This website does show that warwick made TV's until '77.

I also read somewhere (can't remember where) that Sanyo bought them out and that in Warwick's last days, Sears canned them as a supplier because of quality control issues. The only other non-Sears product that I've seen that was warwick built were the Library of Congress talking book record players for the blind from the '60's. I've seen plenty of Sears radios, TVs, and stereos that were Warwick built. In fact, I have an early '60's silvertone portable transistor radio that was built by warwick and it's a good performer.
