Why did it work before installation, now flashes numerous different colors?

Before installing replacement parts??? I can assume that the t-con board or the video board had terminal connectors or ribbon connectors. What is often overlooked is a misaligned connector or worse, a broken or bent pin. Try examining these connection points. You may have to use a magnifying glass. A defective screen usually goes black or produces broken images and/or color points. I hope this helps.

How do I hook an antenna to my tv

Hi Dwayne, The Proton has an NTSC analog tuner and also an ATSC digital tuner. Have you tried switching or changing the SOURCE inputs? You may also have to use the scan button to have the tuner "find" the channels for you once you determine that you have selected the correct source for the antenna. See page 9 of the manual. http://www.manualslib.com/manual/323457/Protron-Pltv-4250.html?page=17#manual
