This repair solution show the particular components and line paths of Nokia 1800 and Nokia 1616 Lcd display signals. This guide can be used for quick troubleshooting and repairing display problem issues on Nokia 1800 and Nokia 1616.
This repair guide shows on where and which particular components of the LCD data signal feeds across to a particular components, including even the solder ball bumps of the infeon X-gold 110 chip through to the LCD filter coils, resistors and LCD display module.
There are two LCD voltages that feeds to the LCD module, the 1.8 volts Dc which is in color pink line and the 2.8 volts which is in green line. The other four which are the display data signals.
This guide is useful when the display data filter coils and resistors already been replaced but the problem still exists. You can trace all of those corresponding line paths when the time that you need to remove, rework and even trying to replace a new IC
