I tried the link you provided. It did not fixed the issue.
The fuses 1 , 43, and 45 are GOOD.

These are the steps from youtube about reseting the instrument cluster.
1. Key not in ignition
Remove fuses 1 / 43 / 45
2. Turn key to position 2, take out the key and put back
fuses 1 /43 /45
3. Start the car.

The speedometer does work so it can't be the fuses.
When it does not work, I make a left or right turn signal and the speedometer starts working right away.
