Due to an alert that the "3rd wave" DS lites can not be flashed and a way to test was to touch the S1 with metal and the DS would shut down.
I did this test several times to be sure that the ds lite would not "brick" during the process with different items.
I tried with an aluminium foil wrapped around a tooth pick and moving it around a bit, it turned off!
I tested this to confirm a few times and after one too many tries, the DS wouldn't turn back on again.
I got worried after this but I did not have my charger at the time.

My charger has now arrived and i plugged it in.
The charge light comes on then turns off..

Would I have to open my ds lite to check the area near the S1 connection for bits of foil or have i shorted my ds lite?

Any advice would be greatly appreciated

Edit: The battery was low as the red light was on during the tests. But again, I was able to turn on the Lite after a few tests..but the last one it shut off for good

thanks for the quick reply
sorry i should've read that post more carefully
i'll try to take apart my ds lite and see if i can find the problem

If we try to power up the DS with only the battery nothing happens (no light).  If we plug in the AC adapter the DS will blink orange for a second then nothing.  If we press the power button while the light is still orange the light will sometimes change to green for a second (speaker may chirp also) then nothing.

The power light might also change to red if the battery is low.  Otherwise, does your DSlite exhibit the same symptoms?

The DSlite has a different PCB layout than the old DS, but my guess is the fuses are still marked F1 and F2.  I used a multi meter to test both fuses and found F2 to be blown.  It may be F1 in your case? I purchased a tri-wing screwdriver on eBay to open the DS.  To fix the DS I used a small bit of wire and solder to bridge the fuse in question.  The DS works perfectly now. Good luck.

According to your previous topic - yes my lite has the same symptoms
When i plug it in, there's an orange light, when i try to turn it on while orange - it turns green then switches off

I'm trying to locate the fuses but it's definetely hard
i found some images here

Also..taking it apart is a pain because i don't have the appropriate screwdriver at home >< I'm going to go into my university tomorrow and try to take it apart n test the fuses there...if i can find them

I clearly see F1 near the power connector.

I've ordered my screwdriver from ebay and i'm currently waiting it...
I'm just wondering what kind of wire did you use for your fuse, bitblt?
could i use a copper wire, coat it in solder and fix it on? or is there a specific sort of fuse wire i should use?

I really hope this can fix my DS lite..otherwise I might have to wait for another order from Japan or wait til june..

He's just saying temporarily connect a wire which would remove the function of the fuse but would also reconnect the circuit.  And if it goes haywire again, or if you short it out again, you could totally bake some other component.  The fuse is just a weak point in the connection, it blows to protect the other parts.  (I think)

[daiakuji]

i figured as much about wiring up the fuse to bridge the connection but i was wondering if there's any material reccomendation to reduce the chance of a smoking hot (even though it is pretty sexy XD) ds lite

also would it be safe to play the fixed ds while connected to the power outlet?

Sorry i'm just slightly worried about the circuit board now..i don't want to fry it because i still have to flash it for supercard...

I'll probably use the paper method to block off the battery pads..

Thanks for the confirmation socket

Oh, I see... I understand your question now... I'm not sure... maybe there is some kind of weak fuse wire... i really have no idea.

I really have no idea either.  I do know exactly why my DS shorted so I didn't bother replacing the fuse. :shock: (living on the edge)

I started with a one inch piece of the  smallest gauge wire I could find.  I removed the plastic insulation to reveal the thin wire strands inside, and then carefully removed one single wire fiber.  Then I soldered one end of the wire fiber to one fuse contact, trimmed the excess wire, and finally soldered the other end to the other fuse contact.  The wire I was using was silver in color (tin?) and was key to preventing the solder from forming beads.  Also, be very careful not to get solder on any other circuitry.

just get 30guage single core...

i popped open the DS lite today and found to my disappointment that there is no F1 or F2 bridge
Either that or I can't see it
If you're looking at the circuit board posted above, the gold points next to it is occupied by some thing which looks similar to a resistor..
unless..this is the fuse "box"?
could i get any ideas/info please?
Also i noticed someone here said he blew something on the board but fixed it..i don't think he's come back since =\

Edit: nvm, it would appear that it is the fuse..according to the other post by bitblt
i'm going to have to get some materials before attempting to fix it
Did you remove the component? or just wire over it?

Edit 2: there's a wire near the top of the component..argh gonna be a pain if i get that melted =\ also hard to remove because it goes under the ds slot

Don't mess with anything else but the little black fuse "box" F1 or F2.  Use a mutimeter to test them.  Don't mess with any other DS wires.  Just find a bit of old wire (from something else) and solder (bridge) the fuse in question.  Don't get solder on anything but the fuse. . .

just get 30guage single core...

EDIT:
This picture shows F2 in DSlite and is usually the problem fuse . . .
