Apenas aparece "ROKU" en pantalla, inmediatamente se apaga, y vuelve a encender, y así sigue en un ciclo que me aburre ya que no sé qué hacer para volverlo a disfrutar, porque antes funcionó perfectamente en más de un televisor.
You don't give the model number of your Roku device, so I'm going to assume it uses a USB cable for power. Make sure you're using the supplied power adapter (assuming it came with one) and not the TV's USB port. If you are not using the TV's USB port, try another USB power adapter from a phone or tablet and/or another USB cable.
