Check the DC filter caps (caps with leaking/bulging top), cold solder joints.
If you are going to DIY and have proper tools and know safety precaution then please read on:
Most common failures in the LCD monitors are bad capacitors (bulging top/seal or leaking) in the power supply, blown fuses; poor solder joints, failed inverter circuits (blown fuse, shorted transistors, shorted/open transformers), bad lamps (poor solder connections or worn out lamps). You will need to open it up and inspect the inside, see example of failed monitors to get some ideas what to look for: http://s807.photobucket.com/home/budm/allalbums
Post back what you see inside so we can guide you further and it will help out other people in the future also.

Tip

DS Lite Top Screen Replacement


Hi,

Has your top screen devlouped a fault or stopped working altogether? Here is my guide to re-connecting a new top screen and fitting a new one.

Take the DS lite apart (a tri wing screwdriver is needed and can be found cheap on ebay), disconnect the top screen by lifiting the motherboards connector flap (located near the hindge) and then re-insert it, try switching it on again and see if thats sorted it. If not then you will need to replace the screen. (If you need help taking the DS lite apart then check out my other tips and tricks posted on here).

A new screen can be brought on ebay for a reasonable price, there will be a little soldering required as the speakers will need to be de-soldered from the old screen and re-soldered onto the new one (please take note of which wire goes where).

Remove the screws from the lid of the DS lite (4x screws hidden under little coloured squares above and below both speaker outlets) slide the top/outer part away from the hindges, it will move about 5mm and then you can lift it off... Gently pull the ribbon through the hindge so that it is free from the bottom part of the DS lite, pry the screen away from the shell (a small amount of force may be required to remove it) remove the front plastic part of the screen (with the respective DS lite coloured frame, de-solder the speakers, re-attatch them to the new screen, place the new screen into the housing along with the speakers and put back the wifi and mic to their original position if they got moved, you will notice a slot in the hindge where the ribbon goes in, this is for the ribbon to easily slide back into the bottom part of the DS lite... pop the ribbon through and then re-attatch it to the motherboard with the connector, pressing down the connectors flap.

Screw the DS lite back together, after this you will need to place the plastic sheet with the respective DS lite coloured frame back onto the top screen... The reason you don't put it on any time before that is if you put it on prior to putting the new screen in place you will have great difficulty trying to get it correctly aligned.

If you find that your DS lite now doesn't want to stay powered on please refer to my other tips and tricks I have issued on here.

I hope this helps and have to say that I accept no responsability for any damage that may occur to your DS lite when following these tips.

Regards,

Second screen goes on and off, Works for a while


Ok. Maybe you need to charge the Nintendo DS Lite or you might have hit the bottom surface really hard that it hit the touch screen's body in the back.

Top screen goes opaque white, but looks fine with pressed L button.


Puchigusu,

You have a defective flatcable of the upper screen, or the calble is not correct seated in the connector on the systemboard.
The upper screen connector is on the bottom side of the Left button-switch.

If the flatcable is defective (most likely because of the open-close actions every time the DS Lite is used) you have to replace the complete upper screen (the cable cannot be removed without replacing the whole screen).

First try to reseat the flatcable in the connector. If that is not working, replace the screen (manuals how to open the DS Lite etc etc can be found on the Internet)
