How to replace the screen?

I have a N770 with a defective touch screen. I have been told that it is a hardware problem and that it would require the screen being replaced. However, I haven't found any places selling replacement screens or offering replacing them as service. Former is actually preferred, as my budget for is quite small and I would not mind learning more about electronics.

Re: How to replace the screen?

Have you actually contacted Nokia ( Nokia offer international service and can even supply parts with instructions if pushed, although they will give you the impression that you have to buy service. Keep in mind that since the launch of the N800 some web retailers have dropped the price of N770's in stock to an average of arround £129, given that a replacement LCD will cost something close to this (or possibly more) anyway coupled with the fact that the N770 is still a very strong performer you may want to consider a new N770 instead. The N770 really is an outstanding product and it's custom micro-Linux build using matchbox UI amply shows just how poor Windows mobile actually is. It would be a shame to lose the device, however if you can't find a replacement screen or repair service perhaps this is a good excuse to upgrade to the N800. ;-)

The touchpad on my compaq pressario cq61 is not working at all the cursor has dissappeared from the screen, therefore i am unable to do anything on it as i do not have a mouse. please can you help

First, make sure that the device settings in Control Panel is set properly & that the touch pad is enabled. You might need to check these setting in the Mouse applet in Control Panel.

Next, if you suspect a corrupt driver, uninstall the driver, reboot the computer then re-install it again.

If this did not fix the problem, you might need to disassemble your laptop & make sure that the ribbon cable connecting the touch pad to the motherboard is not broken or loose. In order to do this, you will need to remove the keyboard & check beneath it where a thin ribbon cable connects the touch pad to the motherboard. Also, use an electric contact cleaner spray to clean both the contacts at the end of the ribbon cable & the connector to which the ribbon cable plugs.

If nothing of these helps, the touch pad might be defective & needs to be replaced. You can usually find a cheap replacement on Search with your laptop's make & model followed by the keywords "touch pad", & always buy from a top seller.

Scroll is not working

This could be one or some of the 3 issues that may be happening with your notebook or netbook:

1) check control panel (if this is windows) and click on touch pad icon and make sure the sofware to control the touch pad is working and it's on.

2) If it is on, reinstall all touch pad and mouse drivers for this unit by going to the manufature's website and downloading the original drivers for this unit

3) it that does not work, you may have a defective or broken touch pad and it may need replacing


They are usually the main causes of touch pad failure and should resolve your issue.

If both fails you may need to order a new part to replace the pad.

I hope this helps. Write me back and let me know how it goes

Nokia n770 white screen of death!

More than likely re-flashing your 770 with a fresh copy of it's operating system may fix your problem. This is a Cut/Paste from Nokia's site.

  1. Download the Nokia Internet Tablet Software Update Wizard and save it to your computer.
  2. Install the Nokia Internet Tablet Software Update Wizard by running Nokia_Internet_Tablet_Software_Update_Wizard.exe. This will install the update wizard and the Nokia USB cable driver if needed.
  3. To access the Nokia Internet Tablet Software Update Wizard on your computer, open the Start menu and select Programs > Nokia > Nokia Internet Tablet Software Update Wizard > Nokia Internet Tablet Software Update Wizard.
  4. Follow the instructions on screen to complete the software update.
Please note, you must have a USB cable to connect your 770 to the computer and the 770 must be fully charged and connected to the charger before you begin.

Hope this helps. It fixed a lot of problems I was having with mine.

White screen of death! on my nokia n770

Never take the battery out while it is still on even if frozen! Instead hold the power button down for 1 min until it reboots. Because the RAM logs the data to the processor. Also don't let your greasy fingers touch the pens on the battery or the inside connectors.
This messes up the pens on the batteries connector. I'd say gently clean the battery and connector pens with a dry clothe,and make sure to reset the device with the power button held for 1 minute. This should erase the image from the RAM. The Nokia 770 stores data in the internal RAM,so any errors are logged and a hard boot has to be done. Also only use software made for the OS not 2007 HE or 2008 HE.
