Hi and welcome to JustAnswer,Thank you for the question and your patience. Should you still need assistance for information purposes only...Initially, have you tried another outlet? ...and please confirm "SLEEP" function is not enabled nor is it displayed.
The Sharp CD-DH950P will auto power off if it detects 'no signal'; i.e. no radio station, audio source has stopped.
Does the "...shutting down after 15 minutes..." happens when just listening to a particular radio station? ...or listening to CD, USB or TAPE ?
Thanks for getting back and interesting!
Is the front panel's "TIMER" indicator lighted up?
Unfortunately, no. The auto-power off is hardwired to the system.
Ensure that the Sharp is connected to antennas or if yes, try better antennas. Another try is to relocate the CD-DH950P or even just re-orient hot it is positioned. In some instances, merely using another outlet may also help.
Please post back results / observations of the above once tried.
Hi again Gail,
Sorry but I have no more ideas to propose. Hopefully another member can provide an alternate approach or even a second opinion to your concern. The question would be re-opened as I would be opting out.
Still, good luck with the Sharp.
