The SP485 is dead.

Is it a part that changes or is it really complex?

 

[Rom1]

It can be changed, look at the board; it's a 1€ chip.

ok it is located or on the motherboard it is necessary to disassemble everything to change it?
this on Green carte ? ?

 

[Rom1]

[angelo]

ok even if it does not come from there it will not be the most expensive repair to do it is worth trying I will see who can do it for me because I am not equipped

 

[angelo]

good I sent this little green card to a friend for me to change the sp485 I hope that's it and not a chips on the motherboard

Probably it’s a dead COM controller chip on the motherboard unfortunately, the games hook to COM 3 port on the motherboard for JVS to work

yes I think it must be a chip on the CM to com 3 which is dead but to find which one is dead it is better to change the motherboard?

 

[angelo]

if someone has an idea to recycle this system it would be a shame to throw it away because it is the CM which is dead and it will cost more to repair it than to buy another one?
