Question about Sharp XL-DK225 Shelf System
My Sharp XL-DK225 won't turn on. When I push Power/Stand-by button the unit briefly flashes "Power On" then unit makes click sound and turns off. The timer indicator light flashes, but to my knowledge was not set. I've done the reset (P+CD1+CD5) and unit briefly flashes "Clear All," makes clicking sound, and turns off. Have unplugged unit for 24 hours, but same thing happens when I try to turn on.
I've got CDs in unit. Is there any way to manually open CD trays before I send unit for service (or trash it).
The clicking noise is usually the power supply "tripping" because of an over load, your explanation of the fault is very good and helps us in advising you about the fault...
Because the clicking gets slower it means that you have reduced the current being drawn from the power supply.
The item that is causing the over load is the item that when you plug it in or turn it on causes the clicking to start up...
Tyhe power supply is called a switched mode power supply and is usually a collection of transistiors capacitors resistors and a transformer all specially set up to make DC Direct Current and AC alternating current power for your electronics to work with.
These power supplies are expensive and no fuses are employed to make them work but a special detector circuit is installed to close down the power when a high current draw down is detected, Once the high draw down is detected the power supply closes itself down, so then it sees no more high current draw down so it starts up again and this causes the click as the internal transformer and capacitors once again start the cycle to operate to make the DC/AC supplies. So once started up the High current is detected and the power supply closes it self down and the cycle is repeated over and over....
Its a specialised job to locate the problem so its not something you can do your self without electronics training...

Hi Everyone !
We got the same problem two month ago and we fix it. The problem is drying lubricate oil from elector motor which spin the cd disk. You need to open top cover its 5 screw , 4 an sides and 1 on back. Then you see black cd changer in side. You need to open top cover of cd changer by unlock plastic clips and slide cover. Under cd holder you can fined elector motor that spin cd. You just need two drops of lubricate oil on top bearing at electromotor. My works fine right now .

Hi try this.....
Put the system in standby (ie off but plugged in) then whilst pressing down the record button and the X-BASS/DEMO button, press the PRESET DOWN (i.e.left hand one) button until "CLEAR ALL" appears, then power on your system.
This gave me some functionality back i.e. i can play normal wave CD's but not mp3 ones....
Hope this helps

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. :)
