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.
