KX3 Power on issue

lockery
All,

I just joined the list and have a factory assembled KX3 for about the last 8 months.  KX3 has had little use as I worked on putting together the power supply and antenna.  I have discovered a new issue and I am not sure what caused it.

I updated the firmware to the latest version last week of the release firmware.

I believe I turned it on after the firmware change, but not sure now.

I updated the heatsink to the one from ProAudioEng.

I added internal batteries 2500mAH to make use of the internal battery charger and RTC.

Symptoms on power up:

TX light stays solid red.  triangle f (delta f) is solid orange.  OFS and B square (square around B) are solid green.  The KX3 would not power off, so I removed one of the internal batteries which allowed the unit to power down.

Thought issue was releated to internal batteries not being powered from a higher current source, so I put battery in and added external power.  Same as before and had to remove battery to power off.

Went to just external power, issue remained but I was able to power off.  Sometimes the KX3 power ups if I hold the buttons to turn it long enough.

Only change I did on the firmware beyond updating it was to have a startup message with my call.

I would appreciate any thoughts on where to start trying to figure out the issue.

Thanks,
Stan Frady, N1BBS

Few ideas
Unplug everything on left side of radio, but pwr.  Try again
If still a problem, Check /re-seat the flex cable between the two main boards.  Might have been pinched or moved when you added batteries.
