We switched to Freeview when our old TV died. We have a flatscreen (Panasonic) on Freeview and it didn't take too long before I had to switch our VCR for a recorder / blueray (also Panasonic) with two Freeview tuners. The aerial is split between the TV and recorder so it's not greatly weakened like it was when they were on one cable.
Apart from some interference when it rains (we're in a hilly suburb sheltered from the nearest main broadcaster, it works well. I've just checked and today the TV is signal strength 8/10 - and the quality is 10/10. The recorder is the same - although signal strength is 7/10 on some channels. Interestingly the ones that are dow slightly are not the onces that were weak - I assume the result of retuning last year.
So that's our scenario. The problem is that over the last 3-4 weeks we've been having problems with the recorder. My first thought was the machine itself was playing up. But we had the aerial people out - and they found that there was indeed a minor problem to do with the old cable connecting to the new boxes. So they left - and the same problem returned. So they came back and replaced the cable from the aerial to inside the house. And they left - and the problem returned. That was Monday.
Last night it worked fine. When we finished watching what we had recorded, we went to switch off - and noticed that the recorder was showing corrupt pictures - on all channels.
Today the aerial people told us what we'd already concluded - it is almost certainly interference. They added that most interference problems are caused by microwaves (ours might be used at dinner time - but now when we're recording), cordless phones (ours doesn't get used much - and definitely wasn't last night) and wifi.
Now ironically our laptops were being used last night - when the programmes were being recorded - but not when we noticed the recorder was displaying corrupt images. We're not ruling it out - but it does seem unlikely. The faulty image occurs both when we're out and when we're watching another channel at the time of recording.
So does anyone have any tips that might lead us to a better outcome - or can they point us to someone who might solve the problem? Thanks
