We had a power outage and the next day all I could get on my TV was the blinking power light. Can you hellp me? I have a Samsung 42" LCD Flat Panel HDTV Model No. LN T4042N
Hi, the power surge has destroyed the power supply board that is located inside your lcd cabinet. this board works in conjunction with an inverter board that regulates the raw ac current that is used for many different functions in your set. Normally, this type of damage will be isolated within the power supply but, it could have spread to the main control board as well, depending on how well the surge protector preformed during the surge.
The good news is that, this is a repairable situation. you can replace the power supply circuit board and inverter board as well. these replacements will fix this issue.
please rate and god bless:)

Thank you for your help. As I was asleep at the time the power went out I do not know what happened. I will call the repair shop on Monday.
Did the power spike or did it sag or did both happen. ie: did the lights brighten and then dim and then go out ? I assume there is no reset button on the back of the set, the manual should describe ? Reason I ask is that different failures will occur depending on whether you had a surge or a dip or both. In anycase the unit is going to need experienced diagnostics and repair.
