You have to go into the test for each one and run through the test to clear the dot.

Sometimes things like this come up if you have the glass off and are doing things to the game..

For example i took a ball out of the shooter lane without launching it and proceeded to use that ball to test targets and i got a credit dot saying the shooter coil was bad. It obviously wasn't but what was happening was unexpected.

Go into the individual tests for each one and make sure they open/close.

Go into switch edge test, trigger each of those switches. If they work they should clear the credit dot. If they don't work you have some fixing to do.

If they work and the error remains, consider a factory reset to clear them and see if they come back. You will lose scores and any adjustments you altered from factory settings.

For #1 do you ever pick super jets with the claw? Sometimes when it hasn't been triggered in a lot of games it thinks the switch isn't working. Play a game and drop it in there, see if that error still comes up.

Claw super jets should be the switch over the pop bumpers that the ball falls through when dropped by the claw. Do a switch test and activate the switch yourself to make sure it registers, possible you never drop it down that hole while playing? If so that could also be the reason. As for the flipper optos do you just use the handles when you play and never the flipper buttons? That will give you the same problem. Other wise take a cue tip and clean the lower optos on the flipper boards located beside the buttons on the inside of the cab
