@marianoale, if you're not into troubleshooting these things, consider going the refund / replacement route.
You'll need a multimeter to start troubleshooting. If there is zero sign of life, check the power pins first, VBUS (see if USB power is getting through, past the USB-C socket) and 3V3 (output from the LDO regulator, which will power the RP2040). Once we have an idea of the power situation, then we can test other things.
Then again, it may not be a very good use of your time (and the board may still be dead at the end of the day), so you need to weigh your options. Getting an authentic Pico board from a reseller would be the lowest-risk option. Buying boards from sellers trading cheap electronics parts is not without some risk; sometimes we get bitten, then we adjust our purchasing strategy going forward.
