Isolate where the problem is: it could be the LCD display or the graphics circuit on the main board. Connect the VGA output of the laptop to an external monitor - one that you know is good. From the function keys, activate the VGA output of the laptop - it's suppose to switch between the LCD display or to the external monitor. Switch it to the external monitor. If the external monitor works, then you have a problem with the LCD display of the laptop.
there is nothing wrong with your screen, the problem is from the flex that connects your screen to the phone's main board. This flex must have worn out that's why your screen is not displaying any picture.
The problem is common with flip and slide phones. The flex gets worn out as a result of constant opening and close of the flip or slide phone.
I would urge you to replace the flex and I am assuring you that your screen will display picture again. You might also be lucky to find out that the flex is not well fix, that is, it may have loosed contact.
If you cannot change the flex yourself, maybe you should take the phone to a local repairer within your vicinity, so that the flex can be fixed/replaced.
1. Make sure your phone is fully charged to handle the formatting process. 3. Turn off your n70. 4. Press and hold the following keys at the same time: a. Green dial key b. * or the star key. c. the no. 3 key
5. Press the power on to switch on the phone. Take note: Hold those keys until you see a formatting word on your screen.
6. Wait for a few minutes until formatting is completed.
There are no intensity adjustments I know of, and from my experience if the backlight is still working, but you get no display, it is either a bad display, or many times corrosion or a broken solder joint/component. I wish I could help you correct the problem with a few pushes of a button but not in this case. We do fix those models, you can check us out at www.cordlessrepair.com Thanks, CG
