I switched from a broken 4000T to the 5000T a few weeks back.
I was immediately suffering from poor signals on several channels, especially HD ones. Picture stutter, channel not available or encrypted. Recordings on a stuttery channel don't show the symptoms. The severity can vary from time to time.
Last night the stutter was on most channels I checked across different MUX's, a handful such as Made In Birmingham seemed OK.
Humax suppport advised a manual retune which made no difference.
When checking the signal quality I see 100% for the signal and quality on Tuner 1 but Tuner 2,3 always show zero - is that a normal state of affairs?
Nothing obviously changed in terms of the aerial/cable and since the aerial is chimney mounted, I can't fiddle with that myself. Is it worth getting a basic signal meter from Argos etc ? or are they fairly useless for diagnostics?
Or does it point to a defective box?
