This item has been stored at home and has not been used for a while. I have confirmed that the main unit can be powered on, but the AC adapter seems to be faulty, and the power sometimes cuts out abruptly. Also, the three-color AV terminal seems to be malfunctioning, and the video may not display. I have not been able to verify the software loading. Due to the above, I am selling this as a junk item. Please purchase only if you understand that this is a used item. m(_ _)m
