Hi,

I have a Samsung TV 48 inches, one day when I turned on the TV, only sound but no picture.  I really don’t know what happened.  I have replaced the t-con board.  The result was the same.  All of the back light is fully on.  I watched a few episodes on YouTube, it pointed to the display boards having problem, maybe smd ceramic capacitor/s?.  Can anyone help me to troubleshooting the TV to fix the no picture?

Thanks,
