About 3 weeks ago i had a new aerial fitted and 4 tv's wired into it using a booster box to carry the signal to all 4. the tv in the main room has built in Freeview, but we mainly watch Sky on this set. The other 3 tvs all have freeview boxes attached. Everything has been running great until tonight. All 4 tvs have suddenly developed really bad analogue reception, so bad that the channels are unwatchable due to the visual interference. And therefore, the freeview reception has deteriorated so that it to is unwatchable, previously freeview was finding 101 channels, i have done a retune on all the freeview boxes and now i am only finding 68 channels! and they are still unwatchable. the weather today has been really bad, overcast and violent rainstorms. but i cannt see that it should effect the analogue transmission.. I am picking up the signal from Winter Hill and have never had any problems before. Could this have anything to do with the switch over date of 4/11/09 for my area, are they downing the analogue signal slowly building up to the change over. This all seems really strange. I have looked at my aerial and it doesnt appear to have moved at all. There is no issues with Sky that is still transmitting on the main tv.

Help!! Any ideas?

Has the "Booster box" lost power. It is either fed from a remote power unit along side one of the TV's or directly plugged into the mains.
Most distribution boxes have a LED showing that power is attached, hopefully yours is not fitted up on the mast, if so call your aerial fitter back.

There's no current engineering work at Winter Hill, according to this website - Freeview on Winter Hill TV transmitter | ukfree.tv - independent digital TV + switchover advice, since 2002 Could the problem be due to your amplifier being on the blink? Incidentally, analogue switch off date for you is 2 December, not 4 November, and your digital signal strength shoulld then be increased ten-fold, so your amplifier may then need to be turned down.

Hi. My booster box is by the main tv and the red led light is on, so that appears to be working. (It shouldnt be glowing green, should it)?

[jomax1]

Amplifier? Whats that? I had a complete new system installed, aerial, co-axial cables, booster etc.

The switch over date for my area is definately 4th Nov

My "amplifier" is your "booster". Unfortunately, it sounds as though a fault may have developed somewhere in your new set-up, possibly due to the heavy rain.

Phase 1 of Digital Switch Over for Winter Hill is 4 November; but Stage 2, when analogue is actually switched off, is 2 December. As far as I can make out from the link in my previous post, nothing much will happen in your area until the latter date, when all the analogue channels will be switched off; the Freeview muxes change channels; and Freeview power increases from 10k Watts to 100k.

The box with the red light on, if it has 1 mains lead and two other cables, i.e. one in and one to the TV then it is a power unit that is supplying power to a unit either in your loft or up on the aerial stack.

I have exactly the same problem jomax, although not a new system. Digital switchover went fine, new channels setup fine.

On Tuesday 6 Oct between 3 and 3:30pm everything vanished.

I've put the aerial directly into the two tvs, just coloured snow on BBC1, I can make out a programme behind it and hear it well enough. The other analogue channels are just snow really.

Digital - nothing whatsoever.

Yet at 3am this morning I still had the tv on while copying from hard drive on the dvd recorder to a disc, and everything came back perfectly. Analogue and digital. For two minutes. From then until 05:43 everything came on for a couple of minutes then went off for half an hour or varying intervals.

I'm on the Emley Moor transmitter. I have a booster. The green light is lit on it.

I've just found this. It doesn't have a date on the page, I presume it's current. But "weak signal" isn't "No signal", is it!? I did wonder about work being carried out when everything burst into life at 3am precisely.
