help help help

I would like to repair my tv. I have a kdp-51ws550 sony, I have figured out what is wrong with it with the help of the service manual. but what I need to know now is? I want to make the repairs to the d-board but I dont want to get shocked either so can any one tell me if this is anything on the board that will shock me or anything that i might need to know before i remove it from the tv?
