Hi.
Did a quick search, but did not find anything helpful. If there's an existing post, I apologize and please let me know. Thanks

My 3yr old Samsung LED UN50H6203AFXZA lost the picture, but still has sound and the backlight. I've changed the T-Con board with 2 others, changed the Main board and just changed the Power board last night, but nothing has worked.

What else can I do on my own? Should I try to replace the cables?

My 32" Samsung has not had any problems for 5+years, but am concerned if I should bother with another Samsung....

Any help would be appreciated!
Thanks!
