published on UK Free TV

The problem could be one of:

- the aerial has been moved or damaged;

- the cables or connectors that connect the digibox to the aerial are damaged;

- the digibox has broken.

If you have a "spare" digibox you use this to test the aerial connection. Can you still watch analogue TV OK?

Hi - seems that CM15 (Brentwood Essex) has lost most of the freeview channels this weekend - does anyone have any information on this or are experiencing the same problem?

Hi There,

I hope someone may be able to help me. I have trawled through all the various other posts on this fine website but I can't find a solution. I have:

Samsung LCD TV with built in Freeview tuner
Panasonic DMR-BWT700 Blu-Ray with built in Freeview twin tuner
Aerial on the roof
Heathfield (West Sussex) transmitter - not yet switched over

Up until January of this year, I had the aerial coming straight in from the wall socket into my Samsung TV and was able to pick up all Freeview channels. I then purchased the Panasonic so I would be able to record Freeview channels. I installed by connecting the RF cable from the wall socket into the Panasonic and then out the Panasonic into the TV. I scanned for channels and was successful in picking them all up. Occassionally I would lose a couple for a short period of time but they would always come back.

About 6 weeks ago (from doing nothing different) I lost most of the channels. I retuned and was only able to pick up the multiplex 2 channels (ITV, C4, C5 etc). I tried reverting to factory setting before retuning but this had no effect. I have tried retuing every few days but am not able to pick up any more channels.

The crazy thing is, I still have the cables going from the wall to the TV via the Panasonic and am able to pick up all the channels still on the TV, however if I switch the Panasonic on, it then affects the TV reception, causes it to freeze.

Is this a known problem of the Panasonic or could this be connected with the upcoming switchover? I had put it down to Inversion when it first happened but that high pressure of early March has well and truly gone now!

Hopefully, that has covered everything but if you need more info, please let me know. Any help would be most appreciated by this frustrated viewer!

Many Thanks,

OK, so within an hour of posting my problem on here, I think I have found a solution via someone's comments on a review of the product on Amazon! It seems that if the aerial cable is near or touching the HDMI cable, this alone can cause loss of channels. I've rearranged my cables, retuned and hey presto, I now have a full compliment of channels.

markyb: Cables can interfere with one another when in close proximity. The lower the level of signal the greater chance that any interference will have a negative impact on reception.

So come switchover when the signal levels from Heathfield are higher, you may find that such interference does not result in loss or poor TV reception.

I have a USB dongle TV tuner and I know that if the RF aerial cable is put next to the USB lead then it causes problems with reception. that is, the signal carried along the USB lead interferes with that in the RF lead.

My samsung LED tvs seem to have lost the freeview signals and now my LCD Samsung seems to now be waning in quality. My Bush LED freeview seems to be OK - that tv is only a 20", the samsungs are 32" and 1 at 42". They are all on the same aerial with a booster - in the loft. Surely I am not that unlucky that all my samsungs built in freeviews have broken. Any ideas or heard of samsung tv problems??

I'm down to about 30 channels after the latest Freeview retune. Everything was fine before and now I'm missing channels including Fimlm and ITV4, most commercial radio stations missing as well.

I have various digital appliances but recently, last two days, I seem to be have trouble with freeview. If I plug in a cheap freeview box the piture is fine and receiving all channels. I f I unplug it then I lose all signals from the other tv's in the house - some integrated with freeview others with a box i.e. humax or a dvd recorder LG. Any ideas? As long as I leave this small cheap freeview box plugged in and on all systems work fine.
