Over the last month or so, I've been getting increased disruption on some Freeview channels (such as 5 USA) when viewed or recorded later in the evening. I'm still trying to pin down the symptoms, and as a first step I replaced my aerial booster last week with a new one (Labgear LDA204LR), the old one being over 25 years old (my aerial is internal and serves three TVs including the one connected to my PVR, running CF 3.10). And a new problem has emerged, although I can't be sure it wasn't present before I changed boosters ...
I can no longer view Freeview Mux 27 channels (ITV, etc) on a TV (Samsung UE40JU6400) connected to the PVR's pass-through. I've retuned the TV twice. On the first retune, it did not even pick up Mux 27. On the second retune, it picked up Mux 27 but with Signal Quality reported (by the TV) as 0-15% (with Signal Strength 90%).
Nevertheless,
I've recorded the Signal Strength / Signal Quality for each of those setups (all using the booster), and they are as follows for Muxs 21, 22, 24, 25, 27 and 28 (all "percentages"):
TV 1 (via PVR pass-thru) .. 94/70-80 .... 92/25-50 .... 94/100 ....... 90/40-60..... 90/0-15 ...... 90/50-80
TV 1 (aerial cable) ............... 91/100 ........ 80/100 ........ 90/100 ....... 82/100 ......... 89/100 ........ 90/100
PVR (aerial cable) ............... 51/100 ........ 47/100 ........ 48/100 ....... 47/100 ......... 45/100 ........ 47/100
TV 2 (aerial cable) ............... 92/100 ........ 93/100 ........ 96/100 ........ 93/100 ........ 93/100 ........ 93/100
TV 3 (aerial cable) ............... 95/100 ........ 92/100 ........ 94/100 ........ 91/100 ........ 92/100 ........ 93/100
I assume the reported difference in Signal Strength between the PVR and the TVs is just down to a difference between those devices of what is considered to be maximum signal strength.
Any ideas on how the Signal Quality of one specific Mux could be affected in this manner?

Nevertheless,
- I can view all Muxs but 27 (i.e. 21,22,24,25,28) on the TV (when connected to the pass-through
- I can view ALL Muxs on that TV via the PVR (i.e. when connected to the HDMI)
- I can view ALL Muxs on that TV when directly connected by cable to the booster
- And I can view ALL Muxs on 2 other TVs connected by cable to the same booster
