sony kp 51ws 520 9 blinks

I have pulled the g board replaced 2 diodes 6301 and 6116 if I remember right put it back in made sure I had good connections tried it and still does the same thing did put it into self diagnosis and the zero crossing came up with a number everything else was zero tried clearing codes but same result nothing. Is it pretty easy to cook 6116 trying to solder it in place? This thing has me ready to take a sledgehammer to it   lol. I know you have gone through this with alot of other people but any advice you could give me would be great and also cay anyone send me a service manual for this thing. PS I am really starting to hate sony electronics.  Thanks for any help and/or advise anyone can give me .
