Mine is the same way,my orange light is bright but my LCD numbers are very light.
I was told to replace or rebuild
Rebuilt will cost about 350
Used one will cost about 200( how long will that one last)??????
What to do I haven't made my mind up yet.

I pushed on the hole that has the recessed photo sensor and the speedometer lit up. I had pushed hard for about 20 seconds with my thumb, the hole was covered so that no lite was getting in. It went out once and i pushed on the same spot and it been working ever since. something must be loose in there or the photo sensor is shakey. the spot on the dash where i am pushing i am not really touching the sensor just maybe putting pressure on it by pushing that spot on the dash. What a relief. Can that sensor be replaced?

Only goes to show how each situation is different. Some guys tap the dash top three or four times with their fist. Others drive down a bumpy road. Glad you found the potential culprit.
