    After reading other posts, It blinks 10 times. I unplugged tht red connector with blue wires going to the one board (convergence?) and the tv powered up with a 3D looking picture.

    Thank you. I took the board to a local tv shop and they soldered the two new STK392-040 chips in and all is fine now! $73 total!

You will need to locate the convergence amp IC's, the STK392-040, and replace both of them. The originals IC's can be ordered here http://www.mcminone.com/search.asp?keyword=STK392-040&btnSubmit.x=4&btnSubmit.y=6 Good Luck
