average tech should be able to troubleshoot and fix it, possibly even without a schematic.

    Dude! You're the Man!

    I finally had the time and patience to investigate. I really didn't feel like moving the rack out of the black hole it resides in.

    Slid the little drawer from under the plug and found an extra fuse. Installed and wallah!

    Sounding real good.

    Thank you so much once again!

    It's time to send to a tech or replace it.

    Obviously you did not read my last post.

    It's working now.
