I'm sorry about the issue. What's the model of your device?
Is there any power / light?
When you turn off, what happens?
When you turn on, what happens? Does it show anything?
Please reply at the box below. Thank you,
Please try this first: Press and hold the Power on / off button on the device for about 30 seconds, then turn it back on and check.
- If that does not work, please answer my questions in my previous reply above, so I can troubleshoot the issue further.
