    Bad main A/V board. Some people have had luck reflowing the solder joints under the processor (in a manner similar to Xbox 360 & PS3 repairs.)

        I have not done one of these myself, you would have to see the similar repairs for R73, N73 series Samsung LCD TV.

              it is not an easy done thing it needs a special tools so i think it is more likely better to find a new main board i think
