So my old trezor stopped working. (The web wallet asks me for the pin but screen is blank )
are you own 24 recovery seed?. if yes, do import the recovery word into another wallet like Mycelium, Electrum or Coinomi wallet.
This is a very risky suggestion especially to a newbie that can't guarantee whether it's laptop/computer is infected with virus and malware. There are viruses and malware running 24/7 with the sole purpose of searching and finding sequences of 12,18 or 24 words. Hardware wallets are invented for this exact same reason. So if OP decided to enter his 24 recovery seed to a software wallet then his upcoming new hardware wallet might be worthless and not risk free if ever there's really a virus on his laptop/pc.
