Couple of issues that I have researched the forum for answers and come away more confused then enlightened. Calling on the knowledge of Pinsiders for assistance.

1. All of the displays illuminated boards have the same segment out, lower left vertical. Where should I begin to look to diagnose, repair?
2. Shield kicker power kick varies from lazy to semi lazy. How the heck do you test a coils power? Took it apart, cleaned the sleeve and pole, no difference.
3. Voice quit working after adjusting pan volume control. Cleaned pan, adjusted balance over to the voice side, turned volume all the way up, now I have both sounds and voice but low. Every post I read ends with replacing IC3 Rom chip, is this where I should start? I have a multi meter and limited electrical knowledge working on automobiles.
4. Top of the playfield red bonus lamps (10,000-30,000-50,000), when do you score these points? Is it when you hit the target above these lamps?

Thank you Travish for the replies and advice I will give it a try.
2. A lazy kick return loops across and hits the top of the right kicker, strong kick will hit the lowest POWER target.
4. Great, no need to fix or aim for it then.

Thank you for clearing up points lights!

Checked the coil, it is the correct one. Was noticing all of the kickers are weak. For example, the top playfield kicker only shoots the ball out as far as the "i" in fire. As I remember playing the game back in the day that top kicker would shoot the ball clear across to the other side and bounce back to the "r" or "e". Is it possible I have a power problem, coil or other?

Thank's for the support Oilspot, I will update what I find as well.
Machine lived in a barn for the past 10 years. Was in fairly good condition when i got it except for a badly worn play field, flaking back glass and common electrical problems these games regularly suffer from.

My outlane kicker doesn't have a rubber tip! Going to Pinfest this weekend, looks like we will add this to the shopping list.
