Intermittency issues are not unusual with these radios and radios of
this age. Time for a connector cleaning to restore life for another 10
to 20 years. Please just clean the connectors and DO NOT spray
anything into the radio.

Thank you all for the quick answers!
This evening when back home, I was ready to open covers and take a
look inside the Orion, but before doing that, I switched it on and,
with my surprise, the noise heard from the speaker was different. So,
after having set the correct display contrast, I tried to listen to
the 20m band it was busy! Then, I tried change the band, mode,
transmission... the Orion seems fully alive again! Nothing has been
changed from yesterday, but today it works. Since I don't believe in
miracles, I wonder what went on? I'll check it in every function, but
it seems fine.

Enzo,
My Orion-II had exactly the same symptoms, on a couple of occasions.
The master resets helped for a while, then the same problem came
back. Looking at the DC power cable connector, it was fine. So, I
opened it up.
The first thing I did was to replace ALL the electrolytic capacitors
on the A9 power supply board with high-quality 105C capacitors. I
then checked both batteries (CPU & AT), and replaced them. The last
thing I did was to DeOxit ALL connectors in the radio (quite a job).
It has never had a problem since.

Hallo everyone,
I'm a happy owner of a Orion since 2005. Today, while it was
transmitting my home energy was suddenly interrupted. After
switching the RTX on, it started behaving in a strange way: both
VFO seems ok but no band reception; only the buttons around the
display are active, the others don't work; no transmission. I
performed a Master Reset and then a Ram Clear (followed by a master
reset). Now it switch on, the volume goes up an down, some noise
comes out from the speaker, but the 20m are silent, only electronic
noise.
Is there any clue to bring it alive again?
Thanks and 73 de IK3SWB, Enzo.
