I have 19in flat screen CRT monitor 3 years old. My monitor screen changes colour, when I move my data cable, connections are fine, looks like there is an internal damage to wires between the connector and the shield (in the cable).The cable on the monitor side is soldered inside the monitor.The only way to replace is to open the back of monitor.
Now my question is it worth replacing the data cable and how reliable is the performance afterwards.
