Screen white and touch screen not working

sounds like It is broken.
unless you get the startup screen beefore it goes out white i'd say something was damaged in the screen or the wiring connecting the screen to the unit.

If you see any lines on it, It was most likely over extended open and the wires inside have become frayed or damaged. If you try fully opening the top screen and push inward you may have temporary relief of this issue. could try puling out also but either way this would just be to test if thats the issue. dont pull or puch to hard as you could damage the unit further.

if it is a pure white screen the screen may have cracked or had something spilled on it which would damage the screen beyond use.

Either way, the system is damaged and needs to be replaced or repaired. Price wise it is more advisable to just buy a new unit rather then purchase parts and repair it.

This is what I told one personwho had a similar problem.

One time when my dinosoar of a ds was not a dino, I left it plugged in to the wall for a few days. When I went to unplug it and play a game that required the touch screen, it seemed to not know i was touching it. That night I went and bought mario bros. partners in time and played that game (which used buttons and not the screen) until my ds died and I recharged it only for a day and the touch screen worked again.

Another time I went to someones house with 2 little kids and let them play my game. They lost my pen ( and it was a hassel finding a pen small enough to fit in the slot) and started using their fingers. We ate some super buttery popcorn and kept touching the screen with our fingers. The next day the touch screen did not work and my step dad had to use windex 3 times daily for 2 days before it would work.

Make sure you try what I tried a few times. Pretty much any problem you have with the touch screen not responding can be fixed by letting your batteries run out of juice and recharging in a maximum time of 1 day. If this fails you, make sure you are using the bottom screen. You dont know how many people I have met that kept replacing their ds and ended up finding out they were using the wrong screen. Finally, replace the screen, and buttons or just replce the ds or dsi.

The bottom screen is made up of 2 parts the screen itself and the touch screen mambrane which sits on top of the screen, if the touch part is still woking then the screen is faulty and will need to be replaced.
There are some good videos on youtube that will run you through the process of changing just the screen.

Madam i think u should repair it because one of the touch screen sensors are broken so u have to repair it

A sign of the RROD send it to repairs.

Hi,
the cables need to be inserted Fully And squarely/evenly.
Also ensure The Tabs are locked Down correctly.
If none of this Works, you may have a blown On-Board Fuse.
I believe these Are Known As F1 And F2.

recalibrate the touch screen.

Well you can try getting a replacement from the store or try sending it in to nintendo.I doubt you can fix it.

A white line cannot be the Touchscreen. It must be the LCD screen under it. Could be a defective screen.

if he dropped it then the bottom should not show up as well. the bottom screen you can play the older games plus get instructions for the new games. if they are both out then it is the motherboard. if it is top only, it is the lcd screen and you can get that replaced for about $45. find a place to fix it or send it to nintendo. thanks, connie
