repairing Fish finder

[Baskett-o-fish]

On the boat I just picked up there is a fish finder mounted on the dash. I tried to get it working but no luck. I traced all the wires and everything seems connected. I hit power and I hear it beep but then no screen comes up. Does anyone know where I can get this repaired.

You might want to contact the manufaturer via the internet. They'll get you going in the right direction.

You might want to check the in-line fuse if it has one. I understand everything is hooked up but it sounds like the fishfinder starts to power on, then dies. Normally (this has happened to me several times) there is a high resistance connection somewhere in the circuit. 9 times out of 10 I have found that it is the in-line fuse holder, salt water gets in and corrodes the connectors. Try to bypass it (just for testing purposes) or replace it, if this does not work then check all connections and if they are corroded then clean or replace, another good source of trouble is if there is a butt-splice in the circuit, they will also let the water in and corrode the wire. Hope this helps and good luck.

might check on , contrast and brightness settings ? , viewable angle check . back lighting setup ? . Some units standing on poweron switch for 20 secs when power it on, puts them in factory default and demo mode ? might try it .
