Question about Nintendo 3ds Handheld Game Console- Cosmo Black for DS
If it is the 3ds (which is different from the ds lite and dsi), then see which screen flashes before the popping sound. The one that flash is working. The other that stays dark is not getting power. The fact that you hear the popping sound tells you that the speakers are working.
If the bottom lcd flashes, then issue is related to the top lcd. The top lcd is connected to 3d/speaker cable. That means the top lcd may be fine but the issue is with the 3d cable. Open the back of the 3ds and check the connection 3d cable to the motherboard. (carefully because the screws are thin and can be stripped). Then open the top half (carefully because the black cover is glue on to access the screws to remove the other cover. Check the top lcd connections to the other ribbon. If they are loose, then refasten them. This is the best option because it is simple repair. Just be careful not to bend the pins. If you see any damage (i.e. tears, broken clasps), then those parts will need to be replaced. It is easier to replace the cable or the lcd, motherboard replacement is not enjoyable.

First check the battery and see if it's not the problem. If you can borrow a known working battery from friend etc. and it still does not power on it's probably a microfuse that's blown and you should have it repaired by a professional

most likely its the top screen ribbon.Because when you open the ds all the way it might push the ribbon in just enough to be read but when not open it cant read the top screen and it will shut down.I have instructions on how to change a top screen you can use them to put the ribbon back in. the only difference is you don't need to unplug the white and black wires.First you need a tri wing screwdriver and a cross screwdriver.You can get both on ebay.Then their are seven screws four tri wing and three cross.You will need to pry the back off be very careful.Start on the side that doesn't have the on off switch and work your way around.Once you have the back off unscrew the two cross screws that hold the logic board on.Then unplug the white and black wifi and mic wires they snap on and off.Then flip the logic board over by pushing the bottom screen out.On the other side is where the ribbon for the top screen is.To get the hinge apart their are two more cross screws in the top left corner take them out that releases the hinge.very carefully roll the ribbon so you can get it through the metal ring and the wires pull the wires first.to get the top apart the four cross screws are above and below the speakers under those small squares.A needle will get them out easily .Once you get the screws out then slid the back of the top up 1/8 of an inch then pull the back off carefully.You need to push the screen out and unsolder the speaker wires or use new ones.Make sure when putting it back together you roll the new ribbon the right way look at the old one to find out .Getting the old ribbon out and the new one in is a little difficult so take it all apart first and get the wires out then the ribbon and put the ribbon in first.

HI, the power sector has failed in your unit. this will cause the issues you are experiencing at this time. you will need to contact Nintendo at this time. they will issue you a repair ticket so that this unit can be repair. the power sector will need to be replaced(Power component failure).

I'll quote GBATemp here:
the ds lite powers up for a brief instant, but then shuts off
disassemble the lower shell and check the connections of upper and lower displays (all three flexible cable connections).
