Yesterday when heading out to catch some fish the combo unit on the boat
showed a problem. The display had several narrow vertical white lines
across it. Although the lines were not helpful they really did not
interfere with reading the display. As the day warmed a few lines went
away
but most remained after about six hours of ON time.

The unit is a 1999 Lowrance with a black and white display.

I fear it may be time for a replacement but would like to have your views.
I could send it back to Lowrance for the flat rate repair but am not sure
the unit is worth the cost at this point. Perhaps I'm really just looking
for an excuse to buy a new unit???


For me, the issue would likely hinge on how much of a PITA it would be to
change out the transducer for the sounder section of the head unit. That's
usually where the most difficult part of a new installation lies, mounting
the transducer and fishing the wires to the helm. Another issue is whether
your current head unit is flush mounted or on a gimbal bracket.

Assuming your current problem is not related to a faulty transducer, but
rather a faulty head unit, as seems likely, I would check and see if a new
model head unit could be purchased that would be compatible with the
existing transducer and connector (and helm cutout if flush mounted). If
so, that's probably the direction I would take. If not, I'd have to weigh
the benefits of a whole new unit and the pain of installing a new transducer
versus just getting the old head unit fixed and not having to deal with a
new transducer installation.
