So I just replaced the t-con board in my KDL-50W829B
Originally I had sound with no picture at all, replacing the t-con board gave me a fuzzy/yellowed image, I thought it might be the connections on the two ribbon cables so I unplugged one and I had a perfect picture on that side, the picture went wrong again.
Could this still be the connection (I've tried it several times) or could half the t-con board be dead? Is it possible that the input board for the panel is dead?
