    Sounds like some of your digital display has crapped out. I think your best bet would be to look for a replacement instrument cluster. If nothing was working I'd suspect it was a power supply problem, but since some of the cluster is operating it seems like that isn't it. The cluster isn't all that hard to replace I've been told. Here is a thread with pics of a 1987 Lincoln Continental cluster so you can see how it's put together. Not sure what model lincoln you have, but if not a Continental it still should be similar. Folks on that site might be able to better assist you also. They may have a better handle on this particular issue.

    Since the display is flashing occasionally, I would assume a loose connection. That big 18 pin connector in the upper left of the middle photo from the Lincoln forum would be the first place to look. Most everything else is well attached to a pcb and will be unlikely to flicker.

    This is an Electronics site and not an Electrician site no?

    It is a circuits site. Pretty clear in the URL, no?

    Well seeing how there are "circuits" in the Electrician trade. You may see as how I made a mistake. Electronics are about gay as it gets anyways. Screw this site. I'm deleting my profile

    I am not sure if I should be thanked, banned or be put into protective custody.

    I have seen this in other clusters. Remove cluster, carefully remove shield, then pcb. You should see "tabs" that drive meters and gauges which are making bad contact, along with checking for cracked solder joints where the cluster connector meets the pcb. Hope this helps.
