Sharp SD-AT1000H We recently got this system, but we didn't get the remote. When we try to power up the unit, it will power up and shut off right away. Any idea what the problem might be?

I had this problem with mine and found it was very sensitive to anything being placed on top of it. Even dust on the top surface would set it off, so cleaing off the top sometimes helped. Eventually I took the top off and there is a piece of metal that contacts with the case. I bent that back slightly and it seemed to do the trick.

I am having the same problem...the manual says to un-plug the unit for five minutes and then plug it back in to re-set, but that is not working either...

Turns off


Based on your post description, a short was introduced to the output of your system (wires touched). Since you were playing at a high level and the touching wires represents a 0 ohms load, there is a strong possibility that the power amplifier burned (too low a load at too high an output). The burnt component then represents a failure. When you try and power on the unit, it will go to its built-in diagnostics/initialization stage where it will sense the fault and thereafter go to auto-protect (shutdown).

Corrective measure would involve opening the unit and performing diagnosis of the circuitry and components check. Since these call for familiarity with electronics, use of a DVM and a soldering iron, perhaps your best course of action would be to seek the services of a qualified audio technician. Should you venture a do-it-yourself, you would need to concentrate on the audio amp, specifically the finals or outputs which could be a large power IC or a MOSFET pair. Determining which is at fault would simply be removing suspected component and verify that the unit will power on albeit any sound output. Of course the usual precautionary safety measures apply when working with live units.

Hope that this be of some help/idea. Pls post back how things turned up or should you need additional information.

Good luck and kind regards.

Stereo turns on shuts off after few seconds

This is a bad power supply. You have to do some serious work at the component level of the unit to fix it.
