I'm not saying the other fixes are wrong but mine did the same and my LED and Resistors were correct. Mine was the 9014 just below the LED, I missed the center pin.

Exactly same problems.

Hello, I had the same problem. The solution is: The resistors R7: 3k3 and R10: 33K were reversed. After putting the resistors in their right places, the device works perfectly. These resistors are at the left edge of the main board under the display. R7: 3k3: Orange Orange Black Brown Brown R10: 33k: Orange Orange Black Red Brown.

This GM328 kit seems to last a few mins after assemble.

i got mine and it does the exact same , returning it

Hell, the one they sent me wont even power on lol..

You can resolder the components or check your supply connections

mine worked well for a few months then switched it on one day and it switched its self off and dead as a dodo i check what i could holding the power button in the power gos past the regulator to the large ic but no led light ...not sure whats up !

Problem is in wrong LED diode polarization, try to solder it in reverse direction.

Hi, mine have the exactly same problem. What do you mean by saying 'wrong LED' ? Thank You :)

Hello Did you start working? My product did not work as well. However, I was able to fix it. There was a mistake in the parts included. Resistor 100 has been changed to 100k resistor.
