My 3.5 year old Simrad CX44 Navstation packed up last weekend whilst I was using it, leaving me with only a few days to get it sorted if we were to have radar on our holiday. Explored various replacement options, but as the CX44 is discontinued and the replacement NX-45 doesn't support the open scanner I have - figured I'd give Simrad a call.
Within 20seconds, I got a very knowledgeable guy and when I explained I was happy to wield a soldering iron, meter and oscilloscope, he suggested a few components which could give rise to the symptoms I was seeing.
Well, he was right on the money with his first suggestion. One of the schottky diodes in the switch-mode power-supply had failed (gone short). 31p later, my plotter/radar is working again /forums/images/graemlins/smile.gif
Great service by Simrad - its very unusual to get put through to someone in the UK who can give component level info these days!
