NO
MAIN CPU may work well
q In case of other troubles
· It is very difficult to find any other trouble around LSI because LSI is connected using the bus.
· However, if the trouble cause is not in the bus but something else, it may be possible to find it by using the TEST mode.
- Push TOP MENU & PLAY at the same time and power on.
- Monitor the log using LCD on MCX- A10.
