Is this indicative of needing a new main board (assuming the t-con is part of this too)? suddenly occurred this evening after hanging on the wall for 4 years! have reseated all the cables, nothing obvious any advice welcome. thanks
You have 2 boards and the problem can be in either or the panel. That should make you happy. One board is strictly a power board, the other has everything else. If voltages are marked on the PSU verify they are all in spec. If not you have 2 choices. However, if neither fixes it, it is probably the panel, and it my not be economical to replace that. Try searching some Samsung forums.
