New TV tuning issues
Thought I'd throw this one out to the general DS readership.
My father's having issues with new Freeview TV's and I wondered if anyone had any suggestions. He purchased a Sony TV from the local Tescos a couple of days ago, got it home and set it up all okay, but when he turned it on the following morning it apparently had "lost" all the free and was asking to retune again as if it was a new set-up, and apparently did this a couple of times, so he got frustrated and returned it to the store yesterday. He swapped it for a Samsung model (Joiii model UE40K5100) and again tuned it all in and all okay, but when he turned it off and on again, no channels so had to retune. Turned on this morning and the channels were still there, went out and when they came back and turned it on they'd gone again (??). Retuned at 11.30 this morning, and as of them returning from a Sunday Lunch out it was all still okay, but he's obviously worried in case it happens again. Unfortunately I don't have Freeview as up where we live (the second highest village in England) TV aerials don't tend to last long, so can't really advise him as to what might be wrong. It does seem strange to me that this is two different TV's that he's had the same issue with, so I wondered if there's something obvious he might be doing wrong (would turning the TV off at the mains cause it to "forget" it's been tuned in previously, for example). Any help gratefully received, and will be passed on

Maybe a variable signal, which could be being "detected" by any tv or other freeview device connected to that aerial. The variation in signal may mean channels vanishing and re appearing and the equipment can spot this and trigger auto or prompt for re-scans, giving different ch line ups each time.
A variable signal could be down to- The weather. (Recent weather in the s.west lead to us loosing most of our freeview chs for several mins, then repeated a few hours later. Sometimes, the stronger chs hold on a bit longer. Note the weather effects can stop even a powerful freeview signal such as ours). Engineering work at the transmitter mast which the aerial is pointing to. (Output power is turned down or off for periods of time while working is being done, may only affect certain but sometimes all of them). Poor signal due to insufficient gain at the aerial (aerial too small for ambient signal at that location). Try a bigger aerial, maybe try adding a signal amplifier. Poor or intermittent signal on some chs due to incompatible aerial. (Recent introduction of 4g mobile meant a shifting round of freeview frequencies for some parts the uk, some people may need a new group T aerial). Intermittent service due to interefernece (4g is the most modern, you can pick up a simple plug in filter for about £10 in most hardware or DIY stores and electrical stores. Poor or intermittent or variable signal due to a bad connection, bad aerial cord, in the aerial wiring. (Try moving the aerial cords about a bit, esp where the cord enters a plug - they can become wobbly over time, + make sure no aerial cord touches an HDMI cord as that can lead to interference. If the sound and pic bounces all over the place and then settles when holding one of the aerial wires at a certain angle, then either remake the affected aerial or buy a replacement cord). |

Disconnecting the aerial overnight or turning off an aerial amplifier is likely to cause some TVs to drop programmes, all in this case, from the EPG. Problem occurs if the TV is in standby but finds no signal when it does a re-tune in the small hours of the morning.

Try turning off 'auto update' - I've got a Panasonic set which did something similar i.e. wanting to be re-tuned every couple of days - that fixed it.

Is he 'saving' the tuned channels?

What you say is correct but the fact it has happened on two sets points to something other than the TVs themselves. I have three Sony sets, all auto update overnight without any problems. My Panasonic PVR puts up a caption advising a re-tune when it detects new services which can be a bit annoying but as you say you can turn that off if you wish.
Whether it's related to a transmitter glitch, an aerial glitch is kind of academic. What would be interesting to know is what the OP's father had before and whether that experienced any such issues. |

Not necessarily - if both have 'auto update' activated then that's what they'll do.

Thanks for all the suggestions. They've all been passed on and we'll see if that makes any difference.
In reply to AlanO, his previous TV was indeed an old 32 inch Sony model which only picked up basic freeview channels (I.E. no HD channels) so he decided they needed a bigger updated set with better sound and HD to watch some guy called Attenborough and his planet earth sequel. |
