Have you repinned the connector? Flickering is pretty indicative of a burned/bad molex connector.

Those lamps are special because they don't blink with the relay. DE is using half of the 12vac to power those lamps. That means they are have a 60hz flicker to them when LEDs are used so they do the strobe effect horribly.

I did something crazy in my game because it bothered me. Half wave bridge to make DC volts. Electro cap to smooth. regulator to chop the 12v down to 5v-6v. Then I had a nice smooth DC voltage to power those lamps with no AC cycling flicker to it.

You could run a new wires down around the relay to power those lamps with the normal 6.3vac

you could move those lamps to run on the normal GI that blinks with the rest of the GI.

It is like eight or so LED lamps so the extra load is minimal. Should be OK.

Be careful in games with trough optos. If I remember right Baywatch has a similar GI string by the flippers so they don't blink with the relay. The gotcha is the ground return wire also goes to the trough opto ground return. If you move those wires to the normal GI I don't think that opto circuit would like AC volts on what is normally the return wire.

In that game I have a switching PS doing the GI. I ran an extra wire run before the relay (so no blink by flippers) to the PF lamps on this circuit and now the SMPS also lights up the trough opto. I get a bit anal about the GI strobe light effect. Smooth DC volts look so much nicer. EnerGI is probably doing something similar, but I am not really familiar with that product.

Another trick which i don't know if it will bother your EnerGI is the put a power resistor across the relay. Low ohms, like less then 50, 10W resistor. That way when the relay turns off, the resistor still lets a trickle of power to the lamps making the blink of the GI not so hard on the eyes when LEDs are used.

I will notice it right away. I think the strobe effect from 60hz and even 120hz bothers some people more than others. I remember back in CRT monitor days I would walk by someone's PC and notice they have the monitor on 65hz. I would bump up the frequency or show them how to do it. A lot of people did not even notice a difference but bothered me.

If you set your phone to record slow motion video you will see how the AC GI lamps are blinking rapidly.

Any advice would be appreciated——slid the playing field glass off to reset a DEAD target that got knocked out of place (didn’t touch anything else). After turning the game on, it says one ball missing and launches a new ball, and after the new game loads the tag button doesn’t do anything. However pressing the flippers a few times makes the ball launch. Finally, it doesn’t recognize the ball exiting the play field.

okgrak I'd like to do the same on mine to reduce the flickering on the lower GI. How exactly did you do it? I see that lower GI (purple-black black) is on a different string but where along the wiring did you reconnect it to use the other GI string? I assume not rewiring the connection to each individual bulb socket, but it sounds like also not up by the connector?
