Sony SL-T30ME hall effect part number?

Hi,
When I turn on my vcr (Sony SL-T30ME), the drum and left reel motor starts to spin. There is no tape inside and it does not accept tape to load. At this time, no any buttons work, only way to stop vcr is to push power on/off button 5-7 secs. As I search the possible reasons for this issue on youtube, the hall effect sensor generally cause this type of problems which is located under the head drum. When I checked that part, there is some rust around there. I tried to clean with isopropil alcohol and remove the glue as much as I can but it did not work. I think the only way is change this hall effect spare part. So, I need the part number or any equavelent part that may work for this. Any help would be appriciated. Thanks.
