1720C went dark

[Anonymous]

Finally shook out some annoying problems with my M260 transducer and thought all was well.
Yesterday running out and both displays (1834C & 1720C) are operating fine. All of a sudden the smaller screen goes black. I can put GPS/FF/Radar on the big screen, so all sensors seems to operate, but the 1720 seems dead as a doornail. (First time this has happened in 8 seasons)

Trying to power on I get nothing - no beeps, no error message, nothing.

All electronics are controlled by same circuit breaker, that seems fine. I took quick look at back of display and saw nothing obvious.

Any thoughts?


Thanks.

Ensure you power system is fully charged. Remove all cables except for the power cable and remove any card you have in the map slot. Then see if the unit will turn on. If not then you either have a blown inline fuse in the power cable, bad power cable, or something bad inside the display. If the unit does power up; add each thing back one at a time to find out what is taking down the display unit.
