Tip & How-To about Cell Phones

Hi, Has your bottom screen developed a fault or stopped working? Has your touch screen become less responsive or stopped working altogether or just has a few too many scratches? Then here are some tips to help you get your DS lite back to full health. To replace the bottom and/or touch screen you will need a precision "+" cross-head screwdriver and a precision tri-wing screwdriver which can both be purchased on ebay for a reasonable fee. The respective screens can also be purchased on ebay for a reasonable fee. Firstly you will need to remove the battery cover and battery, unscrew the cover with the cross-head screwdriver, leaver it off either with a thin blade or similar, and take out the battery. Next you need to remove the remaining 3 cross-head screws, 1- top right corner of the battery compartment, 2 & 3- underneath the rubber feet along the hindge (note that screws 2 & 3 are of a gold colour). Now you will need to remove the 4 tri-wing screws which are located 1- top left of the main body, 2- bottom left of the main body, 3- bottom right corner in the battery compartment and 4- in the top centre of the "slot- 1" hole (note this is a small black tri-wing screw). You can now remove the back of the DS lite, be careul as there are springs and rods located on both trigger/shoulder buttons which can easily get lost (if you do somehow manage to lose them they can be replaced with another trip to ebay). Remove bother the trigger/shoulder buttons along with the rods and springs, if you can keep them together as a unit so that they can be easily fitted back on without having to fiddle about aligning the spring, shoulder button holes and rods. Next you need to remove the 2 cross-head screws holding the main board into place, these are a different size to the others so try keep them seperate. Now you need to disconnect the top screens ribbon from the board by lifting the flap of the connector and then gently pulling the ribbon free, gently pop of the mic cable (white cable) and the wi-fi cable (black cable) and slide out the wif-fi one from under the "slot-1" component so that the motherboard is free from the rest of the DS lite. Just above where the w-fi cable was connected to the motherboard you will see a very small connector and ribbon, this is for the touch screen, carefully lift the flap and remove the ribbon, if its the touch screen thats the problen try re-connecting it and then giving it a power up to test it, if it doesn't make a difference then a replacement is needed. Flip the motherboard over and you will see where the bottom screens ribbon is attatched, as before you need to lift the flap and remove it, if you want to test a re-connection then give it a go, if it doesn't work then a replacement will be needed. I have found that when trying to seperate the touch screen fron the LCD screen the touch screen becomes collateral damage as the force of pulling them apart tends to be too much for it so chances are you will end up replacing it (though you never know you might be lucky). So anyway, whatever screen you are replacing you need to seperate them and dispose of the faluty one,replacing it with the new one and either use thin strips of double sided tape to re-attach them (take note of the original screens position to perfectly mimic it) or just place them one on top of the other, as the shell casing should hold them into place. Now all you need to do is the reversal of the taking apart process remembering to slot the spring back into the groves so they have tension and you are all sorted. (If you have dificulty feeding the wi-fi cable back under the "slot-1" component first try straighteningthe wire, if that don't work get a needle and thread, tie the thread to the end of the cable, let the needle fall through behind the "slot-1" component and then gently pull and wiggle through). If you now find that you DS lite does not power on or has the green light flash when powered on please see my other tips and trick I have posted on here. I hope this helps and have to say that I accept no responsability forany damage that may occur to your DS lite when following these tips. Regards, SOD69

screen touch not working


Clean the touch screen on the phone with an electronics cleaning cloth or wipe. Dirt, dust and oils from your fingertips can collect on the screen, making it unresponsive or desensitized to your finger's touch. Clean the screen in a circular motion.

Eliminate any bubbles under the screen protector. You can do this by removing the screen protector and then reapplying it, going from the top of the screen to the bottom or vice versa.

Remove the screen protector and do not place the protector back on the touch screen. Screen protectors are made for protecting a touch screen, but sometimes the protectors make the touch screen less responsive to your finger touch or even altogether unresponsive.

Power off the touch screen phone if the touch screen stops working when a new program is opened. This isn't a problem with the touch screen, but a problem with the software trying to load or open on the phone. Some programs can slow response time with the touch screen or may not respond to it at all.

Acer n30 Screen Tap Freeze

Sounds as if the touch screen membrane is defective, which is a darned nuisance, but not impossible to fix .... if you are confident of dismantling the n30, you can buy a new touch screen membrane from Ebay for about 4 pounds/6 dollars.
It is a very skilful job to remove the old touch membrane from the actual display screen below it, not really for a novice, and all internal components are very delicate, so i suggest you find a tame technician before you buy the new membrane. The touch membrane connects to the motherboard via a tiny flexible 4 or 5 pin membrane ribbon cable, it's a miracle of miniature engineering inside the n30, so do ve very careful if you decide to do it yourself, best of luck!
