No Speed or Temperature with DST800

[flyboyscd]

I installed an I70 system on my boat about 1.5 years ago. The system has masthead wind, and DST800 for depth, speed, temp, and also an ITC-5 unit. During the last couple of months the speed has been intermittent, and I'm getting no reading on the temperature. Now, the speed has completely failed, and when I search for transducers in the setup, it does not see speed. Also, the LED for the wind on the ITC-5 is blinking on and off about every 2 seconds.

I'm assuming the DST800 has failed, and was wondering if there is anyway to confirm this. Also, I'm located in Trinidad, and was wondering if there is any way to get warranty support down here. The system was purchased from Defender, and is less than 2 years since it was purchased.

Thanks for the help.
