TERRESTRIAL RECEPTION PROB ON RTE2/TV3 ON ONE OF THREE TV'S?

Widescreen

Hi Folks. I would appreciate if anyone could look at my post below in relation to my terrestrial reception lately.

My main lounge set up is Panny Plasma tv, 2 sky boxes and dvdr. I have my terrestrial aerial coming in through my main sky box and so on. I also feed 2 other tvs from a dist amp behind the tv on the wall. The terrestrial signal on all tv's was perfect on all channels, then last week, suddenly without anyone touching anything, Rte 2 went very snowy and unwatchable and tv3 snowy but on the main tv only. The other two tvs are still perfect on all terrestrial and satellite channels. Anyhow I checked connections,all ok. Then I put the aerial cable from the aerial socket direct to the main tv, still the same problem? I thought the aerial socket into the tv might have a problem, but the telly is a year old panny and Rte 1, TG4, and the two satellite coax channels and dvd are all spot on. Funny thing also is if I watch the terrestrials through the dvd on the main tv the reception is perfect! I am baffled. I can manage with the way its working but I am just curious if anyone has a suggestion. thanks a lot. I do use a magic eye from the RF2 on one of the sky boxes. My reception is from Woodcock Hill. If anyone has any idea as to what the problem might be I would appreciate it. Many thanks

Its probably linked to the switch on of DTT (digital TV) tests in your area last week (41,44,47,51), which happen to be on adjacent channels to your analogue reception For RTE 2 and TV3 (39,42,45,49) , i.e. 41/42 and 44/45

Try retuning the channels on the TV. or adjust fine tuning. Your tuning may have been a bit off?

It could be a dodgy tuner, with poor selectivity, in your TV all along, which is only now giving problems when there are digital tests on nearby channels

If the tuner in the DVD recorder and your other TVs are all giving good reception, the problem seems to lie with your main TV.

Turn down the power in your masthead amp. Its pulling in DTT which is obliterating your analogue signal.

Thanks, could you clarify what the masthead amp is? Is it attached to the RTE aerial?

STB

Your aerial. What is it connected to ?

One of these ?


Or one of these


Or what type of amp are using on it ?

It should have a facility to turn up and turn down the gain on it. From what you have said it would appear that 1 Tv is only suffering which is the TV with an oversensitive tuner being overloaded. Find the masthead amp and turn down the gain a nodge.

Mine is a standard aerial wall socket which has been in situ for the twelve years we are in the house and probably ten before that.

Thing I cant get my head around is how I can watch the picture perfectly through the dvdr ultimately going through the same tv??!?

Anyhow,thanks for your advice so far. maybe I need to buy one of those things you showed? Although it may not be worth it if I can watch through dvdr and who knows the testing may stop or switch channels.

You have probably checked this numerous times but are the scart leads ok?

the OP said nothing about having a masthead amp.
Foggy43, the problem is RF not SCART

Sounds like the TV has a tuner with poor selectivity (Ch41 DTT affecting Ch42 analogue , and Ch44 DTT affecting Ch45 analogue)

As I said, try fine tuning (upwards) and see if that improves matters?

If you are fairly close to the transmitter it might be worth trying an attenuator on the TV's aerial lead:

try complaining to Panasonic if the above does not help, making the point that all your other TVs are unaffected by the digital transmissions on adjacent channels?

Thanks,everything ok with the leads.

Hi Just to let you know, I got a attenuator(needed the one with a variable setting) and it meant I could get both TV3,RTE2 and RTE perfect with one setting,adjust then for TG4. Obviously, the TV tuner must be sensitive as you say and screwed up by the DTT testing. Anyway, thanks for the advice.I had never heard of an attenuator before.Cheers!!

I'm having similar problems... for the last week (probably closer to 2 - don't know exactly) the picture on RTE2 is awful

I'm in an apartment complex and we've got some kind of shared system - combination of Astra2 and analog signal (I've got a freesat box working nicely off the sat signal)

I've tried re-tuning the RTE2 signal on the TV but no luck - I've also asked the apartment handyman and he says that there is no RTE2 in Limerick at all. I do find that hard to believe....

It sounds like whatever system the complex is using is also having problems with the DTT signals - what do people think? And what should I be getting the apartment handyman to do to get RTE2 back?

missed the champions league last night

slicedpanman

Anyone have any suggestions?

It does look like the problem is connected to the DTT trial (Woodcock Hill?) and its power levels... Practically every day RTE2 in unwatchable but last week, just for Thursday, it was a little snowy but watchable - I guess that the power was reduced on Thursday for some test or other.

TV3 is not really affected (can't say I ever watch TV3 anyway)....

Getting concerned that I will not be able to get to see the ManU match on Wed night

Can anyone here confirm that, in general, it is possible in Limerick to get a decent RTE2 reception? Also, can someone suggest what I should be saying to our apartment handyman to convince him that he needs to do something (and what specifically he needs to do) to get RTE2 reception back?
