Sharp system has blinking timer light but doesn't work

How can I regain control of my Sharp CD MPX880 System

My Sharp mini component system cd-mpx880 has the timer light flashing 1 long and 4 short flashes. The system is totally unresponsive to any button selection either manual or remote.

    thanks for the suggestion. I actually thought about this possibility and after unplugging the system I figured (incorrectly) that perhaps it would 'freeze' with the power off. So I plugged it in again last night in the hopes that the programming would 'run its course'.



    Interestingly, the Operation Manual has a procedure for "resetting" the system but that doesn't work either. In fact, even with your insights, it seems odd that the display screen isn't functional either. Could be a system defect, no?



    I'll let you know what happens tomorrow.

    I've tried disconnecting the unit for over 24 hours and when it was plugged back in it still had the same problem.

    Does anyone know the meaning of the 1 long blink followed by 4 short blinks of the timer light? Incidentally, there is no information lit up on the display screen either.

    thanks. I brought the unit into an authorized Sharp service center since I believe the work is beyond my own abilities. Your assessment convinces me that is the right course. Incidentally, the unit is only two months old and is still under warranty. thanks again.

The control board is most likely faulty. It will have to be tested. You can use a test light, and an ohmmeter.

You have by mistake and pre programmed it. this activates the timer so it won't do anything until it reaches the date and time it is programed for. And does whatever it was set to do on that date. The best way to fix is. Unplug it and leave for 24 hours before plugging it in again. The off buttton probably doesnt work but if it does still unplug it because power to the unit will keep it programmed. The reason you will need to leave it for 24hr's is it may have a a backup charge in the system good enough to keep the setting's for that long. You may be able to plug it in sooner but run the risk of it still being programmed and not alone the problem being unsolved it will have backed up more power and you will have to wait again. Cheer's

    It's hard for me to advise you further because it's probably an internal fault so it's best to get someone with tools and knowhow to fix it.

Short circuit protection circuit is ON. There should be a fault; probably to its audio output section circuit. These blinks shows that. Contact any service technician.

How to remove timer


If the unit is controlled by a remote, the symptom you are experiencing could be cause by a function only available on the remote. I discovered this with my Yamaha 5-CD disc changer. However, my unit doesn't have an integrated Stereo. Your unit may mean that the remote handles more features. Search for a button that says MODE or AUX. If you still have the User Manual with the system, check to see what these buttons describe as controlling which features. Check back with me.
