Blank is a condition in which the mobile phone screen where there is no view at all. Or are the only lights up. LCD blank mobile phone is nothing strange, because this is the case that very often occur in every mobile phone. How do I improvement?
Perhaps for that has not experienced in the service will be confused where the direction and steps that must be done because every mobile phone has a different chart. For that we will criticize this case. But before we move further improve in, we will know the flow processes and procedures.
Blank damage caused by the LCD or damage in the LCD line can be interrupted flow path. This can be caused by corrosion of the remaining water and sediment formed prevent rust so that the flow of movement toward the LCD. It can also damage the components due to age factor components that are old, so vulnerable to damage. Blank can also because there is less foot components welled or cracked, so that some channels that the LCD does not work.
Blank divided type 2. We must first know the characteristics problem. Each have a solution and how to repair a different type of problem even though almost similar. If any, is not so mobile we get, but even increased fatal.
1. Blank can be turned off through the on-off
Make sure that the phone can receive calls to or phone service. If not, there is a possibility mobile phone signal is not there. This mobile phone should be turned off by pressing the button on / off. Not pull out the Battery.
2. Blank where to turn mobile phones should revoke Battery.
If the phone can not be turned off by pressing the button on / off can be said that a series of LCD is not problematic, but the mobile phone is entered in the category hangs, not blank.
Here we submit the steps to repair the Nokia N70 mobile phone screen is blank.
1. Open the case and check whether the mobile phone LCD conektor are connected properly. I just removed the LCD connector, clean with a toothbrush and cleaning fluids. (IPA). Then install it again. Blank could be less because only connect with the connector between the LCD.
2. If step 1 is still in trouble, try to test the LCD with the other. If only for the tests we can use the LCD type WD2 (6600.7610, N-Gage). May be caused by a damaged LCD. Should test the LCD before taking another step replacement or purchase a new LCD.
3. Solder re-foot connector LCD welded so easy. Use liquid Strong few feet on the connector, because it can only occur less welded lost on foot or connectors. Usually this happens because of concussion (fall) and welded must be done carefully because of the distance foot 2 feet 1 and is meeting once. May not happen united foot-leg lead by the plug because it will cause korslet.
If you have to do the above steps and still experience problems blank, then a series of note below. Under this component is the component that is very influential on the Nokia N70 mobile phone blank.
Description:
L: twist is that passive components shaped work for the desired flow.
C: Condensator is a component that works to save the cargo or the frequency of power supply in order to flow more stable and constant.
X: Conektor LCD is a link between the media 1 to the path of other objects between 1 to the other objects.
Z: Driver / Emif Filter (often spelled IC LCD) as the controller of the liquid so that liquid berpungsi in accordance with the data and the amount of cash issued by the software (program).
OMA: Processor (CPU) as the media is the process for display according to the program in accordance with the wishes brainware (men), If we look at the way this series of LCD display will have a 3 point heavy. We should note are the LCD connector, LCD Driver and OMAP. Which we do first? The answer is a risk component which is lighter.
Steps that must be made as follows. 1. Check the LCD and connectors with solder re disolser manual hot and sharp. When you need to be replaced because of damage this does not make mobile phones become a total dead. If there is severe damage to the mobile phone is still able to run other functions, not just a display on the screen. Pictures and location:
2. Check the LCD driver (as a voltage regulator controller to the LCD). This could be a driver or even unsolder is damaged. The solution reblow try to solder a little steam and digoyang to be more confident that the feet are connected with either. If you still can not, try to reprint the IC legs. If the problem also, just replaced this IC. Separah any damage to the components will not make mobile phones become a total dead and can still run function others. Such as phone calls, receive calls, not only have the display only. Pictures and location of IC for LCD display.
3. Check the condition of OC OMAP. But the damage is not clear on its IC. Usually the damage occurred on the leg-foot IC's. May have one foot in the IC unsolder or drop out. The solution we have to heat this IC. Not for the heat this IC better to ask for help or the partnership that has been experienced. Because of this IC are very sensitive and easily damaged if too hot. For this component of damage if any in pengerjaaan it will result in very fatal and can cause death total
