You'll need a service manual if the internet doesn't have that blink code. You can get the service manual for many models at samsungparts.com and I see shopjimmy.com has expanded some board repair kits.
Last week my Samsung Tv suddenly stopped working and i replaced the whole power supply board after figuring out the problem. it has worked fine all week until today when i unplugged my cable box from the powerstrip that my tv was plugged into. Now the tv wont turn on and the red standby light blinks every once in a while.
