TS-940 - SUBSCRIBERS'S INQUIRY REGARDING DIGITAL DISPLAY
DISAPPEARANCE
I have a Kenwood TS-940S. It has been operating perfectly
until just lately.
When you push the Power Button in, the digital display shows
but immediately disappears. While it is in this mode, the
automatic antenna tuner does not function and, of course,
there are no signals coming in, but the voice synthesizer
reads the frequencies. The last time I tried it with the
power button pushed in all the time was 2-1/2 hours before
any signals came through from the antenna. Then it seems by
releasing the power switch and then pushing it right back in
again is the only way signals will come through.
Could you give me some idea what component would be at fault
or what is wrong or where to look for the trouble? I do have
a Service Manual. I have been a subscriber to the Kenwood
Newsletter for several years. (ED Note: We have seen this
problem many times. Unfortunately we have no permanent fix.
However, the problem seems to go away if you unplug all the
connectors on the PLL and Logic Board to reseat them.
Perhaps one of our subscribers has found a permanent fix for
this problem??) (Thanks, John Holmes, VE5YC, P.O. Box 6,
