nRF7002-dk not powering by the USB

[ramkumarkoppu]

I purchased nRF7002-DK in May and after using it for 2 months only powered by the board usb connectio on its debug port, a week ago it stopped powering on, is it possible to fix this? 
If I connect usb cable to the nRF5340 port then I see some of the LEDs on the board.

Hi,

Here's some troubleshooting steps you can try:

• Have any of the current measurement jumpers been removed from P22 or P23?
• Have SW6 or SW10 been changed from the default? SW6 is set to REG and SW10 to DEFAULT.
• Can you measure the 5V and VDD pins? Is there any voltage on these nets?
• The power switch can wear out if used a lot. If this is the case it may require a little more force to make the connection. Can you try holding the switch in the ON position?
• If there have been any force applied to the debug USB connector there may be a poor connection. Can you try applying a little bit of force up/down on the USB connector while plugged in?

 

Best regards,
