My two year old Sanyo dp50710 plasma hdtv will not power up

i came home one night to find my two year old sanyo dp50710 off and with no power. i checked power cord many times then tried looking for answers. after long search i found one blog and took off the back of tv to look for dead fuse. before searching for the fuse i noticed my logic board had some partially frayed wires running to it. could this be the problem and if so what do i do next?
