[LW] [LW11] Radar repair

[Philtadd]

My radar (4kw 18” digital radome, E92129 0540307, network SeatalkHS, software 1.04.) appears to be dead. It displays a snowy screen from about 80% gain otherwise nothing. I have spoken with technicians from Lusty and Blundell in New Zealand who tell me the magnetron has probably failed. This cannot be replaced as there are none available in US, Australia or U.K.

I was told that the hours run can be found in diagnostics, wrong. Is there anything I can test, thermal cutout, fuse, sticking motor? Should I ignore it for the moment and replace with a different make when other parts of the system go wrong?
