Default Moto CDM1250 No Lights

I have a CDM1250 that has no back light, TX/RX, Monitor, or scan light. I have checked the ribbon cable the head was placed on another CDM1250 and it worked. I checked the CPS to make sure the lights where turned on but nothing. Any ideas?

Default cdm1250

cdm series radios are known to have this issue. especially if the control head is remote mounted. you could try replacing the cables with new but quite honestly im willing to bet the electronics are shot in the control head. your best bet is to replace it.

I put the control head to a different radio and it worked fine. It is not a remote mount so I am hoping that its not in the radio itself

Default This might be the probelm

Batboard • View topic - Backlight not working on CDM1250

if you think about it that would be it. I tired putting on a different head and that did the same thing. so that must be it

Does anyone have a picture of the R0410 P/N 066257B47 fuse on the PCB board? I can't seem to find it to save my life.

If you have the manual in PDF format, use the search function of Adobe Reader.

That did the trick. Removed that fuse and put a piece of solder there and works like a charm. Thanks everyone.

Uh, just want to point out the obvious fact that something caused the fuse to blow in the first place. Did you find the cause? Replacing the fuse with the solder may put your radio at risk of a more serious failure if the same fault happens again.

Yes looked at everything. It happened when we were changing the unit from remote mount to dash mount and forgot to turn the.power to the unit off.

That would have been my second guess. Glad to hear it's working for you.
I really like the CDM's I have, nice radios.
