Nokia 5530 Xpress Music Lcd Solution
Learn also for fix : Nokia 5130 LCD Display jumper ways solution
Here's the LCD Display line paths tracing guide for heavy a and deep
troubleshooting Nokia 5130 LCD Screen Display problem such white screen,
blue screen, blank or black screen, garbled and saturated screen
displays. This solution shows the exact location where each
corresponding LCD pin connector connected to a particular components for
easy line tracing procedures.
This first solution shows the voltage supply to the LCD display module that feeds to the pin connector. You may check, trace this particular voltages first.this also includes the LCD display backlight LED corresponding current and voltage pin configuration. If this voltages are not present this will also result to display problem issues.
And this solution corresponds to each and every LCD display data signals connection to the pin connector that being feeds from the application processor (CPU IC) through to the LCD display module.
All these lines is connected to an Filter chip resistors that have a resistance value of 33 ohms per each resistor.You may check, trace, replace this particular chip resistor if found damaged. And if found an open line paths, just try to manage applying a jumper wire on it for that is the only option.
