When all gauges fails, it should be a power supply fault and this might be something repairable.
Did Toyota remove the cluster to test or just informed you that the cluster is bad by looking at it?
You can get a cluster from the scrapyard which would be cheaper but the odometer would have to be recalibrated.
I do not have any diagrams to show on removal of the instrument cluster but it requires disabling the airbag system and removal of the driver's airbag and steering wheel.
Removal & Installation
1. Disable air bag system, remove driver's air bag and steering wheel. See AIR BAG RESTRAINT SYSTEMS article.
Remove steering column covers.
Remove instrument cluster finish panel. Remove holding screws and carefull pry it outwards, there are a few clps that might be a little stiff and requires some force, use a screw with tape would at tip to prevent damage to dash.
Note: If you think you got sufficient space to get the cluster finish without removing the steering wheel by lowering it to the maximum, skip removal of steering wheel and airbag.
2. Remove 4 instrument cluster retaining screws. Pull cluster outward far enough to disconnect wiring harness connectors. Remove instrument cluster. To install, reverse removal procedure.
