Lightning storm came through the other night. My cable modem got hit as well as my Samsung TV. This is the second time this tv has been a victim of lightning. TV was plugged into a power strip, however I know that it does not matter. When I plug in the power cable to the back of the TV, the back light on the screen flashes for a split second. There is no red stand by light at any time. ( never flashes or attempts to come on) No response from the power button. I have opened the back of the TV, and checked for swollen caps, cracks in the board, burn marks, etc. Everything seems to be fine. No clicking noise or anything. The only possible indicator is the LED 2000 light blinks when the cable is plugged in. I have fixed this tv before when the lightning hit my cable STB and traveled through the HDMI cable and hit the component board (or whatever the correct term is) I would like to order a replacement part but I am not certain which part to order. I'm somewhat tech savvy and can use a multi meter if needed (used it last time) but I need to know the correct voltages and what to look for.

Hello
Lightning will have Trillion Trillions of volts, when it discharge to earth. Whatever type of surge protector we use, cannot withstand it. Even though other devices are safe, as you say, not the case of TV. The TV is connected direltly to mains supply voltage, even though it is in OFF state, there will be supply to the regulator board to keep one 5VDC supply, provided to work the memory and V-Chip section. Unless, all the memeory will go out, and you have to retune and reset the TV everytime you switch it ON. In fact, TVs power switching regulator side is working 24 hours a day. When lightning occurs, a sudden very high voltage, which cannot be suppressed by the surge protector [any surge protector in present market can supress upto 100 or 1500VAC peak the most]; and will get into the power supply section. Eventhough a trillionth part of a samm intensity lightning can damage the power retulator section, as it is designed to work in between 110 to 280VAC the most.
The power supply section inside your TV has now damaged. It is best to replace it as a catd basis, rather than making 'surgery' to it. Some other components in it also be got damged, as we cannot detect now, and will cause trouble in future, and make more "pocket leak' to you. So repalce it with same type and number, the number will be printed on its PCB. The orginal supply board can be had from Samsung Authrised Service center at your town. Just keep the board in hand as sample, when you go to buy a new one. OK.
That model is covered under a class actions lawsuit settlement over bad power supply boards. You need to contact Samsung about this and get a warranty claim started, even if the original warranty is over the settlement terms will cover parts and labor. You can get additional information about this along with contact information here: http://www.ccl-la.com/blog/index.php/samsung-has-reached-a-settlement-in-class-action-lawsuit-over-faulty-tv-power-supplies/
