I have a TSD smart charger, which seems to have stopped functioning correctly. After searching the web for what seemed like hours, I decided to just post a topic. Whenever I plug this thing into an outlet (battery or not) the LED blinks/flashes red-green-red-green then shuts off. No matter how long I wait, it doesn't do anything but get warm (short circuited?) Should I disassemble the thing? Please help, I really don't wanna spend another $25-35 for a new charger. Other info: Charging battery: 8.4V 1200mAh on the 0.9 setting.
