Report "Zenith tv turns itself off. like time after time. but if you have it disconnected from the satellite and just turn it on with no antenna it stays on will not turn itself off. i tried plugging it directly into the outlet and was same result. tv is more than 10 years old but has a really good picture. it also has a scribbly picture at the warm up time when it is going off. zenith tv not sure on the model #"
