You can still try a different USB cable even if at first everything seems to be ok with the one you are using. Maybe it's losing power somehow and doesn't have enough juice to power on the display.
If it's not that, I guess your Trezor's screen died or is dying on you. A Ledger Nano S screen is easy to replace but I don't think you will have much luck with the Trezor One.
There is a trick you can try with your phone camera. Connect the Trezor and fire up Trezor Suite where it asks to enter the PIN. Then, turn on the camera on your phone and point it at the screen of your Trezor. Look at the image on your phone's display and check if you can see the PIN pattern. Adjust the angles. Try both with the front and back camera of your phone. Experiment with different lights in your room. More brightness, less brightness, etc. Maybe it will work.
Some say you can also try pointing a flashlight at the display or turn on the flash on your phone.
I would also contact Trezor support and tell them what is happening. Ask them for advice.
Did you maybe drop the device on the floor? Can humidity be a reason the Trezor is dying?
Tried everything you said, still no chance. Thanks.
I only barely use this hardware wallet, maybe that is also the reason, like for long time, it's not plugged in.
Contact Trezor customer care instead. This is the best that you can do.
It may get to the point that you will have to get another Trezor hardware wallet, this will be a good option.
Warning: make sure that you did not take it to anywhere for repair, your wallet is different from your smart phone. If Trezor did not tell you to send it to them for repair, do not give anyone else for repair, but just buy a new one. Luckily, there is still Trezor one on the official Trezor website but I will advice you to get something like Safe 3.
Thanks, I'll try to contact them.
Saw one of the comments, I think it's not worth fixing anymore.
Is there any way I can see if there's any more funds inside my Trezor? I remember, I already transferred out all of my funds from this hardware wallet, but I just want to be sure.
Like there's a way without buying again a Trezor Model One?
