Battery Power works, AC does not work

My Kenwood DPC-472 is consuming lots of AA batteries, so I thought I would try to run it via the AC adapter to save batteries.

I removed the batteries and plugged in the adapter to a 120V socket and into the AC plug on the unit. I inserted a disk, made sure the Hold switch was not switched on, and pressed Play. 00 flashed on the screen, and the unit turned off. I replaced the batteries, keeping the AC adapter plugged in, and got the same behavior.

When the AC adapter is plugged in, it appears the device defaults to the AC power.

I unplugged the AC adapter, and tried again, just on batteries again, and the CD played without issue.

Are there connections I should check to make sure the power is getting through?

I ended up opening up the device, unplugging the power source plugs from the board (AC and battery), and then plugging them back in again, making sure they were fully seated. I managed to play a CD with just the AC connection plugged in, and it continued to function after I plugged in the battery connection. I think the connection had loosened over time (and falls). It is running now.

Make sure you're using the correct AC adapter and the adapter itself is working properly. Essentially, the AC adapter is a step-down transformer enclosed in a plastic case which converts 120v AC to 12v DC power. You could try to find something similar to test this adapter with,,, a small DVD player, radio, etc. Also make sure the connection from AC power to the DC unit is nice, snug, and clean. I hope this helps. One more thing. There may be a small reset button somewhere on the unit. If so use a pen. paper clip, etc and gently push the reset button. Again, I'd like to know if this helps or you find another resolution. Thanks.

I am using the AC adapter that came with the device. I ended up opening up the device, unplugging the power source plugs from the board (AC and battery), and then plugging them back in again, making sure they were fully seated. I managed to play a CD with just the AC connection plugged in, and it continued to function after I plugged in the battery connection. I think the connection had loosened over time (and falls). It is running now.

Next step: get the AC plug able to recharge the rechargeable batteries. I just bought new batteries, but could not find the specific kind specified in the user manual.

Ok. So I assume you have 120v at the receptacle. If so, is it ground fault protected upstream and if so is it possible it may have tripped?

And of course if it hasn't tripped you would have power at the receptacle. If it's running now that's great! Be aware that soldered connections on the board can become corroded and as you said loose over time. If you're comfortable using a soldering iron and a little flux you could apply a light tin coat to the iron and re-solder the connections.
