Hello Chock,
Thanks for asking. The problem we have is you can not see the screen most of the times, if we are lucky it can still be used manually. We have gotten over the years all kinds of codes.
The main board has been replace twice in the almost 5 years that we have had it. Yesterday it did a new one, the air went on without anyone using it.
It has a life of its own, as you are cutting the screen keeps resetting and much more....
