hi everybody, recently i have found that my tv has been making popping/clicking noises. i have a Scientific Atlanta Explorer 1840. i think its not the tv's problem because there is sound when i disconnect the tv and the 1840. this has been happening for quite some time now and usually goes back to normal after a few days. the popping noise replaces the sound of every channel so i am unable to enjoy watching tv. i dont use the 1840 to record shows because i dont know the function to do so. any body know whats happening and know a solution?
