My nintendo ds lite when you power it on, it will not stay on. The screen will flash and then it will shut off.

Hello there! First of all let me tell you that your nintendo ds can be repaired and it is not trash... what you need is to get the bottom screen to be repaired ....you can do it sending it to the nintendo repair shop or by doing it yourself by following this youtube guide http://www.youtube.com/user/nintendorepair.

Hi the solution to your problem is
A failed top screen the ribbon had gone
The green light comes on screen flashes an then goes off
I repair nintendo ds lites in the uk
So can sort you out for a reasonable price

When you power the unit on, watch to see if either screen flashes. It's a very quick white flash. If that happens, the LCD that DIDN'T flash is bad and needs to be replaced. The unit will shut off immediately afterwards. If the unit stays on but there is no display on either screen, the board is bad and the unit is scrap unless you want to disassemble and reflow. This is a rare problem but it does happen.

you probably have a power shortage when you move the screen. the only way to fix this is to open the ds, make sure everything is in the right place, and put it back together. i cant promise this will work, but it should.

One or both your screens have blown.

Try removing the motherboard from the screens and attach the battery the green light should turn on and stay on.

Now attach the lower screen and turn on. If the screen is ok the screen and green light will flash and then turn off. (if the screen doesn't flash the bottom screen is you're problem and will have to be replaced)

If this happens the problem is then you're top screen which you will have to replace.

I think if the orange light flashes once it means it has a full charge.

the nintendo DS IS A *******!!!!!!!!!!!!!!!!! PIECE OF **** YOU ******* ****

Baakie,

You turn de DS Lite on, the green light flashes and the unit turned of. Is that correct?

The DS Lite checks some things before he starts-up. One of these things are the screens. the DS sends a signal to it and expect an answer back. When this answer is not received, it shuts down.
The most common problem in these cases is the flatcable of the upper screen.
Question is, did you replaced the housing? If so, you might dammaged the flatcable of the upper screen. If not, the flatcable might be defective because of using the DS Lite a lot (open /close the unit).

So first check the flatcable of the upper screen (google and you will find manuals how to open the DS Lite but be carefull!!!!)

Second, on the mainboard are two fuses (F1 and F2) . Check these! One of them might be defective

Success

Not necessarily. When the cable to my top screen became partially torn, it prevented the DS from powering up. Instead, the green light briefly lit up and then went out and the machine stayed off. I can only presume that feedback is required from the screen. As for the bottom screen, I'm unsure of how the DS behaves when the screen or cable is damaged.

Hope this helps.
