[HDR1000S 2TB. Quad LNB] This has been working OK for years. Signal strength etc is all reported normal
When on Sky News I get low or no signal. All other channels seem OK. However, if I go to another channel and start recording (now, not future record) then go back to Sky News it works. The recording did take place at the same time.
If I then stop the recording by going to recordings, Sky News remains working. Turn the box off/on and Sky News is gone.
I have swapped all cables and LNB sockets to no avail. I have a second smaller Humax box with single feed and no recorder. It works fine on Sky News. My cable/socket swaps included connecting this socket to the [faulty?] other box.
It sounds to me that one tuner may be faulty on one tuning (possible?) and that starting a recording perhaps switches which LNB input is used for record, or maybe one LNB is always used for record but only switches when a recording starts (is this possible even?)
[EDIT] That is misleading, neither LNB input will work independently, only for Sky News.
Any advice would be great. Thank you for reading.
