sharp component system - No output
Hi guys I have a sharp CD-DK4500 which has no output to the speakers
If you unplug it, and let it sit, then plug it in, it will work fine for maybe 10-15 seconds and then you hear a click inside the unit and the speakers stop. The click suggests to me something is shorting? And leaving it unplugged lets the short un-do itself? Or something, I dont know which is why im asking in here, any ideas? |

The click is coming either from the standby relay, or the output relay, and indicates that the unit is either protecting itself - possibly from the effects of a defective speaker - or is protecting your speakers from a defect within itself. First move is to disconnect all speakers, and see if it stays powered then. Arfa |
