1999 instrument cluster

My 1999 1.3LE has a problem with the instrument cluster, it started back in march when the speedo and tacho would stop working then restart after a few minutes,
it then progressed to the whole cluster going off and would for up to an hour, everything off except the warning lights.
Two days ago i went to start it but the battery was almost flat, once it started the speedo was sitting at 15mph at stop, don't know if it's just coincidence about the battery but it never given any bother before.
Just wanted to know i need another cluster or not.
