The symbol shows the location of the Sutton Coldfield (Birmingham, England) transmitter which serves 1,870,000 homes. The bright green areas shown where the signal from this transmitter is strong, dark green areas are poorer signals. Those parts shown in yellow may have interference on the same frequency from other masts.

Are there any planned engineering works or unexpected transmitter faults on the Sutton Coldfield (Birmingham, England) mast?

I experience picture flicker on all channels on COM7. This occurs every few seconds and looks like when a traditional film ' jumps a sprocket '. There has been speculation that this is due to automatic switching between 1080i and 1080p - I locked my TV onto 1080i, rather than setting it to auto and this has cured the problem. However this problem was only ever experienced on COM7 - is someone experimenting on this multiplex only? My transmitter is Sutton Coldfield.

M Griffith:

COM7 is an HD multiplex and many TV sets are somewhat sensitive to the signal strength on such multiplexes. Can you please check what the signal strength reported by you TV set is on this multiplex. It should not be below 50% and not above 80%. Any strength less than 50% will cause the problems you report, as will any signal strength above about 80% (it does vary slightly dependent on make of TV). Having too much signal is well known to cause these type of problems. If that is the case for your reception, search this website for 'too much of a good thing' and take the advice to reduce the signal strength by fitting attenuators in the aerial lead at the back of the TV or removing any amplifiers you may have.

If you give us a full post code for where you live (or that of a very nearby shop or post office) we could examine the signal path and advise if there are any other possible causes.

Hi

I tried all signal strength investigations before posting my question, although the flicker that I am experiencing led me to believe that it was not related to signal strength. COM 7 is running at 75% strength. This multiplex is a lower power one from Sutton Coldfield ( around 90kw whereas the main multiplexes are 200kw ). Incidentally I experience no flicker on the other HD multiplex ( PSB 3 ) although the signal strength on this one is 100%!

The flicker doesn't involve freezing, pixilation or any of the commonly seen problems, which it why I described it as like a film jumping a sprocket every few seconds. Also, if it were a signal issue, I don't think that locking the TV onto 1080i would solve the problem as this is signal processing within the receiver. This is beyond the receiver front end, which is ( I think ) what is affected by signal strength / quality issues.

I have seen reports that Freeview is experimenting with switching between 1080i and 1080p, depending on the programme format / type and therefore my question was posted to see whether this is happening on the lesser used HD multiplex.

Michael Griffith: If its the TV, you can check easily what the TV is doing by bringing up the screen res - usually in the left hand corner of the TV screen, and should be something like 576/50hz, etc.

Have you tried varying the sources the TV uses? If the TV itself is auto-switching between screen res settings, you can normally switch that feature off and do them manually, but of course the source itself can also be varied. If you have a Blu Ray player, then that will of course output at 1080p as well, so try to see what combinations actually cause that 'picture jump'. If its on varying sources, is it the TV settings?

If not, then perhaps its a cabling problem. Narrowing it down takes some time, but its the only way.

Don't forget there could be the possibility of interference from any of the local 4G tranmitter(s) or in house RF devices, as is becoming a more frequent issue.
A 4G filter on the incoming terrestrial coax can fix the first item, moving your wireless router-modem and / or cordless phone / cellphone could be a fix for the other.

Please post a question, answer or commentIf you have Freeview reception problems before posting a question your must first do this Freeview reset procedure then see: Freeview reception has changed, Single frequency interference, and Freeview intermittent interference.

If you have no satellite signal, see Sky Digibox says 'No Signal' or 'Technical fault'

If you have other problems, please provide a full (not partial) postcode (or preferably enter it in box at the top right) and indicate where if aerial is on the roof, in the loft or elsewhere.
