How can I fix my Phillips 60" big screen model 60pp9202/17f?

A repairman diagnosed my tv as a bad ss module for a service fee of $100. Total repair cost would be $560. We just spent $400 plus last year on this tv. My question is, can I purchase this part (#313503711212) and install it myself. Is it a matter of keeping track of all connections and just reconnecting, or is it more complicated than that.
