rob: Some brands of Freeview receivers are more prone than others as far as reacting in an adverse way to any forms of localised interference that may happen to be around, and especially if the source of the interference is located nearby such as possibly from something sited on the other side of a properties separation wall, this being my reason for suggesting that if at all feasible to try the Sony TV up in your daughters bedroom, as you really do have to eliminate the possibility that the problem is associated with where the TV is presently located.
You could of course try your daughters TV on the aerial connection used by the Sony and see how it performs, but as aforementioned, interference affects some TV's more than others when operating "close" to a source of interference and so the test is more valid if the Sony is tested out using daughters aerial outlet point.
If though the problem still occurs then that could suggest that its down to a fault in the TV's tuner, because if the signal level received was totally over the top then its unlikely that your daughters TV would not be affected in some adverse way.
Another point I was wondering about being, as you are not using any form of powered splitter then what arrangement are you using to feed the aerial into the two outlet points?
Another test that I would like you to try is to carry out a signal strength / quality check on your daughters TV whist its on BBC1and making a note of the indications seen, then carrying out a similar check on the ITV1 channel followed by comparing that seen with the indications obtained from the BBC1 mux.
If for any reason the signal cannot be checked in this way on your daughters TV then go into the TV's tuning menu and select "manual tune" and entering C53 (BBC) into the channel box but with this action NOT being followed by pressing search or scan, as on most devices the level that the signal is being received at will appear in the strength / quality bars, on completion of the BBC1 indications carry out a similar check on the ITV1 mux by entering C60 into the box and giving an update on results.

rob : Thanks for the update! I would also appreciate if you could let me have the model number of the Sony in question as I would like to check out the service manual for the set, this being something I should really have requested before now.

Hi JB,
The TV model number is KDL37w5500, was working fine as i say up until a couple of weeks before xmas. Also there seems to be a lot of masts in kidlington and there is a tetra one close to me probably within 1/2 a mile but the interference is intermitant not all the time.
Cheers again JB for your help so far. just another question, am i right in saying that if it were the cabling then all channels would be effected not just channel 60?
Regards
Rob

Not sure but i might have found the problem but still not sure, i split the Ariel in the loft and then had to split again down stairs from the main point on the wall under the floor to a splitter to 2 points.
plugged the Sony into the main point before it goes below the floor and things seem ok, there must be something going on under the floor, however we have had solid wooden flooring fitted now and i cannot get to the splitter to check. Think i will try running a cable from the main point above ground to the Sony in its normal position. Also the cable under the ground is single screen so if interference is present then that might not help.
plugged daughters tv in to Sony point and the signal strength said 0 on 53 but strangely the quality was 99 however it would not pick anything up on 60. Also i noticed it said modulation unknown, when plugged in the main point it picks this up and gives 100% quality with 64% strength and shows the region under modulation.
hope this is right will try cable above ground even though that will look really bad running along the skirting board.

Made a fly lead but still seems to happening when Sony tv is back in its normal place. Move to other end of room on the same fly lead and that seems ok. moved Sony to about 10 inches from the wall from and put the original Ariel back in that, still blipping but maybe not as much. Now i am really confused if its something on the other side of the wall or not.

C60 channels improved, however not perfect still the odd glitch at the moment, back to my original set up, just moved the tv a little for adjoining wall, do not really know if it is that which has made the improvement or not. To get rid of the glitches can i get some kind of filter?
still cannot work out why daughters tv seemed to suggest there was no signal on the Sony Ariel point. Also the strength of the signal is high on all channels on the Sony, but suggested 64% and i could not even get the channel 60 channels at all.
still confused.
