Question about Sharp Audio Shelf Systems
Sharp cd-xp200 bookshelf stereo has no sound coming from the speakers on both channels. The tuner and tape drive and cd player all operate and all controls seem to be functioning just no sound.
It definitely sounds like it took a surge. yhe Power Amop IC in those things are pretty sensitive. Any decent repair shop should be able to repair it for under $125.

if there are no additional speaker jacks on the back of the receiver, then no; at least, not easily.
What ohm are the speakers?

Testimonial: "WE took the Sharp unit back. Not only could you not hook-up the remote speakers, you could not shuffle as advertised. Thanks for your help."

Make sure the speaker wires aren't shorted together and that they are not freyed or cracked...the unit is in protect due to it's internal circuitry sensing a shorted output condition...this is in place to protect the unit should the speaker wires become shorted together. You can remove the speaker wires entirely and then turn on the unit to see if it comes on...if so then I would look at each wire carefully to make sure they look good..of course if the unit comes on and the wires look good then you may have a bad speaker component...Now, if the unit stays in protect after you unplug the speakers, then the unit probably has a blown audio output stage inside the circuitry and will need to be serviced.

Since you all ready tested the wiring and speakers, one or more audio output ic packs have shorted and will need to be replaced, you will need a technician to check the extent of repairs that will be required and I suggest an estimate.

Generally speaking, an amp protects itself from heat, shorts, overloads and operator exuberance by refusing to turn on or stay on.
Overloads can be from excessive periods of high output or marginally low impedance loading by the speakers; and shorts would be wiring issues or a speaker blowing up.
You should be able to feel if it's hot. WHY is it overheating? Make sure it has sufficient ventilation on all sides and that vent holes are not blocked by dust balls. Ensure the fan (if equipped) is running as designed (some only operate on demand). Clean dust and debris from it.
If the amp comes back on after cooling, you're lucky. They only have so many self-protection cycles in their lives so continuously resetting or cycling their power without addressing the cause can do more harm than good.
If it protects immediately on a cool power up you should disconnect the speaker connections and try it 'naked'. If it comes up then diagnose which lead(s) are shorted. If it does not come up the problem is internal and should be left to an experienced and competent hands-on tech.
