Hcd-eh15 Radio tuner works fine, but as soon as CD button is selected, it says "Reading" for 1 second then goes into standby mode i.e. power off. When try to take it out of standby mode it says "Reading" for 1 second then goes back into standby. Only way to take it out of standby is to press Standby then very quickly press Tuner before it tries to read the CD. Please help
