I live in KT6 5EW and am having problems recently with signals from Multiplex COM7 Crystal Palace with picture pixelating and breaking up. This is happening on both my TV and Youview Box. The current signal strength is fluctuating between 0% and 75% with quality fluctuating between 0% and 65%.

BBC 1 both signal strength and quality 100%.

I have a very strong signal on the other muliplex broadcasts and has only been happening for about the last 3 weeks only on these channels.

My aerial is external and fairly recent.

I live in KT6 5EW and am having problems recently with all signals from Multiplex COM7 and 8 Crystal Palace with picture pixelating and breaking up. This is happening on both my TV and Youview Box. The current signal strength is fluctuating between 0% and 75% with quality fluctuating between 0% and 65%.

BBC 1 both signal strength and quality 100%.according to the Youview box.

I have no problems receiving London Live which is a lower powered transmitter. I tried a freeview retune on my YV box and now none of the Com7 & 8 channels are even showing. Prior to this I had no problems on any of these channels.

I have a very strong signal on the other muliplex broadcasts and has only been happening for about the last 3-4 weeks, only on these channels.

My aerial is external and fairly recent.

Any ideas ??

MikeB: Thanks for that, I've already done this. It is over 4 devices all of which were picking up the signals strongly with a splitter in the loft connecting to 2 devices downstairs and 2 upstairs so I checked all of these connections.
All were picking up these signals fine until about 3-4 weeks ago. I purchased a booster for the upstairs ones about 6 weeks ago as the signal started degrading slightly and now all have gone. I wondered if the transmitters/muxes were being downgraded as I note that ch 81 is moving today.

MikeB: Hi Mike well this morning everything back to normal with all signals returned so my guess is that the muxes were being prepared for the Channel 81 retune. Thanks for the help I was dreading having to go in to the loft and check everything.

MikeB: Hi Mike, I do hope not!! In answer to your comment no, but, all other channels apart from these were being received full strength and now these are too. The only reason that I tried the booster on the upstairs circuit was because there were two connectors to that which, as the aerial lead runs under the floorboards would not be easy to re-route. The aerial is not using a powered splitter, just a simple splitter box. Downstairs is direct and I started having problems on these last week on these channels which has now solved itself !!

Hi I've was trying to watch the local news on BBC1 HD (101) and it showed "not available in your area yet" very strange as all subsequent broadcasts were fine 30 mins later and SD BBC1 showed the programme BBC London news. I have just done a search on the EPG and all future showings of local news are showing " Please switch over to BBC One for the latest news from your area. Programming will resume on BBC One after the bulletin."

Have I missed something? Nothing is showing for maintenance Etc. I am on Crystal Palace with a great signal since Freeview installed new aerial. Am I alone ?
