How-to: Fix a Nintendo DS Lite that won’t turn on

14/09/2010

A while ago I dropped my DS Lite on the floor. It wasn’t a particularly long fall, but it landed completely flat, and it really didn’t sound good when it fell. Much to my dismay, after this incident it did not start again. Sliding the power switch did absolutely nothing. Trying to charge it there was no light at all, and it did not turn on with the charger plugged in. So I figured that I might as well open it up and take a look to see if perhaps it was something simple. I’m sure there are a number of things that can break when you drop your DS, so I can’t guarantee that this will work for you, but I did find this thread about a person having a similar issue.

Open it up
For opening the DS Lite, please go to this great thread over at GBAtemp. I followed the intructions and it was pretty easy. Just don’t make the same mistake I did and forget to take the Slot 2 card out of the DS before unscrewing the back, and remember you’ll need both a small phillips head and trigram screwdriver.

Diagnose
As soon as I took the backplate off, I noticed a little piece falling out – meet the resistor fuse!

This is a small surface-mounted component that had fallen off the PCB, and armed with that knowledge I started looking around trying to find where it once was. The hi-res photos of the DS Lite PCB over at the GBAtemp thread were of great help. After some time, I located the place of the component.

The fix
Since the component was very small (about 0.2-0.3cm in length) I was unsure if I would be able to solder it back onto the PCB directly, so I opted for the more cumbersom, but safer approach – soldering it to two pieces of wire and then soldering the wires to the PCB. Here’s how it turned out:

Wires, the component attached to them.

Close-up of joints on the PCB. Not the prettiest solder joints around, but considering the small size it’s still quite the accomplishment for me. 🙂

At this point I tried to turn the DS on by pressing the battery against the battery connectors on the back. If it turns back on, like mine did – congratulations, your joints are working and you’ve got the DS back to life!

Tidying it up
Using electrical tape, I affixed the component to the PCB to make sure it doesn’t wiggle around.

I actually had to go back after this picture and remove some tape because it was just so much that I could barely fit the backplate on. I also attached a tiny piece of tape between the connectors on the PCB, since I didn’t want them to short out if the cable twisted in some weird way.

Conclusion
Quite a fun project. This did take probably 4-5 hours with internet research, diagnosing and soldering, but it was very rewarding. Let me know if you’ve had this problem and the fix worked for you!

How-to: Dell 2209WA running at 75hz (or 76hz) and information regarding refresh rates

09/02/2010

2012-12-18 update: This tweak still works with Windows 8.

To use this on Windows 8 you will need to disable driver signature enforcements. This video will show you how to do it.
After that, right-click the .inf file and select Install.

Now go to:
Device Manager -> Monitor -> Dell 2209wa (or similar name) -> Properties -> Driver -> Update Driver -> Let me pick… -> Dell DELF011 (EDID Override)

Reboot and you’re all set!

I was surfing around the other day researching screen tearing and how it could be avoided, and stumbled upon a little driver hack that enables a faster refresh rate on this particular monitor. You can do it just as well with third-party applications like PowerStrip, but a native solution is great and enables you to use this higher mode only in games or certain applications, while maintaining the standard 60hz when you are using your computer for other things.

Please divert your eyes to the lower left corner!

So what’s the deal with faster refresh rates?
Faster refresh rates means you will get less screen tearing. It also heightens the response time of the monitor, allowing it to display information faster both normally and if vsync is enabled (going from 16.67 ms to 13.16 in response time.) It is also stated in the official specifications that the 75hz mode is supported.

Does it help?
I was a bit hesitant at first, but it really does! After toying around with it for a bit, the biggest difference turned out to be the timing I got when I  played DJ Max Trilogy; the result was very palpable, but i noticed that almost all games suffer much less from screen tearing while using 76hz.

Wolfenstein (2009) proved to be one of the best examples as it had some horrible tearing issues at 60hz which were all but gone at 76hz.

What if the game/application doesn’t let me select which mode to use or reverts to 60hz?
Many games have flags that you can send when starting it. If they don’t, a third party app might be able to force the refresh rate.

Download Dell2209wa76hz.zip

After unpacking, right-click the file you get and select “Install”. Please note that this fix is only for the Dell 2209WA monitor. Similar fixes may be available for your monitor, Google knows!

This does not alter any drivers you have installed for your graphics card, such as ATI Catalyst or nVidia GeForce.

A footnote regarding 75/76hz difference
I put both 75 and 76hz in the topic because there seems to be little difference between these two values and people use them interchangeably. After applying the driver mod my OSD shows 76hz which seems to work fine. I have not read any reports that this 1hz difference would be a problem.
