Question about Sharp CD-BA300 CD Shelf System

Open Question

My Sharp CD-BA300 CD player won't open and displays "ER-CD 11". "Protect" is not displayed. Anyone have any ideas on what's broken and to fix it?

I've tried the only troubleshooting advice in the manual (to "clear al") but that did nothing. This started shortly after a big storm that caused several short power outages.

Cd tray will not open er cd11 code

Just talked to customer service at Sharp because I had same problem with my CD trays getting stuck and would not open even if they had cd's in them. He walked me through resetting the cd system. First have unit plugged in but in standby/off. Then press the open/close button, the stop button and the CD button all at one time(beside holding unit still to keep from sliding) till the display flashes CLEAR ALL and then let go and turn unit on and see if it solves your problem. It solved mine but I did write down instructions to make sure if it happens again I can use it again. Good luck, Helen

Does it open when you print a Z report? The most common problem with these was either the drawer wiring or drawer solenoid failing.
If anyone needs more information, the Sharp ER-A410 and ER-A420 manual is here:

Sharp CD-BA300 stereo system went into Protect Mode. When I power up all it does is display PROTECT. How do I clear it.

1 suspect speaker defect
2. suspect wiring defect ensure all your wires are connected up properly and your speaker are in good order
3. suspect that the cooler fan may be blocked and the system is overheating. use vacuum cleaner on air vents to remove dust.
4 see specialist as this product maybe defective.

PROTECT on display

Dear petfresh,
Please switch off the system, remove the speakers wires from the system and switch on the system. If system gets on then the speakers or speaker wires are defective.
Output IC is Audio out put IC.( Integrated circuit)
It can be fixed only by service technician at service point
