It has had no previous problems but when I turned it on this morning there is no picture or sound no response from remote or controls on TV. The red light does blink twice when turned on but no other sign of activity.
OCP ( Over Current Protection ) 02 blinks. There is shorted component/s at its main board. Check it. For more information go to http://electronicshelponline.blogspot.com/ There is more information about the blinking codes, and fault locating ideas described, to many brand TVs. Pull up older posts.
SOURCE: No picture; No sound
how many times does it blink red? It should blink so many times then stop then blink again. how manty times does it cycle?

Mine started doing the same thing.
I turn power off (pull Plug) for a few seconds then try again.
Works OK but must perform unplug procedure each time.
SOURCE: Samsung TV won't turn on- trying to fix it. A challenging problem
I had the same problem. I live in NJ and called the local authorized "service provide" listed on the Samsung website. What a joke. Quoted $350 just to show up, never showed up. So I opened my own TV. Took off the plastic back (10 screws) took off the large metal RF shield (12-14 screws) and noticed a blown component. The markings on the component were KL15L and it is apparently an NTC Thermistor. Obviously it got fried and not knowing if there was other damage I decided to set out to replace the entire Power PCB Board Assembly and not the component. There were two part numbers on the assembled board (BN97-00457E & BN94-00622E). After searching online I also found a suitable replacement number for these (BN96-04896A). I found two places who claimed to have the part or have it on order (shopjimmy.com and vancebaldwin.com). After placing orders with both and having neither come through, I broadened my search and found out that the LNR409D was basically the same model as my LNR408D so I looked for its Power PCB Board Assembly part number which turned out to be BN41-00521B. Google search for that part number showed the item available on ebay. I bought it a week ago (ebay 260311519904) for $144 plus $12 shipping. I removed the bad board an hour ago (6 screws about 7 connectors) installed the new one, plugged in the connectors, replaced the covers, plugged in the TV... AND IT WORKS!
Suggestion: If your TV is out of warranty then open it up (what have you got to lose) and see if the problem is obvious and maybe something you can fix (replace) yourself. The parts, spare boards, etc. are out there if you look.
