You can try a few things.

Pull it out, pull it apart, clean it and hit every solder joint with an soldering iron to resolder them in case of any dry joints. Some people supposedly have success with this, but I didn't when mine was doing the same.

Another is to replace it with a second hand unit. But from the amount of times I have heard this happening, it could only be a temporary solution.

Most expensive option, costs a few hundred dollars. Take it to an instrument specialist and have them rebuild it. It was the option I chose, so I came away with a brand new calibrated speedo.

I only pulled out my cluster, dropped it into them then picked it up a few days later all fixed up.

I assume you figured out how to get it all out?

I honestly can't remember, somewhere between $200 and $300 I think. but they essentially just replaced everything. So while it may be a few dollars, how untrustworthy mine was, it was still better then a speeding fine.

It could also be the drive gear in the TX case, or the sender in the TX case. The cog on the sender and in the TX case are either a fibre or nylon and if there has been any water in it then it may be damaged.
