Dsi power problem water damage
I spilt tea on my dsi xl about 12 weeks ago now. Finally got round to opening it up. The charger light was just flashing so I knew it was a power problem. started stripping it down when the battery power connector came off the motherboard (red and black wire connector) and when i looked at it closer it was corroded. I've cleaned down the corrosion that i can see on the motherboard with a soft toothbrush and it looks ok now. I also painstakingly soldered wires to the motherboard to fix that issue. Now charge light stays solid but blue light will blink once when I press the power button. The screens don't flash at all. I can upload picture of the damage I found If it would help. Could you suggest anything else as I can't afford to buy another one.
Thanks in advance
Don't have a pic of the power block from the battery broken off the board. just noticed a small black mark on the ribbon cable to the top screen too. I'm waiting for my isopropyl alcohol to arrive as its 1 fifth of the price on ebay than any shop here.
