Any particular samsung Tv? are you going to tell us or should we just guess?
Try reseating ALL the connectors check ALL fuses - small smd ones
on the tcon?
We can help a lot more if you please post good clear pictures of the whole chassis, and then pictures of each board, front and back and close up of connectors, (max resolution 2000x2000 and 2MB) using the manage attachments button, which is found by clicking "go advanced" under quick reply.
Please do not post inline and offsite as they slow down the loading of pages.
