Question about Nintendo DS Lite Console

Nintendo DS (F2 blown)

I blew F2 on BOTH of my son's units while trying to troubleshoot for an inop upper display on one unit.

I was in the process of changing the shells on both units because of broken hinges and thought I could find out if the problem with the inop upper display on one of the units was because of a bad display, ribbon cable or the main board. I guess I wasn't careful enough when I tried to connect the ribbon cable from the good unit into the the main board of the defective unit and then holding the battery in place while pressing the power button. I must have somehow allowed the metal case of the lower display to come in contact with the main PCB artwork.

I have ordered some new fuses from Mouser Electronics and hope there was no circuit damage caused by the short. I did check the resistance of F2 and found they were both open (yes, I tried to do the same test again with the other main board).

Since I can't continue to troubleshoot until the new fuses arrive and I replace them and test to see if the units power up when reassembled, do you feel it is more likely that the ribbon cable failed because of the broken hinge or do you think the problem is more likely the upper display is bad? I did notice that the upper display will sometimes flash a white screen before going black again when powered up with certain games installed.

Re: Nintendo DS (F2 blown)

STOP!!!!!!!!!! Read This first!!!!!!!!!!!!
Do not buy 0.5Amp fuses.
please read the marking on the fuse before you order your part.
(Picture below: zoomed in snapshot of "F1" for a DS LITE
Notice the Letter "H" right there in the middle?)
The 0603 size is the appropriate size ... on that you are all correct.
IEC has standardized the markings on SMD fuses!!!!! They are as follows:
Amepere Marking

500mA F
750mA G
1A H
1.5A K
2A N
2.5A O
3A P
3.5A R
4A S
5A T

Cooper/Bussman, Littelfuse, Panasonic, Shurter, Vishay/Beyschlay have all standardized their markings on their SMD fuses (IEC compliant).

so if you order please make sure you get one from any of these manufacturers or that their SMD fuses are IEC compliant. Their markings will be the same for the rating of the SMD fuse you want to replace.

In summary, for a DS Lite with F1 and F2 with an "H" marking buy an
0603 size, 1amp, fast blow fuse
Lead free? or not? ... thats up to you.

Happy fixin :)

Re: Nintendo DS (F2 blown)

Thanks gauss for your precious informations, but there are some motherboards that has diferent F1/F2 fuses. They are labeled as "32".
Please, see the photo below:

Is there anyone that can confirm they work exactly like the "H" fuse ?

If you're technical (can handle a soldering iron in a tight space) take a look at It'll tell you where the fuses are and which one is which but they don't tell you the values.

Re: Nintendo DS (F2 blown)

Hi -- my sons DS had a 750mA Fuse for F2 -- it's symbol is two small squares touching on the corner. See this data sheet for confirmation: They are about 80c each from Farnell...

Re: Nintendo DS (F2 blown)

Max1981... I am pretty certain the "32" on the fuse is the voltage rating. Although I agree the H on the fuse in Guass' unit is what se claims, my son's unit worked with the 0.5A fuses. Certainly a lower fuse value will not damage the Nintendo, it would just blow faster.

My son had not used his nintendo DS for some time but when he went to charge the battery, the light shined orange for a short while and then cut off.

I think its the fuse thats the problem. Try testing both the f1 and f2 fuses with a multimeter, chances are that one of the fuses have blown. Instead of replacing the fuses you can buy
a battery charger for the ds lite. search "Battery Charger for Nintendo dsl" on ebay It should
cost about $5.49

Ds lite comes on for a sec when charger plugged in then it goes of unit does not come on or charge

Hi three things come to mind, you dropped it but usually they wont admit it (dont go mad they usually all break when you do) if it rattles the capacitor under the power switch just fell off (common you have to solder it back on) if not that you replaced the bottom screen and forgot to insulate the metal of the back of the screen against the circuit board and blew either the f1 or f2 fuses (Replace them if you did) last thing i wont go into if you havent pulled it apart if you have reply and i will tell you Good Luck

My sons ds lite won't turn on - the screen flashes

hey there Mike to me it sounds like one of the ribbons inside became loose or there is a blown fuse in your unit both are fixable you can check the ribbons and also the fuse can be bridged as well if your unit is under warrenty please contact nintendo about this and get a RMA for the unit if it is not under warrenty then there is two solutions to this either get a repair tech to look at it "can be found in the fixya repair directory" or we can work it out together if you need to know the steps required to fix the unit.

DS Light Power Problem


You have a defective screen (probably the upper). Replace it with a new one or send it to Nintendo for repair.

Mr. Teacake,

Never...never..put a wet cartridge in the DS Lite. Even when it is left to dry. Water is funnest for avery electronic device. You made for almost 99% certain a short circuit and blown out the microfuse (F1 or F2) on the mainboard. It could be much worse but check F1 & F2 first. See Google for their locations

You turn de DS Lite on, the green light flashes and the unit turned of. Is that correct?

The DS Lite checks some things before he starts-up. One of these things are the screens. the DS sends a signal to it and expect an answer back. When this answer is not received, it shuts down.
The most common problem in these cases is the flatcable of the upper screen.
Question is, did you replaced the housing? If so, you might dammaged the flatcable of the upper screen. If not, the flatcable might be defective because of using the DS Lite a lot (open /close the unit).

So first check the flatcable of the upper screen (google and you will find manuals how to open the DS Lite but be carefull!!!!)

Second, on the mainboard are two fuses (F1 and F2) . Check these! One of them might be defective

Bummer. Sorry to hear this. Your console is broken and needs to be repaired. Contact Nintendo and arrange to have it repaired (or replaced if under warranty.)

DS Card Not Recognized

the card slot may be dusty, blow gently into it (making sure no spittle gets in) or get a clean cloth and wipe the outside of it. On no account must the slot get wet, or it will probably get damaged and will not work.
