EJECT MESSAGE ON SONY MHC-RG66

[faksolmic@yahoo.com]

Hi All,
Greatly confused and really wish somebody could help me out.
I've working on a Sony deck player for the past two days and could not traced out any fault in the system. The message "eject" will appear anytime you plugged in the cableof the deck, if I power on the deck, the disc tray will turn for about 7 times and go to standby and finally to stop position.
The model code is: SonyMHC- RG66.
Thanks for your Assistance.

Michael
