my Humax Freesat PVR has lost picture on Channel 216 (GBNews) only, just on the live content. The adverts appear as normal. The sound is not affected. All other channels work perfectly, including recording and playback. Have tried unplug/restart with no improvement. I live in the Republic of Ireland, but the satellite reception has been excellent for the last 12 years except in occasional heavy rain downpours. Any advice would be welcome!
