"turn on and then immediately off"에 답변Hi, if you’ve got no flash screen, consider to try my fix here. The DS won't turn on. Green light flashes for a second.
"The DS won't turn on. Green light flashes for a second."에 답변Finally, after investigating this problem for a whole night, I’ve managed to get the box fixed. It turned out to be a problem of both screens’ back light circuits on the main board got burned. So no flash on any of them when turned on (symptoms: green light lit after turned on, brightens for 1 second, and turned off; can charge properly). You need to check all those LEDA1/2 LEDC1/2 connections on the main board all the way to the screen connectors. Refer to the following pictures. Make sure every color coded pins are connected to each other. If not, connect them with a cable from the pin next to the screen connector to the corresponding capacitor above start button. Something like this works for me!
"The DS won't turn on. Green light flashes for a second."에 답변OK. I have the exactly same problem. The thing is, I swapped both screen with another machine and all 4 are working fine. When the green light is on for the second, no screen flashes. Wifi module removed will make it stay green, but light green. Anyone ever got it fixed?
