Hi guys, I'll try and keep this as concise as possible, but here is my problem. I have NTL and have been running a digivox 2007 for some time now in my front room and bedroom (3 way splitter used as I have broadband also) The box in my front room has always worked fine, but the upstairs box never had all the channels for some reason. Even if it scanned them, it never displayed a few like itv2 and bbc2. However, I purchased a Eurovox EX5000 PVR, and although it scans all the channels and constantly shows a signal strength of between 82 and 86, the picture and audio break up and and make it unwatchable. I removed all the splitters and wired the cable straight into the Eurovox, to check that way, but no change. I then took the box round a friends house to see if it was at fault, and it worked fine. Has anyone else come across this kinda problem and know of any fixes?
hi mate its prob your cable running to it have you checked to see if there is any stapples in it if they have ran it round your skirting board or ran it tight from the splitter check the bends in the cable because sometimes around doorframes and that its really tight and that can cut the sig a little bit.
Nah, can't be that as I took all my leads with me when I plugged it into my mates house. I personally think it must be something to do with the NTL junction box at the end of the road, but am unsure if they can turn up and down power.
Itstheh, I have a similar prob with father in laws. ex5000 worked fine here when i set it up for him, but when i installed it at his house a couple of miles away it did not pick up many channels.Even Beebec and eyeteev break up! The cable was only installed last week. I am trying to get to the bottom of this prob. I have put a booster that he had lying around, on it. Then it picked up a few more channels but most of them were poor quality and break up! I have done a power rescan, phoned tech, and am now about to try to get the line in moved up the peg in the box if poss! ( to see if this will boost the signal) Some channels with 82% are breaking up, but on my box here they are ok at that strength. When i phoned tech they said there was no booster on this box as it was a different receiver and does not need one. Has anyone got info what to do next as it does not appear he can use this box at his home? Next thing will be to reinstall the firmware! What else should i try? Any ideas guys? Perhaps a tv booster of some kind, as the one i have at the mo aint doing much.
Hi Sc0user, What is a variable attenuator ? Where can i get one? Is there one specific for cable, and what do u do with it! My father in laws ex5000 is direct into the cable with a f con on the end, and it struggles to work. ( not many channels and some are garbled mixed up channels. Mine works ok but has a splitter on it! (His box worked at mine ok too!) Is this what u mean? http://www.maplin.co.uk/Search.aspx?criteria=variable attenuator &source=15&SD=Y When the cabl man came out and tested the line, it was a 3 he said that was good. Cant make my mind up if the sig is too strong or too weak! With the booster on its a 85% with it off its a 72% but at mine its a 79% and works fine. Heres a link below to the screen shot of garbled channel. http://www.4shared.com/file/56004680/39fcd8c6/DSC00469.html?dirPwdVerified=2a8d4ac3
Sc0user, I tried the variable attenuater and no joy . Any other ideas mate? It may need more signal, as less did not work!
Anyway i did and this did not work so regardless i can cross this off the list. No blame intended, just need to find a resolution. Thank you for your input so far! I cant ring up cc and say my eurovoxex5000 is not working properly here, can u do something because i cant pick up channels i aint supp to av.
None taken, if you look that post you quoted was intended for the poster before you. Your fault is purely to do with the cabling at your house.
one always overlooked possibility is what is known as co-channel interference. Breakthrough of a local strong signal into cables and wiring. there are usually a couple of analog channels fired down cable feeds.. at least c4 and itv. I suffer exactly the same here with interference from the local taxi office making 40% of my channels unwatchable in the evenings. You can see the effect as herringbone pattern across the whole screen of an analog tv. It could be the cable at fault, perhaps it is even coming down the mains , or the box.. if one channel or channels are much stronger than the others they can cause overloading of the input stage of the box leading to very similar symptoms which is why the attenuator was suggested.. I have seen cable boxes wrapped in tin foil before now to cure these problems... Roll on the digital switchover.. you could still watch things with pretty bad co-channel interference and electrical noise with analog (what I have to do to watch itv/c4/5), but this digital stuff... forget it.
Are you in a simulcast or purely analogue area varnull? I understand the theory in relation to cross channel interference but most of the time its usally the internal wiring which tends to cause this symptom in relation to the OPs problem. However you cross channel information have very good foundings but you may be invaded sooner than you think, dependent on your location http://entertainment.timesonline.co.uk/tol/arts_and_entertainment/tv_and_radio/article2866178.ece
