Speedometer not working correctly

[khevion]

Hi,

The speedometer of my 1993 Toyota Corolla is not working properly. It would stuck at 0 when I start driving it. Then about 10 minutes or so later it would suddenly rapidly go all the way to about 55 mph. If then I press on the brake gently or otherwise it would quickly go all the way down to 0 and stuck there and the cycle repeat about every 10 minutes. What is the most likely cause of the problem? Does it look like I need to replace the instrumentation cluster?

Thanks in advance for your insight.
