Samo on older CNC machines in our mechanical shop. Some very large horizontal lathes (we make and repair rolling mill gear on them) are relatively old but work really well. They still have Fanuc and Sinumerik control modules with CRT on them. And yes burn in is there , and very strong. Last time when CRT died , repair Maister just replaced it with generic 12" industrial LCD.
