KX1 Dead U1?

Stuart Cartlidge
Hi folks,

I'm in the process of installing the KXB3080 adapter in my KX1. All went
well until page 11 of the installation, checking current drain and voltages.
I had a slightly high current drain (42 mA) and while thinking about this I
suspect I've absent-mindedly poked something with the power on and zapped
U1. Until then I had the revised 1.02 firmware installed and apparently
working OK with my previous parameters in place, now I've got no display or
sign of life from the firmware. Replacing the 1.02 firmware with the
previous 1.01 version returns life back to the KX1 with a normal display,
full tuning, band change, etc.

To me that says I've zapped U1 and just need to buy another or could there
be another cause I'm not aware of?

Thanks,

Stuart G0MJG
