I live in winter climate and have a 15 year old energy sucking plasma TV. My take is it revenue neutral. I only watch it for a few hours a day. It cranks out some heat which comes in handy in the winter, but does increase AC usage in the summer. The picture is still great, so no reason to buy a new one. Most of the light bulbs in my house are LEDs
Yeah, some sets just have an unbeatable picture. My Samsung 46” LCD I bought for 4700 from Best Buy in 2007 has an awesome picture. The Ex is still using it. Power hungry tho and cranks out heat. I bought an LG 3D to replace it but picture is not as good. Much less power and heat from it tho.
I would walk thru a big box store and check which LED models have the best picture. Then look online for a good price and have it shipped. Almost all are under a grand. That plasma could seriously hurt someone if it fell on them. : ) I’d use a wood stove to replace the heat.
If it is 15 years old you are getting a lousy picture by todays standards. Seventy five inch TVs can be had for $500.00 maybe less since 85 is becoming the new standard. The cheaper ones are the ROKU or other smart TV options but you don't have to let them be smart just don't connect them to the internet. I use them as computer monitors and let the computer handle the smart part.
