Happy New Year QRPers in the Group!
Bought and assembled my Christmas present which was a QCX /40M that came
from Turkey with a chassis kit!
I assembled it over the holidays and was so disappointed in the outcome.
With power, dummy load, keyer paddle and earphone in place I turned on
my power supply (RS-7, 5 Amp, 13.8V) and got a
Big Bright LCD with nothing but white squares on it. I know R47 is in
play because it goes from the squres to a
blank screen when I try to adjust. The kit is a Rev 4 and the 28 pin/IC2
is Version F
I did everything mentioned in the QCX/Trouble, but nothing changed. I
even looked for shorts on IC1. After checking all the pins
including reflowing the pins/pads, it almost looks like the 28 pin is
dead, not responding or not communicating.
I am not a Electrical Engineer, but I do own and run
Kitbuilderssoldering.com with kit building
experience since joining NorCal in 1994. I will contiinue to look at
this problem and hope that I
have a break thru..................
