Same here. Kyocera was very good at providing replacements and
covering reasonable labor. <br>

The KC 120 had some issues with soldered connections on the
module looks like a cigarette burn from the back or maybe just
a blister, it will be on the shrt side of the module. Anyway
it will drop the module in half most of the time or try to
work while it burns the poorly soldered connection, it will
also get bery hot as it is arcing inside. You need the SN# and
call the manufacture if its on there list it might be
replaceble they can tell you. As I recall its a C that is the
SN that has an issue but check to make sure.<br>

I have replaced entire arrays because of this. <br>
