My warranty is already over. And i don't know how to troubleshoot the problem. So the controller is turn on when i press the power button long enough but it's turn off immediately after i remove my finger from the power button. It worked perfectly when i plugged in tho. Is it because the IC is already weaken or something's wrong with the battery ? I need an answer asap.
And btw sometimes it worked for 30 minutes with wireless mode. But it shutdown and I can't turned it on again. It's weird.
