My nintendo ds i has both screens blank and doesn't turn off and the lights are not doing anything what can i do?

I would suggest to go to Fred Meyer or an equivalant store and go to the electronics section. Find a new DS Lite battery.

Needs new LCD screen - try www.dsdoctor.co.uk

possible that the flex holding the lcd is broken.

Last DS I had that did this was fried and I binned it. I tried all sorts of motherboard repairs but it just didn't affect anything. If it's that new just send it back for replacement.

ur ds froze or it did not turn on all the way.Take it to Game Stop

if its one of the micro sd card action replay you can try to format it.make sure you get all of the data off for this take it back to the first time you got it from the store.

it may be dead, or just doesnt work anymore.

Nope this is a screen problem. Get them replaced!

well you could charge your ds and whil its charging you can turn it on

This definatley sounds faulty. Try turning it on again without any games inside. If it turns on okay without a game then it may just be that game you had inserted into it, if this is the case then try a different game to determine whether it is the game or not. If the screen still remains blank then take the DS back to the store where you purchased it and they should replace it free for another one.
