Jb38:
It appears to have completely inverted now.

Signal strength has dropped off to practically nothing. I can recieve 31 channels, all on 48 - and they are unwatchable.

Maybe hd disappearing was a symptom of a faulty booster and the it has packed in completely now?

Dsb: If what you have reported was the result of having carried out the test procedure referred to using the Panasonic then your problem could point to a defect in the line feed from the distribution amplifier used to feed a signal into your property, however in order to give advice appropriate to your situation could you please clarify on the following aspect of your installation that I am not quite clear about.

When you referred to a "communal aerial" and also one mounted in the loft, then are you residing in a property where other residents as well as yourself have a TV aerial socket supplied from a single communal roof aerial, but with you having also managed to fit an aerial in the loft by having access to it?

The other thing that I meant to mention about the test being, that is to connect the aerial directly into the Panasonic and use the TV simply as a monitor for the Panasonic.

Further advice dependant on reply.

The communal and loft aerial I mentioned are one and the same. It is shared with at least one other property.
I have no access to the loft where it resides.

The TV signal had dropped before I carried out your test.

I tried both the TV on its own and the Panasonic on its own. I also tried my sisters TV (not hd). None had a reasonable signal. I even tried a different cable from the wall socket with no change.

I contacted the council months ago and their policy is for two storey flats, it is up to the occupants and not them.

Dsb: Many thanks for the update on the situation, that said by yourself having completely clarified the issue, however now that it has been then if the distribution amplifier in the loft has failed then it would indeed result in the type of problem you are experiencing but though so should everyone else connected into the system, as the various outputs from the amp are fed by a common amplifier meaning that any defect in the amp affects everyone.

I feel your best policy is check with one of the other residents connected into the system to enquire if they are also experiencing similar problems, because if as would be expected they are then access will be required into the loft by one means or another, as it might even be found that the problem is being caused by the power to the distribution amp having accidentally been switched off.

Just purely to get an idea of the signal level being received you should try and borrow a set top aerial and carry out a retune using that instead of your normal aerial connection, if though you are unable to obtain one then just use a length of wire (about 6 - 8 feet or so) connected into the aerial socket of either your TV or the Panasonic, as I am only interested in whether or not anything is received irrespective of pixilation etc.

I am trying to update thread on the oxford transmitter page which you have been helping with but now in don't seem to see the latest posts I put on.

Is there a reason for this?

rob: I'm so sorry... I goofed up on an SQL query and all messages with no "Your site or @twitter" were being hidden.

Everything has been restored to "normal".

Thank you so much for flagging it up.
