    Im sort of in the honeymoon period with the 2000T where its new in my room and I want to love it.

    However its been dawning on me that I cant get BBC 1 HD and all the channels in that group like BBC2 HD and Channel 4 HD.

    I have tried getting the info about Winter Hill and the BBC B/PSB 3 group qouted as Channel 54 DVB 2

    I Have tried an automatic and a manual scan but it brings up no channels found on all possible settings.

    Has anyone had this problem please? Im at a loss who to contact. the roof aerial is amplified for flats but there is no problem with any other bands and the picture is superb.

    One thing that would make me return this unit is not being able to recieve all the HD channels. How do I investigate further?

    If you select Channel 54 DVB T2 using manual tune what do you get ? To make sure you have Winter Hill – what do you get on channel 50 DVB-T ?

    Do your neighbours get HD on channel 54 ?

    Hi

    Channel 54 DVB T2 gives no channels found. On channel 50 a load of channels are received in DVB T…… BBC 1 BBC 2 standard definition and 108 other radio and TV channels

    Good question about the neighbours but unfortunately its actually the sort of place where we keep ourselves to ourselves.

    This is a bit of a shame but I dont think I want to go knocking on doors to ask.

    I dont know whether I can get a BBC bod to measure whats being recieved at my socket. The niggle is if I dont know, I dont know if the Humax box is faulty

    Ah when I put it on manual search on channel 54 DVB T2

    Im getting 68% signal stength 100% quality for a few seconds than it drops out to zero. This flashes on and off

    That would appear to be the problem. Now I have to find out why. I have splitters and its a weird amplified aerial on the roof.

    I will try a direct qed aerial lead into the Humax only

    Ah Ive upped the signal strength to 73% by removing a splitter and the signal remains longer but its still dropping to zero…Hmmmm

    found the channels but the signal is too intermittent to keep the sound and picture up without hiccups. I get 73% then zero !

    Interesting as this could be the landlords aerial system. The landlord does damn all so I will have to investigate further and see If I can get a signal in my top floor of three floors with my own aerial

    This issue could be a local interference problem caused by a poorly screened HDMI cable and poorly screened aerial cables blanking a specific frequency. If you connect your TV using the box analogue output and remove the hdmi cable and you then get channel 54 you have the cause. Initially replace the aerial cable with a decent quality one (Ideally make your own with satellite grade WF100) and seperate the coax and HDMI leads as much as possible. Changing the hdmi cable may also help, strangely cheaper HDMI cable often work better thsan expensive ones in this situation.

    Thanks very much for your support.

    I will try as much as I can. Unfortunately its not possible to get at the landlords coax. The tv system went off completely about a year a go and im not sure he knows or cares what he is doing.

    Can you suggest a small home aerial which may just prove it can get 54 without this intermittent signal loss? Whats interesting is that its rapidly intermittent.

    Anything to do with DVB T2?

    Im using the HDMI cable Humax supplied and I probably think its not the Humax box and is poor wiring or short circuiting in the aerial system

    Not talking about the landlords wiring, just your coax that plugs into the wall socket. Is it the poor quality thin white coax ? Have you tried connecting your box to a TV scart socket and removing the hdmi cable ?

    To use a indoor aerial you would need to be close to a transmitter and on the right side of the building.

    Oh would you believe it!..it seems to have rectified itself tonight with all that group on a steady 74% signal strength.

    My Leads are QED Qunex TTV leads. Good quality ready soldered but bought used

    What is a bit dodgy if the wall socket alongside an FM outlet. Its getting a bit rickety and loose fitting in the coax socket. I think I will replace it.

    Please note however not one twitch on the other bands with a truly beautiful picture so whatever was hapenning was just on that PSB 3 band.

    This shows that the Humax is working but I hope it wasnt a glitch in the Humax Tuner….cant understand what I was experiencing since

    Just as I am typing this the picture dropped out for a second no signal so this isnt over yet

    The signal radiated by a HDMI cable can vary slightly in frequency. You need to do the analogue connection test. Have you moved the HDMI cable as far as possible away from the coax cable,

    Not yet but will do. Ive moved the HDMI cable away from the coax but still dont understand why it could only affect PSB 3

    Its been a long day. Picture is dropping out and messages come up to say it affected a recording on ITV HD. I see other people have reported that message comes up when recording is interupted so Im not alone in reception problems on freeview The drop out seems only once or twice per hour…Is this normal?

    I still wonder why that band only unless there are technical problems with perhaps too many competing channels. Is everyone else ok on PSB 3? BBC1 HD

    I will get to the bottom of it. It could possibly be a bad connection Ive yet to replace. Thanks again

    Channel 54 has a centre frequency of 738MHz. HDMI cables operate at similar frequencies. If it’s radiating at or close to 738MHz it will knock out the one mux and not affect the others. It’s a very common issue.

    You don’t by any chance have a wireless router or other RF kit like a cordless phone base station close to the box ?

    Oh I do yes I have a panasonic dect phone very near but the router has the wireless switched off.

    I will try everything

    I will be phoning the 4G people as we had a card through the door ages ago. Masts quite near and a mess of conflicting frequencies.

    I will get to the bottom of this

    PSB2 is nearer the 4G frequency than the problem frequency, and you have no issue with this. You need to look at your own kit. First step is move the dect phone to eliminate it.

    You still need to talk to your neighbours. May be one is using a illegal UHF re-transmission device.
