Nokia 2710 Blank Black and White Screen Display Problem Solution
Heres the solution which covers and possibly help fix nokia 2710 navigation edition Display problems such as blank or black Lcd, blue Lcd, white Lcd, garbled and saturated Lcd display problems.
If ever encountered this kind of problem you may first try to update or restore the device firmware first, and then try to install a new replacement LCD Lcd module.
If all of the above already been done but still the problem still exists, you may then used tjis solution below for hardware troubleshooting procedure on Nokia 2710 PCB board.
You may start checking up the nokia 2710 LCD pin connector, ensure that is absolutely clean.
There are two resistors mounted at the bottom of it, check this two resistors resistance value for it holds the display data signals through to the LCD Lcd. Replace if found damaged.
Check also the LCD Lcd module supply voltages, these are 2.8 and 1.8 volts.
If both resistors and supply voltages were okay, you may then suspects that the problem lies on the JUNO chip. Reworking this chip might possibly fix and repair Nokia 2710 display problem issues.

Nokia X6 Touch Screen Problem Solution
If ever trying to fix Nokia X6 touch Lcd failure issues and youll do replacing the touch plate module, trying to calibrate the touch Lcd setting but unresponsive and restoring, upgrading and flashing the device firmware but nothing happens, the problem still exist and the touch Lcd left unresponsive.
This sometimes happens if the device suffered due to a wet damaged, heavily dropped and any related damaged accidentally done by the user. In this case only a hardware repair may only help solved the problem.
This solution below show the Nokia X6 PCB board components that holds and control the touch Lcd panel to work.
The solution above showed a Touch Accelerometer chip that used to sense orientation, detect direction in multi-access direction of the Touch Plate module. If the chip is damaged the touch Lcd will not work and remains unresponsive. This chip needs a DC supply voltage of 2.78 volts in this designed on Nokia X6 and also. The 2.78 Dc volts is also feeds and supply the touch plate module.
You may check this supply voltage first before trying to rework, re-ball or replacing the touch accelerometer chip.
