Not much. But I would prepare myself for the end. Almost all electronics you get today have 5 year design life spans. This is a little hard for some to accept but look around and there is little that gets 10 years old now.
I have had my 46 in lcd tv for 4 years. Recently, when the tv is initially turned on, there is a green screen that lasts about 5 seconds. I fear this is the begininng of the end. I had another lcd tv that started this way then died soon after. What does this mean?
