Dear friend, I have an older model of Sharp 702 that I got a lot of use of while in college without any problems. Recently, I've tried to play a MD and got this error: “ErrorA”. I did googled the problem but did not find info/advise applicable to my machine. I've just opened the top of my 702 and manually moved the recording arm... Good news is that my 702 is now spinning a MD while making some noise. Bad news: “UTOC ERROR”. This “UTOC ERROR” seems similar to problem on your unit. Can you please describe in detail how to lubricate the mechanism? Thank you, Ilya
