My problem started after putting the battery in backwards (positive pole with the negative). I had the console disassembled because I was trying to fix another problem and accidentally put the battery in the wrong polarity and then it wouldn't turn on. I have already tested the two fuses that I found in the mainboard, the one next to the charging port and the other next to battery contacts (I don't know if there are more than two) and they both have continuity.
The console charges the battery, because when I connect it, the charging indicator LED turns on. When I disconnect the charger, the charging LED stays on until I remove the battery. When I try to turn on the console, it doesn't give any sign of life, not even LED indicators. I would like to know if there is way to approach the problem or because I don't want to mess it up even more. I have also tried cleaning the connectors.
