I'm sorry about the issue. What's the brand/model of your computer? Does it have windows xp, vista, or 7, or 8, 10? Or is it a mac computer?
When you turn on the computer, and plug it to the computer, does the computer make a sound (like previously)?
If you have a USB flash drive or a USB external hard drive, does it work on your computer?
If you have another computer, does it detect the camera when it's connected to it?
Please reply at the box below. Thank you,
