Fault with its main board. Short circuited component/s at it. Contact any service technician; or the authorized service center. If you wish to get some details; check the site linked here. Surf the site with patience. Pull up older posts. http://electronicshelponline.blogspot.com/ . In most cases, the main board might have to be replaced. If so, a software [firmware] update too might be necessary.
the problem its the main board of the tv not the power supply board.the main one controls all your imputs tv av component etc the cheapest place to find it its at www.shopjimmy.com cheaper than the manufacturer and those dudes that you find online that charge an arm and a leg just to come and just repair your old main board mine as well buy a new one at this site for less ok and you are welcome
This problem happen to all the HDMI inputs?Only one HDMI input,that one properally is shorted.Might even the HDMI cable is old,and worn out.U have about 6 HDMI inputs on ur tv,rent about 3 DVDs movies and watches test out all ur HDMI ports out.
Samsung only makes TVs that last 2 years, mine also has the same problem. Throw it away and buy a cheaper disposable TV, despite all the hype Samsung is just another cheap and nasty manufacturer who uses its customers as product testers. Why do you think they keep changing model numbers every week ?
Try unplugging it for 30 mins. If it still has the problem, it may have when into protection mode.
When this happens, a part in the TV when bad. The protection mode keeps the TV from staying on to prevent further damage.
At this point, I would use the warranty on the TV. Being that it's only 6 months old.
Similar problem with an eleven and a half month old LT-40148. Approx. 1 inch vertical banding line on left side of screen on all inputs. After about two weeks, same problem on the right side of the screen.
Fortunately this occurred two weeks prior to the one year warranty expiring.
Called Mits customer service and they referred me to an authorized service center who I happened to have dealt with before.
They picked up the set. The front panel (LCD screen ) had to be replaced. Set was gone for two weeks as parts were not in stock. There was no charge. I hope this screen last more than a year.
