NX-5900 Reboot/Restart Fix?

[cruzinlow66]

Hello All!

Our shop has received an NX-5900 for service. Customer States the radio randomly reboots/restarts and when it does restart there is not a turn on beep like during normal power on. I have confirmed and witnessed the issue several times. I have narrowed it down, with this forums help, to the Auto Recording being turned on. With this option unchecked, the radio no longer reboots or restarts and all is well. There is no microSD card being used. Customer does use this feature for recording and playback. Have upgraded firmware from 5.01.00 to 5.13.00, but the issue persists. I never saw a fix for this issue in searching more of the forum. Has anyone found a resolution for this exact problem? More insight is welcomed!

Did you submit a tech support ticket through the lmr portal?
Do you have an frp form to fill out, if no, email me and I will send it.

You could try changing the record time on the internal storage also.

maybe, if possible just to test roll firmware BACK instead of forward to say 4.6 and see what it does

No tech support submitted yet, will ask higher ups in the office.

Record time choice was 30 or 60 seconds, both had same issue.

Haven't tried rolling back firmware yet, I can try it. Have seen posts with older firmware with similar reboot complaint.

that is interesting as I think I said back up the chain that I myself have not seen that and a large number of NX5xxx out in field

Sounds like an issue we had with NX-5300 portables. I think Kenwood claimed there was faulty onboard memory or something. They weren't specific. It went from FTH to Kenwood factory for repair. Don't expect transparency from Kenwood.

I have issues with the NX-5700/5800 doing reboots for up to 20 minutes. I am however using the 3 ref units with one control head option. sometimes happens when turning on and sometimes when switching from one rf unit to another, sometimes when turning on/off scan.

I have a Customer with a triple deck
(3 NX5700 decks) with dual KCH20R heads.
for about 2 years now.
Never a problem.

Sorry for no updates. Customer wanted radio back in service and was OK with record being turned off. Has been back in service for a couple of weeks without reboot issue. FYI, different older firmware versions did not make a difference, all still showed reboot issue. Thanks for the replies.
