Hi looking at the new updated map for coverage from Darvel , the area in light green which states can have interference from "other" transmitters , is this the interference which i stated was happening ie; Com muxes 23,26,29,transmitting and overlapping and affecting some of my customers on the west coast of Scotland and incidentally is this interference the same way in reverse during certain dry sunny [ high pressure ] weather conditions ?? P.S. please email me direct as i find threads and posts hard to find on this.

Setting up a new HD TV (LG 42UB820V). Locatted in Kilchattan Bay Bute. Always used Darvel good reception and no problems on old TV.
New TV fine for all except HD channels. On set up finds all the HD channels but puts then in channel 800 and upwards (I thought they should be from 100 upwards). When I try to view says no signal.

Any suggestions greately appreciated as unable to find any help on LG website and question on FREEView chat got nowhere!.

Thanks
Tom

Tom Cromack: When that sort of thing happens its usually because duplicate channels have been received, the question being are there anything stored in the EPG 100 ranges? if not, then you should carry out a "manual" scan on Darvels HD Mux C28 / 530.0Mhz and see if this populates the EPG100 range.

Should it not do, then your best policy would be to reset the TV by using "first time installation" or some similar sounding term, as that will wipe everything stored in the tuner including any possible glitches that may have occurred during your initial set up procedure.

As a matter of interest, were you able to receive HD channels on your old TV? the reason for mentioning this being that a rather large line of sight blockage exists between Darvel and your location, (as seen on the undermentioned link) and HD reception is more critical over that of SD as far as the quality of the signal being affected is concerned, something which could be a factor in HD reception problems.

You should also try a signal test on Mux C28, the procedure being to pause after entering C28 into the manual tune box, as on most sets if anything is being received the strength / quality of will be indicated on the signal bars.

By the way, the other COM7 HD transmissions are on Mux C31 / 554.0Mhz

Unfortunately I cannot be more precise as I do not as yet have the manual for your particular model, and LG does not appear to have added it to their download site.

Thanks jb38:
Previous tv did not have HD facility, reason for change.
Have done auto and manual updates after factory reset. Until this morning all put HD channels in 800's.
The manual update shows signal strength of all frequencies where downloads occur at 90% +

Strange thing happened this morning switched off with channel list as above. Came back at lunchtime and found all the HD channels in 100+ range .

Will leave as it is and see what happens.

Many thanks for your suggestions.

Tom Cromack: Thanks for the update, albeit that what you have reported is certainly a bit strange, although it all depends on exactly what's meant by switching off, because if this involved completely switching the TV off, i.e: "not" in standby, then this is the procedure commonly used in most digital equipment to rectify some problem that has occurred in the system, e.g: like rebooting a PC, but though, if you only meant leaving the set in standby then the reason for the situation having apparently rectified itself really is puzzling.

Of course the main thing is that your HD channels are now located in the correct order, and that's all that really matters.

Over the last few nights (since Saturday 7 Feb 2015) the freeview signal has been intermittent, with picture and sound failing often several times per minute and the message "no signal" displayed. Our aerial is directed to the Darvel transmitter, but our neighbour is having a similar problem form the Lochwinnoch transmitter.

Ken Johnson: Lochwinnoch receives its signal over the air from Darvel. Elsewhere there is a complaint from someone who receives from Arrochar which gets its signal from Ardentinny which gets its signal from Darvel.

Arrochar (West Dunbartonshire, Scotland) Freeview Light transmitter

Maybe this is something with the transmitter.
