I've got 251,000 on it now & it doesn't use a drop of oil, has been trouble free except for this problem & a few other electronics problems ( memory buttons, remote doors, etc. ) I do pretty well without dash lights, but it would be nice to have them again. Any help would be appreciated. Thanks

1993-1994 have issues with the cluster lighting going out due to failed/bad capacitors. I would check them on yours

If you replace those, you should be in good shape. You shouldn't need to replace the board unless it's damaged

See this thread:

It's an archived version of this one:

The post right after the one I linked has a picture with the board

EDIT: Replying to a bump on a dead post... Good for information anyway

You have a different issue. 1993-1994 LS 400 have different clusters than 1990-1992.

Suggest to continue this in your thread as it's not relevant to this one - https://www.clublexus.com/forums/ls-...-at-night.html
