Answer 1

If the owners incorporated in Colorado, then the Colorado Secretary of State may have records.

Answer 2

If the company is called Television Tech., you can google the old name and see if any of the websites also give the new name.  Also you can write to the company's old address and ask if the company located there now was formerly known as Television Tech. Once you successfully locate the company, you can call or write them to find out what to do about lost stock certificates, but be very careful about who you give your stock/personal information to (you might want to go there in person if you live close by).
