Should I buy another flat screen now while they are still relatively cheap?

I highly recommend getting a Sony along with the related accessories. I finally learned my lesson after 30+ years of owning Samsung products that after 5 years or so you'll be watching something and the TV will go click, the screen will go dark and the set will go silent and you won't be able to get it going again. Yeah, and good luck contacting Samsung for support who will then after much trouble refer to a technical or repair facility that's hard to get to or when you contact them they will be vague and seem only interested in collecting their diagnostic fee with no guarantee of a remedy. Or in the case of our last Samsung TV, we had issues every time we made settings to the sound bar they would default to factory every time you turned it off and the bass would be set at maximum when you turned it back on. We constantly had issues with getting the TV, soundbar and the wireless bass module to sink so that it didn't look like you watching a Japanese Godzilla movie. Then after about a year random blacklines started to appear from the left side of the screen which severely obscured the picture. We gave it to Waste Management and bought a similar Sony system. Which looks and sounds better and has been completely reliable. I recently replaced my 20-year-old Pioneer BlueRay player with a Sony UBP-X800M2 4K UHD and I bet it too will last at least 20 years. Live and learn!
