Question about Sharp CD-DD4500 System
I have a Sharp CD-DD4500 that I've had for quite some time and it has been a great stereo. Never abused and rarely used. It all of the sudden has the timer light flashing and if i push the power button it just makes a clicking sound and doesn't turn on, but the light keeps flashing. i tried unplugging it for a while( a week to be exact) because someone told me if i leave it unplugged it will reset itself. But that did nothing.....Please help!!

Please be aware that this a big problem on this unit. The insulator material used by sharp to between the IC's on the AV board both on top of the boards and underneath the the AV pcb is failing. This insulator is mounted to the IC and under the metal heat sinc. Remove the back and pull the AV Board out of the unit. Use zylene or alcohol and clean all of the grey insulator from between the pins on the ic and order the replacement insulators from Sharp. Most times this will correct the no sound problem. Sometimes this has also damaged the AV pcb and it will have to be replaced. The parts that should be replaced come in a kit with sharp part # PSPKIT663WHZZ. If the kit is not available the 2 parts needed are PSPAZA663WJKZ AND PRDARA216WJFW.

It's a power supply related problem. When it turns itself off, this it called protection mode. The TV automatically turns off to protect other parts form being damaged.
The most common problem is the Power Supply Unit or the Backlight Inverter Board.
You may have to take the TV to a repair shop to find out which one is bad. Paying a repair shop to replace the board for you maybe more than the TV is worth. If you let them diagnose it and you replace the bad circuit board yourself, it would be cheaper.
Here's a place I use to get parts for TVs:
The problem is the repair shop may charge you double or three times of what the part costs at the web site link above. Then, plus labor. I just want to save you money. :)

Mute + 1 + 8 + 2 + Power.
Your TV set should now say “Loading Factory”.
Browse down to “Option” then press Enter (or the right cursor button).
NOTE: The Mute+1+8+2 buttons need to be pressed down consecutively and fairly quickly. If your TV does not enter the service menu after using this combination, you can substitute MENU instead of MUTE. This seems to work for some sets. Also, the right cursor arrow also acts as the ENTER button, so try it if you’re having difficulty with the ENTER button.
To exit the service menu, hit press the EXIT button or just turn off your TV (remember not to turn on your TV immediately afterward!)

Unplug it hold down the Channel Down button and the Volume Up button unplug it for 10 seconds then plug it back in and continue holding them down for another 10 seconds then release. I had the same issue and this fixed it now I have another though *~*
