The LED light is not a power indicator, but a communication indicator.
Please first press down the H/P button to make it in the H position.

1. Please test whether the resistances of 5V point and 3.3V point to ground are short-circuited.
2. If so, remove D1 and L29, and test whether the resistances of 5V point and 3.3V point to ground are not short-circuited. And then test whether the resistance between the two ends of C29 is short-circuited.
3. If so, the chip U2 should be fault. The model of U2 is CY7C68013A-100AXC. You can try to purchase it on eBay.

5v and 3,3v are ok.the resistance between the two ends of C29 is 318 ohm. Author: amy Time: 2021-8-31 09:04
Please test whether there is a short circuit between any two of these four pins.

there is not a short circuit between any two of these four pins''(There are some resistance values between 920 ohms and even higher ohm value'') ..I hope that with your help we will find a solution.thanks Author: amy Time: 2021-9-2 11:48
Please change the USB cable or computer to try.
If the problem still cannot be solved, please contact the seller to repair it. Author: kutsal33 Time: 2021-9-12 12:11
