My stern flight 2000 act funny with the display, when the machine is an attract, the display altern between the high scored and the last scored. With the high scored, the display look pretty good, but with the last scored, some digit are not always there. When i play a game,some digit are on and off.
i already change the power supply board and the connector to the power supply, and there is a new SDB (rottendog). If it's connector causing this, can someone tell me wich one i have to redone? Is it possible that i have and MPU problem?
thank,s Gino

Je crois qu'il doit y avoir des pins de display dont la soudure est craqués, c'est très commun. La plupart du temps on fait juste les faire fondre mais idéalement il faudrait enlever la soudure et les refaire.

I doubt it... I gave him tested displays. And if some solder was cracked the problem would always happen. Not just with the last score playd.
Gino, does the problem happen in the self-test mode?

No! i just check and the display are fine in test mode. It's start to dim when it goes in attrack mode. When I turn the machine on, she search for ball in the playfield, during this the diplay are fine, when all the ball are in the lane and she goes in attrack mode everything flicker.
any idea

My guess is the U11 chip on the MPU. Try reseating the U11. If that doesn't work, swap U10 and U11. If that doesn't work, try reseating U20 and/or swapping that with another U20 if you have one. If that doesn't work, try wiggling various wires at J1 on the MPU while the machine is in attract mode. You can find out exactly which wires to wiggle if you know what segments or digits are always off. I don't think the wires are the issue though, since as Sparky pointed out, this would cause the digits to be missing for all scores, not just last score played.
Could it possibly be a 5101 problem ??
Of course, if you have another MPU that you can swap in, that would at least narrow down the problem. Doesn't sound like its power or SDB related.
Measure the high voltage output (TP2) on the Solenoid Driver. It should be between +175 and +200 volts DC.
The other thing to check are cold solder joints at the header pins of the displays. But, as Sparky commented, the display would be showing missing digits or segments intermittently, but now always related to a specific game mode.

I do some test and this is what I found. When I put only 4 display (3 players display and 1 credit display) everything is fine, the probleme start when I put the 4 display. I try to isolated if one display cause the problem, but as soon as i remove one of the four, the probleme goes away.
I try to move the display around to see if it's located at the same place but no. If I remove the second display... everything fine, the thir5d one everything Ok. As soon as I put the 4 display... probleme?
Any Idea!
Can I change the MPU with the one in my seawitch and leave the rom there. Is it necessery to change the rom, if I just want to test the display?

Just for specification, the digit are not really on and off, but alternate between bright and dim.

Sounds like the MPU can't handle the signal to all the displays at the same time...
Or the solenoid driver`s high voltage current capability/regulation is not able to handle all five displays...

The SDB is a new repro i have put today, got the same problem with the old one and the repro.

Yes, you can swap the MPUs. Same configuration. Sounds like the MPU can't handle the signal to all the displays at the same time...
Can I swap with my Dolly Parton MPU?
