I use and have 2 A21P's, great machines so well made.

Theres a known fault on some that develops over time. its the memory 
connectors that need reflowing.
this leaves everything running , but it  doesnt work!.
It can be done in situ ,ie no need to dismantle it , by a skilled techie 
by accessing the connectors via the memory cover.He runs the tip of the 
weller along the connectors . Thats enough to reflow the solder..
 with a 10x lupe you can sometimes see the hair line cracks in the 
solder connections.
