If audio is OK; the back-light inverter should be checked and replaced. If audio too is absent, the main board is faulty. If you wish to get some details; visit the site linked here. Pull up older posts. Surf the site with patience. http://electronicshelponline.blogspot.com/

Very good chance it could have bad diodes. You will have to take the back off your TV and check to see if any have bad soder or need to be replaced
