Hello everyone
My old controller was LCD broken. so we replaced it with the 2nd hand one from Ebay
the model are exactly the same, But the new has no "Retrace" function inside
although we set all parameter completely same as the old it still not function.
How can activate it? in the manual said activated and deactivated by RETRACE [M5051] , What 's it mean? I have no idea about it.
Checked the installed option in + / diagnosis /configuration / software config /
there has no Retrace option in that list.
thanks
LYQ
