Helping out a friend who is not internet savy.

Lathe:
Ecoca PC-1860
built 1-31-2000
Shen-jey Ind Co

Has been basically trouble free until past 3 months.
Now has constant alarms
Servo off
Battery low
Cannot set coordinates
Servo alarm

Dealer/service has worked on unit , now says unit is dead.
Something about a board, if the board is taken out memory is lost forever?

Once during repairs it ran fine for one week, glitch free. As a test they swapped the board they installed at the beginning of the week, alarmed in 5 min. Put the "new" board back in, the new board alarmed in 5 min. Has not worked right since.

Question. Is there some service agency somewhere that knows these lathes?
