Purchased from the official shop in October 2022. It was working fine until just recently, but now it won't turn on. It seems like there's a problem with the battery, but the cause is unknown. When I connect the power cable, the red light blinks slowly, indicating it's charging. However, it never shows that charging is complete. When I unplug the cable and try to turn it on, the red light just blinks rapidly, and it still doesn't turn on. I've tried holding down the power button, and also tried holding down the trigger and record buttons simultaneously, but nothing has improved. The exterior has some scratches and minor wear from normal use, but there's no major damage like dents, and it's generally in good condition. The accessories are all shown in the photos. Please consider the above condition and understand that this is a junk item before purchasing.
