You can try these simple way to troubleshoot:
1. Make sure you're entering the correct 24-word password on the new device
2. Ensure that both your ledger live and ledger firmware are up to date. An outdated version might cause issues with recognizing the device
3. Disconnect and restart both you ledger live and device then reconnect your hardware
4. Since you mentioned the device is showing 0.00 on the new computer, try using the device on the original computer where the funds were recognized. Sometimes this can resolve issues if the new setup is not properly synced.
5. If you're using passphrase, make sure you entered it correctly when restoring your ledger

If these don't resolve, they could be a deeper issue with your device or setup.
