I replaced a burned out resistor in the monitor circuit board.  We wanted
to figure out why it was being burned out but we could not locate a
replacement for the TIP29 transistor that we suspected was bad/the cause
pulling down the resistor.  Makes sense to replace the entire monitor, but
it'll be green not blue text.  Next workshop someone may want to bring a
TIP29 or equiv. to continue with the repairs.
