Re: Samsung PN51D550 unable to power on

I have this blinking/clicking/not turning on problem with my three year old PS51D550 (full model number PS51D550C1RLXL version I409). A technician looked at it and concluded that the 50DH/DF Y-Main PCB LJ41-09423A part is faulty. He has been unable to locate a replacement part here in India, but I see a bunch of places online offering it. However, those parts are Rev. 1.3, whereas my current faulty board is Rev 1.4. Some are even older 1.0s, and some places are offering newer 1.5s, but I don't think they ship to India.

My question...
