BA and LA chip functions?
BA and LA chip functions? –
I'm sure many people are as curious as I am - but what do the above chips exacly do, and what are the symptoms if they're blown?
From all the posting's ive read the LA controls the tray movement and the BA controls the focus and the movement of the laser on the sled.
I"m under corect here though - anything else they do?
From my experience, the LA is used for focus and tracking control, as well as tray fuction.
The LB is is used for spindle motor control and switch limiting. (Limits the travel distance of the laser head).
But if you mean what are the differences between the LA an BA's, then they basically do identical functons.
Thanks - thats the info I was looking for.
