Hi @coronet,

What is the model number of the TV?

Can you view the TV's menu screens OK?

Does the TV respond to the remote control, if there is one and/or the TV control buttons?

What have you tried to do to get a picture with audio e.g. different inputs e.g. RF, HDMI, different cable connections etc?

完成的
