HI,
Here for sale is a Smart AV Tango, the screen although working seems to be unresponsive at times on the right hand side, ( touchscreen ) and 2 or 3 of the motorised fadars seem to fight back when being moved.
It was mentioned this could be an earth issue but im unable to check.
I bought a new power supply for it some time ago from Japan for £160 and is of medical grade.
I also have its software.
This unit weighs alot so will be collection only ideally.
Thanks for looking.
