I ' m hoping someone has an idea of what might be causing this problem ? My set is getting strange color distortion in horizontal chunks that move and disappear then reappear . It started out in HD sources only , but now shows up on SD sources as well . This happened about 6mos ago and I took the back off , removed the lamp and blew everything out w / compressed air .

Question: What is likely happening to my item in this passage ?
Answer: My TV is not outputting HD anymore which is why I bought it .My TV set is going out unfortunately I will have to buy a new one .None of the above choices .My world in minecraft has weird chunks appearing .
