Since being asked to retune sometime last week, we've lost (I think) two complete muxes. E4 and Dave have gone, we're getting no signal messages. We've had problem free reception for 3 years. What confuses me is that the same thing has happened in my place of work, and also friends saying they've lost the same channels. CF5 postcode / Wenvoe TX

Simon Jones: Please do a "first time installation" or do this - My Freeview box has no EPG, is blank on FIVE, ITV3, ITV4, ITV2+1, has no sound or the channel line up is wrong | ukfree.tv - independent free digital TV advice .

RonP: Yes, the services are being broadcast as per the table at the top of the page. Please see Single frequency interference | ukfree.tv - independent free digital TV advice .

Thanks for your suggestion Briantist, and please accept my apologies for forgetting to mention that I've carried out numerous first time installs, with cable removed in between.
I'm getting perfect reception on PSB1, PSB2 & COM6. Just getting constant no signal on all channels on COM4 and COM5.
The missing channels appear on the correct channel numbers, and strangely, I think the EPG works, but just nothing except no signal.
I can't see why it would be a power issue, as COM6 works perfectly, and according to the chart above, it's on the same power.
I've also tried a different freeview receiver to rule out any TV firmware issues, (it's only 3 years old though).
A visual check of the aerial (digital one installed three years ago) couldn't find anything.
No new electrical items (e.g. games consoles, PCs) have been added.

Simon Jones: I would check Single frequency interference | ukfree.tv - independent free digital TV advice - also check you don't have too much signal. If you have boosters or amplifiers, try removing them from your system.

We are having problems with channels e.g. Quest,Dave & many more We are having no signal for these. So far no explenation has been given for the loss of these programs other than the fault always lies with the house holder. The system has been checked and no fault has been found so the problem must lie with the transmission itself ( Wenvoe ).

Donald Chamberlain: The responsibility for reception is indeed yours. Please see Single frequency interference | ukfree.tv - independent free digital TV advice for help.
