We did our best with the cap kit and adjustments but the play testing revealed a monitor flare. The kind that results from a short in one or more of the guns. It was time to roll out the rejuvenator. This device essentially pump too much voltage into the guns to try and burn off a short created by dust or other airborne particles that can collect in the (relative) vacuum of the picture tube.

It is not without risk. You can destroy your tube if you push too hard but it can bring a dying tube back to useful condition. If you are losing it anyway, it is worth a shot.

This time it did not pay off. We clear a short on the Blue gun, but the Green short remained. We just could not save this one. Fortunately a spare tube was available and we swapped it in on that newly recapped chassis. Frogger is bright and colorful again.
