I have an original tivo box. I am experiencing significant picture distortion on all channels. Audio is fine. I have tried different HDMI ports and HDMI cables but still the same. I have reset the box numerous times with no effect and carried out a self text on 150 which identified an issue and reset the service. However this didn't resolve the issue. There are no known TV issues in the area. The TV is not old either and I've tried another TV too.
