In the 90's I sold Zenith (and other brand) tv's for a national retailer. As someone else said, Zenith is now nothing more than Lucky Goldstar. I used to cringe when I sold any Zenith products because they were such crap. I knew that a lot of the Zenith stuff I sold would come back as a return sooner or later.
In the early 2000's, I worked for a company that made circuit boards for Zenith tv's. The guys who worked for me always complained about how crappy the CAD specifications were that Zenith would send us. I can say firsthand that most specification disks they sent us always had viruses on them. My impression of them from working with them is that they didn't "have it totally together."
Personally, I wouldn't buy anything they make.
