Old school Koden radar MD 3404 - issues

[blucassen]

Hi all,

I have this wonderful 20+ year old Koden radar on my boat but I'm now unable to get it to start again.
The power cable going into the back of the monitor shows system voltage, but the monitor just doesnt respond, there is absolutely no sign of life on the monitor when pressing the power button (or any other for that matter). There is nothing that I can think of that would have happened to the monitor to kill it.
Couple of questions to anyone familiar with these old Koden radars
- Should the monitor come on if there is positive voltage going in
- The mast has been removed since last use, and the ridiculous mess of connections appears to be correctly connected (second photo). However, if the magnetron is not properly connected to the monitor could this be the cause for failure to start up
Any other recommendations or things that I might be missing (I'm far from a techie)

Thanks in advance,
Barry

You should see some signs of life when you power it on no matter how it's connected. It may be hard to believe given the age of your radar but electronics do have a lifespan.

Take the display to an electronics technician. It doesn't have to be a marine electronics tech. Let them look it over, they can tell you if it's truly dead or if it can be repaired.

Or modernize. You could easily drop 40-100 pounds with a new radar while reducing your power requirements.

Thanks for the response! I've tried a few more things and decided to just kill the radar, I was considering replacing it as part of a wider navigation electronics update so just decided to go for that
