Joe1958,
Is (or has) the FCV-295 ever been connected to a computer? A blown NMEA chip will short the +5V to ground and kill the 295's receiver. One way to confirm this is too select a range of 1000ft and set the gain manually at 10. If you don't see any background speckle I would strongly suspect a blown NMEA IC. If you are connecting the FCV-295 to a computer you should use an Opto-isolator to protect the sounders NMEA IC. Unfortunately at this point you will need to send the sounder into our service center.

Joe1958,
That's good to know that the receiver is still alive. The other test is at the dock with the TVG Level and Distance down and the gain at 10. If you see a very weak bottom then I would suspect the sounders power supply has an issue. Either way you will need to send it to a dealer or into our service center.

Joe,1958,
The default TVG's are 4 and 600ft. So at the dock set the TVG's as low as you can with the range at 30ft.

Hello Snips,
Hope you and all staff have a great holiday season times, as a mention 1rst post, when bought the trawler with unit installed, and previous owner told me the unit was replace 1 circuit board inside, for some reason I just done couple night in ocean and unit happened same trouble in the past did not show the depth number where worked on ocean, send unit to workshop in my area, but seam they were too busy and just small job for them " I reckon", within a month they haven't got time to look at or touch unit, so I grab unit back home then opened up checking all circuit board, it noted a circuit had liquid in 1 area looks like coffee or similar, it's sticky and thick on top and some screws didn't screw down properly, I used circuit board cleaner then put it back and tried, but nothing happen, I think circuit been damaged, so question: I can order circuit board or not? Here is the circuit board took out from unit.

Merry Christmas and happy New year.
Best regards
Joe

You should be able to order whatever you wish from your authorized Furuno dealer. Furuno doesn't sell direct to customers, so any pricing availability should be done with your dealer. The FCV295 is current product so getting parts shouldn't be any problem.
