    If it's on an extension lead, connect directly for testing too. You get power loss over non active cables

    Or as i suggested try connecting the stick to a powered USB hub and that to the RPi.

    I would recommend the Official Raspberry Pi power supply, they provide a little more voltage which is helpful using DVB-T sticks.

    If possible use the "Official RPi power supply".
    Wiedehopt, it was indeed the power supply in the end, all sorted now, thanks for the original fix
