The early microprocessor had some bugs in it that would cause problems like
this. If it's marked XX15053-470 you should replace it, stock number
233180. New & improved version is marked XX15053-47A.

| I have seen some of these that unless you go to the last parameter code
before hitting power , it will not store input values you have set.

| Thanks for replying.
| I have 2 set of 185AA with me with 2 new eproms. 5v

| exit the service mode, the new value already gone.(in
| this case the vertical size is wrong).
| So there must be a trick or something....to store
| these data to the new Eprom
| Thank you
