My stock unmodified DS (original) just suddenly died. This was an older DS, I believe it has firmware firmware 2 or 3. I was just playing MP:H (from the actual card) and all of a sudden the system speakers gave a loud pop, and the screens faded away (like what would happen if you took the battery out while playing). I had a brand new official rumble pack in slot 2. While trying to figure out what is wrong with my system, the first thing I did was to discover the symptoms. I removed the card and cartridge from slots one and two. Basically the system was completely non-responsive. The only responses i can get from the system is a "pop" from the speakers when I push the power button. Also plugging in the wall charger turns on the orange charging LED. When finished charging the orange LED turns off. In stock condition, I am unable to get any other responses from the system. Since the system is long out of warranty, the next thing I did was open the system. I found that both fuses (F1 and F2) appear to be intact (according to my multimeter). Further I noticed that if the top half of the system was unplugged (ribbon cable removed) I could get the system to respond a bit more. In this case, if I push the power button the green LED comes on. It stays on until either I release the button, or ~2 seconds have passed, whichever comes first. If I plug that cable back in, once again the only response to the power button is the speakers popping. Does anybody have additional insight into what is wrong? I would like to repair my system if it is possible, rather than paying to buy a new system. The way the system is responding appears to rule out a battery problem, and I have checked the fuses. No components appeared physically damaged, and so I'm a bit confused. What is wrong with the system? I'm also wandering what caused the problem in the first place. The only thing I can think of is the possibility that the rumble pack was defective and damaged my system, but for the few hours prior to this that i had used it, it seemed to be fine. Any ideas?
