radio freezes

Okay so we bought several Kenwood tk280 ver 2 radios and a couple seem to have a weird problem, after a day of use they display 99999999999999 and won't do anything else. i have tried wiping and reloading with a program that works fine in all the other radios just these two are doing that. Any ideas? Could it be a firmware issue?

It could be firmware but it could also be a cpu problem. besides the display  dose it still work TX/RX with that displayed?

No once that pops up in the display it doesn't receive or transmit or show any changes in channels when the knob is turned.

My two Cents are try updating the firmware even if it is an in place upgrade. then if that dose not fix it read another radio that is working and dump that file into the radio and see if that works if it still don't work then it might be a CPU problem and it not economical to repair and that unit may need to be relegated to parts due to its age those are a 20 year old platform that is now been replaced 3 or 4 times over
