Cold weather = Horizontal lines
Hello, I put an older tv in the garage, a 65" RCA smart TV Virtuoso which works fine in the summer days but when the temperature drops to like 65F or lower I get a lot of horizontal lines going up and down that I cannot see the image anymore. When the weather warms up it's fine again. Could it be the t-con board???
Did you figure out what was the problem, i have same issue, same tv

The issue is definitely one of the boards that cannot handle a tiny drop in temperature. If the temperature in the garage drops below 80F the lines gradually appear. I direct a small heater behind the TV and the lines go away. Any weather above 80F and the TV works perfectly fine. Somebody had replied that one way to check which board is to remove the back cover, turn it on when either the indoor or outdoor temperature is above 80F and spray keyboard cleaner which is cold on one board at a time. That should tell you which board is faulty. I haven't had a chance to do that yet.
