20 Most Recent Sharp CD-DD4500 System Questions & Answers

Any audio device that has a headphone output can be adapted to feed an RCA cable pair for
standard stereo to any audio device with a standard RCA input (except one labeled "PHONO").
Get a cable like the one described here: http://www.monoprice.com/products/product.asp?
c_id=102&cp_id=10218&cs_id=1021804&p_id=665&seq=1&format=2
and connect it into any available analog input EXCEPT one labeled "Phono".

Shorting out? If they short out they will never run again.

Generally speaking, an amp attempts to protect 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.

Check for loose speaker connections at the speaker as a possible root cause for intermittent shutdown.


Try it on outlets that don't have any problems. If THAT works get the L/R outlets looked at by a trained electrician.

sony makes the cheapest cool lookin **** expect this in the future my friend replace tis a shame i know

this is a common problem with this unit the main thing is a low grade capcitor that the manufacturers used which is known to discharge all of its power at once which it recieves a high signal output and tells the unit to shut down the solution is very technical but basiclly you gave to install a higher amp capacitor.

I am uncertain how to present this to you. Press the ALARM ON/OFF button to turn off the alarm. If you want to turn on the alarm again, press the ALARM ON/OFF button once more. Detailed instructions regarding the controls can be found in a manual I think available at the following location: Sharp Alarm Clock Manuals and User Guides PDF Preview and Download (all-guidesbox.com) I don't have a guide to the internals of this clock but here is a tear down of a similar model if you are game to explore the workings. You could go through that and maybe get an idea of how the systems work together. If you are unable to fix the problem, you will find the contact details for Sharp support in the manual.
