Our 50" Vizio TV keeps taking short breaks - no picture and no sound for several seconds. I'm guessing we'll have to replace it. Looking online, I see an assortment of 50" Vizio TVs. They don't make the differences between them obvious. Decisions, decisions. You'd think they could make the choices easier. I'll have to check out other brands, too.
Jerry, before you buy a new TV, are you sure you have a TV problem? Digital TV set top boxes used for cable and satellite TV rely on buffering. If your signal source is weak, the buffering can get too slow for the demand for data. This can cause the signal to freeze, drop out, or glitch some way.
I would test the set with more than one other signal source to see if the problem persists.
Here's my experience, for what it is worth.
I live in a neighborhood that was built in the 1990s. The cable lines on the poles are pretty old. The drops to the houses are pretty old. When we first moved here in 2014, service was adequate. three years later, we started seeing signal dropouts — not just with TV, but with Internet connectivity. I called the cable company and complained, and they sent out a really good technician. He found:
Corroded connectors at the junction box on the utility pole (he replaced them)
Breaks in the insulation of the 20-year old line from the pole across the street to a pole in our front yard (He replaced that line)
Corroded connectors at the "drip loop" on the bottom of the phone pole in our front yard where the cable runs into the ground to run up to the house (Replaced)
Corroded connectors in the junction box on the side of the house. (Replaced)
Bad connectors where the cable met the four-way signal distribution amplifier. (Replaced)
Bad connector on the modem line (Replaced)
After that, our system was flawless for a year. Then our distribution amp got fried in a storm, and they had to replace that.
If you have an RF input on your TV, and an over-the-air antenna, try re-orienting the antenna toward the towers of your local stations. Those things are usually wall-mounted or window-mounted plates that are pretty directional.
If the problem persists after testing, it's time for a new set. Unfortunately, it is very hard or impossible to find repair services for modern TVs.
Consumer Reports tests TVs every year. I'd join their web site just to be sure you get the best set you can.
