There is a class action law suit on this issue. Contact Samsung. Sometimes they will send a tech, sometimes you get a runaround. If you get the runaround, ask if you need to join the lawsuit. Just Google "Samsung TV & class action law suit" for information on it. It has to do with two underrated capacitors and they won't tell me which ones. I got the runaround including sending me back to the same phone number I was talking to them on.
