New humminbird 1199ci hd si unit will not turn on is there a soft start ?I have got 12.4 power

With this type of issue.. its the transducer mounting ...99% of the time!!

May require a software update.
register your unit at OnixSeries (this is a link to humminbird)
On your "My humminbird" page you will find free software updates for your particular unit.
download the latest update to an SD card and follow the instructions for the installation process.

Make sure all your wire and contacts are pressed in good, try taking your finder off the mount hold in your hand while going fast, see if it still goes off, if it does you might have a bad fish finder, or transducer is hitting hull or loose wire some where.

Do a master reset on the unit. restart and cross your fingers. If this does not resolve the problem you probably have an internal fault with the GPS unit.

The Power Supply just crapped out, Sorry.....

If you have put power to the gps antenna then there is going to be a problem with your gps antenna. The Humminbird gps antenna gets it power from the unit. If you have done this you will need to contact our customer service group to get it resolved. There number is 800-633-1468.

The first thing you need to check is if you have sufficient power going to the fishfinder. Take a multimeter and measure the dc voltage going to the display when the unit is off and also on. If this is below 12 vdc this is your problem. You will need to check for loose connections and possibly replace your battery.

If the voltage is good then the problem lies within the display. Unfortunately, you would have to contact Humminbird directly to return the display for repair or purchase a new fishfinder.

Hi!
I suspect that the software is corrupt in your unit.
