NX-5800 won't turn on.

[sraider]

Have power to radio and ignition sense wire. Worked fine one day then the next day won't turn on. Tried holding power button for 5 seconds nothing. Is there an issue with these radios or just bad luck. For what they cost new, can they be fixed?

This is actually the second one that stopped working. The first one that stopped working this spring hardly gets used, the one that went now gets used alot during harvest season but then sits mostly unpowered for 10 months.

Also does kenwood make a simpler nexedge radio? They are only used for our own company. Don't need a 1000 channels when I only use 3. Have our own repeater system so don't need trunking. And the programming is a hard learning curve when you rarely use the software. I do have some nx-3820, but they are also way more than I need.

Nx1700NUK will do the job.

As for the 5800, checked grounds? Fuses? Etc.?

yeh everything checked out, replaced with a nx3820 and powered up fine. But needed to replace mounting bracket. Why can't they have all the same mounting bracket, ( I know I'm complaining now)

May want to consider shock-mounting the radio if it's in farming machinery.

by the sounds of it it sounds like the power management ic died. i have seen a lot of them go in the last few years. did you happen to jump start that vehicle? if it is the ic then yes it is repairable. and i agree if all you are using is just simple repeaters than a 5k radio and 3k radio are both overkill a 1k radio or before that a 20 series radio would have don the job just fine and they have GPS option too if you use that.the other bug difference is the Bluetooth the 1k radios don't have that option if you use that.

Do you know a place to send them in to get checked out?

We do use use bluetooth on one radio.

Looked at the software online for the 1800 and it looks like the old nx800. We have some them also.

 

[tlemke940]

so ya on that one radio or what ever ones you might use Bluetooth on use a 3k radio and save a few bucks and do 1800 for the rest and ya the 1800s basically replaced the nx-800 radios same brackets and hardware too except for the accessory connector

Vibration shouldn't be an issue, heck we even run a ipad for data collection.

My vote is for IC2, the power management IC, too then. I've seen two or three of them in buses/trucks in the last couple of years, likely after some kind of supply issue (e.g., jumping a battery that went open). There's reasonable filtering, but must be some kind of spike that happens at just the right frequency to evade it and spike the chip. Find the Kenwood rep here and they can refer you to a shop with the stuff to replace it. Should be someone in MSP.

I don't believe they would of ever been jump started, but I know battery chargers have been hooked up to the vehicles.

Just wanted to clarify – by checking "fuses", we meant the four internal fuses in the radio, F1, F2, F3, and F900. If you're lucky, it's just one (or more) of those, which is easy to find/fix.

Unless I missed it earlier, I believe United Radio is the name of a repair Depot that Kenwood has had us send some NX's to for repair.
