I dont know what I should do. I bought this tv in april 2003 - therefore the warranty has run out. Out of the blue, the TV screen has a blue tint, the light dims on and off, and sometimes it turns black! Theres nothing wrong with the volume, so there might be hope. Is there anything I can do myself so that I dont have to pay an arm and a leg to get it evaluated/repaired? Please advise...
