One thing you could check is whether the metal shield cover on the 2M
module was installed in the correct position. I had reduced output
on 2m (0.3w vs 3.0w) when I re-installed my module after receiving it
back from Elecraft (after getting some mods and repairs to my field
tester unit).
I mistakenly installed the cover backwards so the edge of the cover
came into contact with the TO-220 RF output transistor
leads. Reversing the cover so the cutout notch was in position over
the transistor leads "fixed" my low output. If the module cover
makes a hard short across transistor leads, that could result in the
dimming display and other issues you are seeing? The cutout in the
lip of the cover is very small so one could overlook it.

KX3 2 meter module transmit problems, not sure what to try next?
When I key mic in 2 meters, display dims and KX3 beeps twice, no
output, red led lights. When I push xmit button KX3 locks up, only
way to recover is turn off power supply?
Receive works great, no problems at all.
HF works fine, full output on transmit.
I switched out everything from SMA antenna connector, different
cables, 3 different 2 meter antennas. Only cables connected to KX3,
mic, power supply, and antenna.
Tried different power supply. I have had trouble with the internal 2
meter antenna, mini coax cables, but checked them, they look ok and
connected. This just happened when I tried to use it for VHF contest
yesterday, 2 meter transmit was ok before this.
Any help would be appreciated. 73 Thanks
