Wrongly inserted cd in an AIWA CA-935M

I was able to find the manual for that model, which included a series of tests for the CD trays. Perhaps if you ran through them you will be able to get your CD out. If not, please ask for additional help.

Hello Reinaldomd, your failure originates in the extraction system of the CD
I enclose a work that the people of Tecnicoreparacion have done, in which they describe the fault and give solution to it
I hope you solve the problem

Try to use an old CD...and insert it under the stuck CD...push in slightly while using the eject button...on may models this will release the stuck CD...Hope this helps.

Somewhere on the front of deck there should be a small pinhole just big enough to fit the tip of a pen push it in either pen or Sharp object. It should force it out.

try to turn off your cd player then turn it on again then press eject if this not work if your unit has warranty send it back to nearest aiwa center to reaper it or replace it or give your money back just bring your original recipt

there is a small hole in the front panel, straighten out a paperclip and push one end into this hole until the tray releases.

You will probably have to disasssemble the unit to get it out.

I SUSPECT that a little drive belt for the eject mechanism has failed so it cannot eject the CD.

When you press Eject CD button, do you see CD display blinks as if its preparing to be ejected? If its true then eject switch is working and cd mechanism is stuck, requires service. Also check loading belt in mechanism.
And if unit shows no response on pressing CD Eject button then switch is bad, replace it.

They may be heldin by the handle, or tabs that you either need to push or pull on the sides or bottom of the unit.;

HI, this is totally main board failure. try to unplug for 3 minutes then, plug back in after the three minute shutdown. if this continues, replace the main board(control).
