walkman sony f701c

Please tell me why fm radio frequency start to 76 and end to 90 mhz. how to change on us or uk frequency ??? problems on chip? circuit 1-629-443-13 cfx621
i changed the wm 707 radio circuit but the situation is the same.

 

please i need schematic japanese radio circuit

 

Did you try to simply move that resistor to UK?

 

tried nothing happened. i think it is a way to change with button enter band etc

 

Ok I see there is an enter button on the board.

If you press and hold the enter button while in FM does it display area ?

or the Press and hold the band button

 

You can hold enter
1. Go to select preset
2 hold more go in auto search
3 band button change to fm tv am

I try to hold more button together asd enter +or - Nothing
And in service or operation manual there is not information about it

Walkman’s famous technician told me that it is a reset of chip impossible to fix in this case
