Update - it started working!  Not sure what fixed it though, might have been the order I made the connections in, or maybe some corrosion rubbed off finally.  Thanks again for all your help!


Great news!...always good to hear of an old warhorse living to
fight another day. Just be careful not to absent mindedly attach
a wrong adaptor and you will get many years of pleasure.
all the best

Thanks for the tips -
The adapter I have is really a step-down transformer - it takes 120V AC and reduces it to ~9V AC.  It does not have a "sleeve/tip" type connection - instead there is a wire terminating in two prongs labeled positive and negative, and a wire protrudes from the board with a socket connector for the prongs.  My multimeter confirms - it is AC current coming out. 

The user manual from Alain's site calls it a transformer, and it says Fidelity on it so I'm thinking it's original.  Seems odd though - modern computers all use DC current internally, and you all suggest your chess boards use DC.   

I guess that leaves me poking around inside some more and looking for broken connections.  Thanks again!

Hi Timster, I agree that you should invest in a multimeter, if you
don't already have one. If you put a multimeter on an original
Fidelity adaptor, you will be surprised to see it read about 12
volts! I have raised this issue before, but others tell me not to
panic, it is normal.
  What I did was bought a regulated adaptor, with a reversible
tip, so that I can use it on my Novag and Radio Shack machines
which take a 9volt negative tip. With a regulated adaptor, when
it is set on 9volts, it will read 9volts + or - 0.1 volt.
  The Fidelity machines, however, all take a 9volt DC positive tip
adaptor. You did'nt mention your adaptor, but
check the polarity to make sure the tip is set to
positive. In any case, when you turn on any chess computer with an adaptor and nothing happens, disconnect it immediately
and check the adaptor settings. The EAG is an expensive
machine, and of course the company does not exist anymore,
so if you cook it you suddenly have a very pretty manual chess
set.
  I don't have an EAG but I do have a Fidelity Elegance. When
I turn it on with no pieces I get lights prompting me to put
pieces on the board.

Hello Timster,
I don't have a EAG, but my Elite A/S needs all pieces to play.
However, when one piece required is forget, there is some leds that alert you.
Do you use the correct adapter ?
Perhaps the problem is after the 9V (uP needs only 5 volts): you need a multimeter.
Cordialy.

This is probably an easy question for anyone that has one of these:

I have an Elite Avant Garde (Model EAG) that doesn't turn on.  I don't have any pieces for it - are pieces required to get it to turn on?  There is 9v at the circuit board pins where the power cord connects, so there is definitely juice getting to the PCB. 

Thanks for the help!
-Tim
