Switch them all off, and plug them back in one by one to see which is causing the problem. Regardless of their frequency, these can all have the potential to cause problems if they’re in close proximity to your TV. Computers, Wireless Routers and modems, cordless phones and big AC power adaptors used by some electrical items are all things to check when searching for a source of interference. There are plenty of everyday items which can be a source of interference for your signal. F-Type connectors are best (these are the screw in type ends which are also used by Foxtel and Telstra) as they give the most secure, firm connection.
You should use an RG6 Quad Shield Antenna cable for minimal signal loss – these are not that expensive and can be purchased from any retailer or electronics store. In a lot of cases, these are old, thin cables with minimal shielding, and this is a classic reason for signal loss. If your reception issues are due to interference, as in most cases, then the first thing you should check is the antenna cable between your television or set-top box and the wall socket. These usually also have a gain adjustment which is very important, as a signal which is too strong can also cause a TV signal to break up. If you must use a splitter, make sure to use the powered digital antenna boosters from brands such as Kingray. These are not powered, but just a white plastic box which has a little board inside and the cables are just held by clamps. Boosting it back up to its original strength at both points will certainly be the right thing to do, and this is exactly what signal boosters are made for.Īlso it would be a wise idea to remove any old signal splitters that are currently in use, as these may also play a part in signal loss – particularly if they are the old “passive” type. interference free) to begin with, but when it is shared across two TV tuners it drops to a level which causes break up or loss of signal. This means that the signal is clean (i.e. Therefore, you should do everything you can to reduce interference and improve the quality of your signal before you try to amplify it, because most of the time you’re just amplifying your interference too.Ī booster may work great if you are running two or more TVs in the house from the same antenna and the shared signal between the two drops as a result. Most Digital TV Signal Interference issues are not caused by weak signal strength, but rather interference. Using an amplifier from places like Dick Smith or Jaycar might work if there is a slight drop in reception on some channels, but it’s quite likely that you will make the problem worse. The stronger the signal, the better the result, right? Not really. On paper, the thought of boosting your signal seems like a logical step to take. There are plenty of scenarios to try first before resorting to that expense. While the solution may sometimes have to be a new Aerial, it isn’t always the only option. There is no middle ground a less than perfect signal can leave you with no image at all!
CHANGHONG LCD TV GETS LOTS OF INTERFARENCE UPGRADE
The upgrade to digital eliminated these issues, but (unknown to many) the downside is that you generally have a perfect picture – or NO picture at all. Annoying as that may have been, at least the image was still watchable if you were desperate enough.
In earlier days of analogue TV a poor signal would result in a fuzzy picture or ghosting. Here are a few basic approaches to take before hitting the panic button. On a daily basis, TV salespeople are dealing with customers returning their TVs citing faulty tuners – as they are unable to tune in any or all of the Digital TV channels.
