Samsung LN32A550 - 5 Series
I have static vertical lines (1 pixel in size) that goes straight down on the right side of the TV. They usually disappear after the set is on for a few minutes but recently they are constantly there.
When the set is first turn on, there is quite a few but after a minute or so, only 3 - 4 lines remand.
I tried the following solutions:
1.Lightly tap on the bottom right side which causes one or two of them to go away.
2.Reconnected all the cables to the TCON board. If my TCON board was faulty, there would be a really mess up picture instead of a vertical line.
3.Tighten the screws from the PCB to the Logic board, nothing happen as the problem persist.
Solutions from other people:
I been told that I need to replace or tighten the ribbon cables that are around the set. One person told me that it must only be done by a professional as any slight damage will ruin the set. Another person told me I needed to take off the bezel and apply electric tape to the loose cable.
This set has served me well, it is nearly 5 years old and if the risk is too high, I will just live with the random vertical lines at the side.
Here is the picture
