NT27E and 2701 use different yokes. Be sure you have the correct chassis yoke combination. To be sure, read the yoke part number and compare it to what Chad lists on his arcadecup site. Using the wrong chassis will result in you not being able to get the width correct, and or multiple failures of the HOT. I actually got a complete monitor once that had the wrong chassis on it. Took me a long time to figure out the problem.
