I recently swapped the tube on my K7000a Zenith chassis. The tubes were compatible, but I was weary about it from the start because the television was displaying in a slight purple tint. After putting the tube in, I got the color drives and cutoffs set the way they needed to be. The picture looks good aside from being too dark. When I raise the brightness, the green starts to turn blue. Is this because the green gun is too weak?
