Problem 4: “Image is Flickering or has Vertical Lines”

• Likely culprit: Bad solder joints on the LVDS connector or a failing timing controller (T-con) IC.
• Fix: Reflow the LVDS connector pins with a soldering iron. If that fails, the main IC (e.g., RTD2270) needs reballing – usually not worth the cost; replace the entire board.
