Nissan Terrano 2003 cluster issues

The instrument cluster on my Terrano has had some issues, with some gauges not operating smoothly unless tapped, and some backlights missing. Before sending it to the mechanic it, I found out pressing both cluster buttons and turning the ignition key half way initiates self diagnostics mode. This is what is shown in the video, and you can clearly see the speedo is great, but all other gauges are whack. After this i decided to repair the cluster myself.
