CDM1250 Wont Turn On

[giles391rescue]

I have a UHF CDM1250. This thing worked fine when I plugged it in to turn it on, etc. Well, I finally decided to program it, so I read the original codeplug from the radio. The ONLY thing I changed was that I added new channels to it. No changes in radio configuration, etc. When I wrote the data back to the radio, the radio shut off. It took forever to get it to turn back on. I placed jumper wires on #7 and #9, only managing to get it to randomly turn on now. The fuse is good, it just turns on sometimes. You can press the button a million times and NOTHING, then all of a sudden you push it and it comes on. Any help will be greatly appreciated. OH, I did manage to turn it back on once and under "radio config" I changed the ignition sense to DISABLED. It was under "on/off & ignition".

I have had that happen a few times on those, I always save the codeplug before I change anything, normally if you dump the old code plug in it goes back to normal. Then start over and try again, that has always worked for me

That's the problem LOL. I can't get it to turn on now to write anything back to it. I do still have the original codeplug, but I can't get it to turn on except when it wants to.

Sounds like a bad flex.

Sounds like a bad flex.

agreed.

If you have a second radio, do some troubleshooting by swapping the control head flex cable.

It sounds bizarre, but that was the solution to my exact same problem some a few months ago. The radio I have never gets moved from its base mounting so idk how it could have gone bad.

Could it be your power supply or power cable?

I'm not sure. It was working fine until I wrote the new data to it. Then it was over from there.

hmmm thats weird that it was fine until you wrote to the unit. Mine was always a little touchy but it got worse when i opened up the head to clean the display and keypad. Now it only will turn on if the on/off / volume button is positioned at 2 o'clock and you gotta really push hard. Same thing to turn it off - it must be in the same position. The volume portion of the switch still works like new though.

Dunno if something went in your switch but just a thought. There is a contact plate right under the switch - maybe it's dirty? Still doesn't explain why it worked fine prior to reading/writing.

ooh Motorola...
