Simrad XX44/54 Fault

Fault symptoms
We have seen a few cases where the picture on
XX44 units has become intermittently distorted
i.e. the display looks checkered with random
patterns and may even fade out and
turn white. The fault has mostly been observed
during warm-up when starting up a cold unit.


What is causing this distortion?
Insufficient electrical connection between the
display cable and the connector due to a
difference in tolerance of the flat cable and the
connector mounted on the mainboard.

Solution
There is a factory repair for this problem which
includes changes of components on the main board.

As all units are currently under warranty we request
them to be returned for remedial work.

It would be prudent if you contacted your customers
to arrange thisbefore the fault developed as replacement
with new units cannot be provided.

We will post further info when the components become
available. In the short term be familiar with fault description.
