I had the same issue ..It's cold solder joints on the back of the instrument cluster. I took it out and touched most of the solder joints with a soldering iron. It worked fine afterwards OR replace the cluster.
What computer did you replace? Are any other items not working at the same time as the instrument cluster?
the computer i replaced was the one mounted on the left fender next to the battery.
Your problem might be like my 98's pull instrument cluster and redo solder joints at
main plug.My had a code of no TCM input.
