Something that I should of taken care of earlier before I started my restore is this issue I am having. I got this taxi in as a train wreck. Got it working 100 percent and then started having a slight issue before I tore it down.
Game has pinscore LED displays so nothing is outgassing before I start.
When you first turn the game on only a few segments on the display come on. Maybe a couple more lfickering as well. Many inserts dim. CAB lights in the back lanes especially worse than the others. If you start a game immediately the coils are very week. Can't even shoot a ball in the outhole to the trough. After a few minutes coils are good and inserts are good and most of the display segments are back. After about 10 all the display segments are nice and bright.
When I started on the restore I did the cabinet first. When I cleaned all the boards I replaced C1, C3, C9 and C10 on the power supply board and the big blue capcitor on the lower right hand corner of the head. I plugged the old playfield back in outside of the cabinet for testing purposes and the issue is still there.
I'm guessing there is another capacitor I should be looking at replacing but I'm not sure which one. What seems odd to me is coils, displays and lighting are all different voltages. Wall voltage is fine.
Playfield is almost done being restored. Should be back in, in another day or two. I can still boot the game and check the displays without the playfield in though. Any other suggestions to look at?
