not is possible because if i unlock the screen, it turns off

Hello everyone, I have a problem with my box, yesterday while I changed the battery, the circuit of my box does not turn on any more, if I connect it to the PC via cable everything is fine and turns on, the circuit is DNA 75C, I checked all the welds and they're fine, a guy told me that it could be a component near the welds at the bottom that jumps and stops feeding the circuit, could someone help me? Sorry my english.
