The flex cable between the display and the mainboard could be loose, try reconnecting it.

    probably the screen is faulty.

    you tried the broken screen on another n70 and it did the same thing? its faulty, would need to be replaced.

  • Ekse Jul 15, 2009

    Hard to say but if the display does the same thing on 2 phones, and the other phone works with its own display, then it must be that the display is faulty.

Why wont my asus a6000 wont power on. I took it apart and put it back together again and now it wont do anything cept the green light and the hardrive spinning. No fan and no screen activity.... Pleas

Sounds like it might have booted up especially when you say after 20 minutes the fan turned on. Maybe everything booted up and is running except your screen is black. You might have disconnected the LCD Cable when you pried the touchpad up to blow out dust. Try the steps below.

Shine a flashlight on the dark screen to see if you barely see the icons on the desktop. If so, then the LCD Inverter is bad.

Plug in an external monitor and see if the display shows up on it. It can be any kind of monitor even the old big fat crt monitors as long as it has a vga cable to connect to your computer's vga port. If so that proves your video card is ok. The video will show on most systems when you reboot without you having to do anything. Some systems will require you to hit the FN (Function key) + F1 thru F12. Hold down the FN key then hit the correct key for displaying on the monitor (F1 thru F12). The correct key will normally have CRT/LCD on it or it will have the icon of a display.

If you see no icons by shinning a flash light and the external monitor works, then your screen is bad. If you see no icons by shinning the flash light and nothing shows on the external monitor, then most likely your video card is bad.

We have sound but screen is black. can this be fixed?

If when you turn the TV on you see a brighter picture then your flat panel back light is working but the TV display mechanism is not. Most of the time this is not repairable by an end user though a specialty electronics shop may be able to repair it. If when you turn the TV on there is no noticeable brightening on the screen it could be that your TV is working but the back light has died. The back light on most TVs can be replaced but this is a fairly complex process involving taking the TV apart and swapping out the components.

Cell Phone on..key pad lighted and battery fuly charge but screen is blank


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.

Take care.

Help my screen doe not turn on!

Common failure of RAZR phones. It's not necessarily water damage. I have had two of them die on me that way - there's a very thin ribbon cable that connects the screen to the keypad and brain. Over time, flipping the phone open and closed damages that, and when it breaks, you lose your display. Unless you can micro-solder, you need a new phone.

Key Pad

Tiger, u gotta take ur phone apart, Using a torx screw driver (about 10 dollars at radio shack or walmart) and on the display side, remove the 4 screws with the torx screw driver, using some type of blade take apart the display, remove the connector with a knife or something really thin, and with some kinda brush (a tooth brush will work) brush the two sides of the connector since i m sure u ll see alot of moist in the same connector, and put it back together and that should fix ur problem.

it shows that you are having flex cable issues - common problem with the v3. you would have to bring it to a local repair shop or order a keypad flex and button flex cable to do yourself.
the parts are about $15-40 and a shop will charge about $25 to install

if all else fails contact me and we can help arrange it.

Key pad keys (other than on and off) dont work

Sounds like the keypad flex cable has gone bad ...your best bet is to take it to a serivce center unless you are comfortable taking the phone apart. The replacement cable it about 45.00 dollars US
