There is a (3 minute?) warmup time.. sometmes for some reason the contrast gets adjusted.. have you tried to "increase" the contrast during the warmup time? You should see the countdown timer for warm up...

North-easter and anyone else with JRC Radar 1000 problems

I am having the same problem on a unit I salvaged from an abandoned boat. I contacted JRC who told me the main board needs replacing. If you repaired it what action was needed?

Re: JRC 1000 Radar won't power on??

I have got one.
When first powered up, it takes about 90 seconds before the display will show the sweep.
There is a count-down in the centre of the screen.
I cannot remember if it beeps when I first power up. I suspect it does.

Check the power supply. Make sure you are feeding enough volts. Start your engine to improve the voltage supply, if necessary.

Re: JRC 1000 Radar won't power on??

Keep in mind..
A voltmeter is not always the best tool, troubleshooting 12v systems..
They are sometimes too sensitive for the task..
I have been fooled more than once, by a digital voltmeter..
It will sometimes read 12-13 volt, but there will not be enough amp's to light a 5W light bulb at the socket...
Most Car electricians, uses the oldschool circuit tester with a built in bulb..
For circuit testing i mean..
It is a little different, when testing circuitboards..

I always have one of these lying around... : PICO WIRING 0690PT - Pico Circuit Testers - Overview - SummitRacing.com

Just my thoughts tho...

My JRC radar did that . I was quoted $650 for repair. Bought a new radar. Definitely not from the people who gave me the quote ( Victoria Marine electric)
