I now have two FED Etude stereo projectors (gray and orange), however in both, the left lamp is not working. I just cannot find the problem despite taking them apart to the last screw, bulbs are fine. Since both projectors suffer from exactly the same issue maybe I am doing something wrong? There are only 2 buttons for the lamps, but the left does absolutely nothing.
One projector will be converted to use modern CDM Lamps but I'd also like to have a working original one.
