Why does the adapter plays for a sec then ejects and sais error?

Mine did the same thing. My player was primarily used in the garage and the cold weather may have caused my player to do the same thing. I just fixed my player. I removed the top cover and looked at the CD in the play position. In the upper right corner from the CD, you will see a spindle motor with a belt on it. Gently spin the motor back and forth carefully with your finger. I rotated it a half-spin in either direction, careful not to dislodge the belt. When I turned the player back on, the mechanism operated as it normally would and began playing the disc. I was able to eject and reinsert the magazine without any issues, solving the problem. Hopefully that will work for you.

The Sony website trouble code sais your Camcorder has a problem and needs a power reset.

The remedy in the SONY troubleshooting guide is copied below.

1. Turn off the camcorder.
2. Remove the battery or disconnect the AC power adapter for 60 seconds.
3. Insert the battery or reconnect the AC adapter.

You might try flipping the adapter over the other way. If that doesn't work, you might want to try putting a cleaning tape in and clean the cassette heads. The tape player will sometimes eject a tape if it cannot read it very well. It assumes that the tape is damaged. Dirt on your heads can cause it to eject your adapter because it is having trouble reading the signal from the adapter.

the lazer might not be seeing the disc properly try a disc cleaner which has nylon string on it and they clean the lazer lens

Go down further with the error message and look for the numeric code like "02 or 03 etc". If its '03' try to use another tape, to eject, open cassette door and hold until it eject(around 5 sec). If "'02" have it service by the company. If you do the job change motor bracket assembly(mode motor). Good luck.

Did try disconnecting battery or AC adapter and wait a few minutes then install power and turn on .See if it will eject

try removing the battery from the camcorder which resets the unit.
If not try holding reset for 3 sec and it should work then all you need to do is set defaults date time ect

I think you are saying you are using a cassette adapter to play the external iPod/PSP etc. and I presume the cassette plays regular tapes OK. The auto-reverse cassette player thinks the 'tape' is over, so reverses then ejects. You can try putting in a regular tape, change sides then eject. Try the adapter again. Hopefully the adapter will work in 'one' direction.

the tape is very tight
get a pen and try to loosen up the tape
100 % is the tape not the radio

I had the same problem. My unit would not eject CDs. I was able to fix it by hitting the reset button. That restarted the whole unit and reset all the settings as well, but now I'm not having any issues with ejecting CDs.
