Color Distortion: This is usually an LVDS map issue, also fixable in the Service Menu under "TI Mode" or "Bit Depth."

Q: What if I cannot find any official firmware link?
A: The device may be end-of-life (EOL). In that case, isolate it from untrusted networks or replace it with a modern alternative. Never use unverified firmware from unknown sources.
