This is listed for parts are not working, I do not have a power cord for it and so I have never tried to turn it on. I don’t know if either one of these items work. If I do come across the power cord I will test it and will then update the listing. All the dials do turn and the buttons do press and spring back out. Some of the buttons do press in and hold and then need to be pressed again to spring back out and other spring back out immediately. Please use pictures to help determine condition. The buttons on the microphone also press in and spring back out. I will put the cover back on and replace the screws as best I can.
