Touch screen doesn't light up

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.

With white screens it usually the LCD that went out, since D.S. do not have a reset button, the only way to reset it to Factory settings would be to remove that battery, and you would need to remove the little screws on the back. I would leave that last. However if you guys have had this DS for less than a year i would contact Nintendo, or go to the website
because you would still be under the one year Manufactures warranty. I would highly recommend to not state it was dropped. Just that the screen went blank all of a sudden. Touch screen works fine. Make sure there is no physical damage though, as that usually voids warranty. I had to do that for my Wii. No cost to me since under one year. If its been longer then the year then you could do the hard reset by removing the batter for a few mins.
Good Luck!

double check that both cable/ribbons are connected properly to the motherboard, the small thin ribbon which curls over the top of the motherboard is the one which powers and reads the touch screen so double check this!!
if this is all in fine then im sorry to say your touch screen is broken and will need replacing!

i think you should either get a new ds or tap the touch screen hard. if tapping the touch sreen harder does not work then that means it is time for a new ds.

The cable for the touchscreen is one with 4 conductors that connect directly to the overlay on the face of the LCD. The flat ribbon connector on the main board is quite delicate. The three connectors for the bottom screen are on the right side of the component side of the DS phat board. The touchscreen is labeled P6. On the DS Lite, the connector is closer to the R button.

Good Luck

try calibrating the touchscreen....

aparently fitting a new touchscreen works, i have just ordered one from ebay, cost me a tenner

try to recalibrate the touch screen.

turn on your DS

go to the SYSTEM OPTIONS

last available box, recalibrate.

i may be wrong, but try that anyways.

on the top right hand side of the screen just under the front there are four or five contact pads this is where the touch screen get the info from the touch screen to the ds itself if you have taken the ds apart maybe the pads are slightly out of line this can be fixed by applying light pressure to the pads to make them stick down and get a proper contact

I know you replaced both top and bottom, and I am assuming that you placed the touch screen as well? it would be the touchscreen that is not working or you did not connect right. connie
