Hi there.

I have a furuno fr2105 x band radar.
We went on sea trial on sunday and it was working fine.
Today we get a "Signal Missing - Video" alarm with no radar echo picture.
Radar continues to rotate while alarm is present.
Gyro feed is correct.

Have tried:
Power cycling
Manual tune
Tune initialise
Remove ARP board
Check connections both ends at the unit and console.
Run the self test page with the following result:

Antenna Speed 23.6rpm
Trig Frew 912hz
Mag current 4.9v
R. Monitor 1.4v
Tune Ind. 2.7v


Any ideas greatly appreciated!!!
Thanks :)
 
samjeffs,

It sounds like it could be a Processor Board (SPU Board) problem. How many transmit (TX) hours does the Magnetron have on the system..?

Deep Blue - :think
 
samjeffs,

Those transmit hours are not excessive, so it might not be the magnetron. However it could be a processor board issue (SPU Board). I would recommend contacting an authorized furuno dealer to take a look at the system.

- Deep Blue
 
Replaced the SPU with a new one and changed all the settings and still no luck, video signal missing alarm still present. Cable checked fro continuity and is ok. :questions
