[CA11] M92650-S scanner issue
we have a older C-series MFD with a M92650-S radar scanner. it started having this issue and was hoping it might be repairable as we cant afford a new scanner

the scanner is spinning fine but when first turned on the screen it seems almost like it has trouble deciding the position of the scanner untill a few rotations later. also it doesn't actually detect anything as it spins. there is a fine line of adjsuting the gain that it goes from showing nothing to showing white out. the video shows what its doing on screen.

i was thinknig the position sensor might be an issue but when i pull it out, the scanner will only rotate for awhile before shutting down. with the sensor still it it will keep rotating so i believe the sensor itself is OK

in the MFD in diagnostics, it does shows it failed a few tests including 12v test. i used a multimeter on the scanners 12v and it shows 12v is fine going to the scanner

i have not dug too far else into the scanner hoping someone here might be able to help

RE: [CA11] M92650-S scanner issue
Welcome to the Raymarine Forum Kingfish999,

Based upon the symptoms reported, the radar indeed appears to have suffered a failure of its circuitry. Unfortunately, Raymarine's Product Repair Center can no longer services these radomes and open array pedestals which had been designed for use with C-Series Classic MFDs and hsb/hsb2/SL Pathfinder Series Radar Displays. While Raymarine's Product Repair Center can no longer service these legacy radar transducers, there is a fair chance that SeaWire Marine, Inc. (305.489.1600), a Raymarine dealer/installer, may be able to repair the MFD. It is accordingly recommended that they be contacted regarding the repair of your radome.
