I'm not even entirely sure what chassis I have but I think it's a 7500. I'm having trouble with I'm pretty sure is the sync on my maximum force, the original monitor I had in here was going dim even after a cap kit so we switched out the entire monitor but now we just get this.
did you not have the remote board plugged in? that should give you vertical collapse but the U2000 was a little different than the others in many ways than one. lol
