I just bought a steel bout where a Koden MD-300 radar was installed. The screen seems to work ok and the antenna rotates as it should. But there are no signal shown inside the circle.
Has anyone knowlegde of this symptom?

 

Is it one of these? I have a full repair manual for this model, as I own one.

 

It looks very simulare... exept mine is named MD-300. But maybe I can use the same manual as the antenna should be equal!?
Can you provide me with Service Manual, or is the file to big for e-mail?

 

If you private message me your Email address I can send you it by email in 2 parts.

 

This is the Antenna unit.

 

Then it is working again
It was bad connection in the plug that goes into the Antenna modul. I pulled out the wires and soldered them directly on to the pins....

 

Hello, I have a Koden MD-3000 with the same problem, I have tested the antenna with another radar and it is fine, the problem I think is the radar. Do you have any idea what it can be?

 

This will give you a start pichote65. The manual has 109 pages & the Logic part has 40 pages. Will post the fault finding chart, hopefully its the same as yours.

 

This is my display unit.

Thank you very much, I will check with this that you have sent me to have if I can find the fault. I'll tell you.
