Digital terrestrial: how to solve the most common problems
Digital terrestrial
Today, March 8, the first step of the switch-off of the transition to the new digital terrestrial Dvb-t2 took place with the transmission of the TV channels which now compulsorily adheres to the mpeg4 (h.264 - Avc) encoding. As happened in the past on the occasion of the previous switch offs, even today many users could encounter various malfunctions that compromise the normal use of TV programming. Here is a series of problems and related practical solutions.What to do if the signal is poor or absent and the channels are not seen The most widespread and serious problem. With the old TV it was possible to orient the antenna to switch from the famous snow effect to a gradually clearer reception, but with digital terrestrial if the signal is not sufficient then the screen becomes black. The first step is that of a first retuning, from the internal setup / configuration menu: if a pin code is requested, it is usually "0000" or "1111" or "1234".
So, check the antenna cable, a detail often overlooked: it is always better to prefer thicker and less flexible ones which, although less comfortable to install, guarantee less signal loss. The cable must be as "extended" as possible, especially near the antenna connector to avoid damage over time. Furthermore, it is better that the antenna cable is not routed inside a bridge device such as a digital recorder which in addition to causing quality losses can also go into energy saving mode by lowering the yield. It is also good to check the status of the connectors and inputs of the television.
After checking the cable and connections, it is advisable to re-tune the channels again from the settings / configurations menu, if necessary proceed with a factory reset of the TV and decoder and if the problem persists then it concerns the system. In this case the do-it-yourself is more complicated, because the practice would require the use of a professional tool such as a field meter to understand if the antenna is placed in the wrong place. Furthermore, the antenna technician can check if the signal level that reaches the house is within the minimum limits.
How to fix audio problems Another noteworthy detail is that of audio problems and the cause it can gravitate around the Dolby Digital standard, which creates conflicts on cheaper TVs and especially on high definition on-demand content. A possible solution is to use the coaxial audio output and choose the internal audio setting to stereo.
How to understand if the TV is ready for the new digital terrestrial As we have explained to you in more detail, after having carried out the retuning you can carry out a compatibility test divided into two parts. In the first, you connect to the Rai channels 501, 502 or 503 (those in high definition) and if the signal is displayed correctly and you see the HD logo then the tv / decoder are correctly equipped with the coding chip of the mpeg 4 standard, while for also check the predisposition of the hevc main10 signal for the next switch off in January 2023, it is possible to verify the correct display of the Rai or Mediaset test channel respectively at numbers 100 or 200.
If after all these procedures the problems persist , then the simplest solution is to focus on a decoder compatible with the new digital terrestrial. If you are looking for models to focus on, here is our choice of the best dvb-t2 decoders, the variants for those looking for more such as those that also offer smart functions (such as streaming apps such as RaiPlay, Netflix or Prime Video ) and the more compact and economical products that can be hidden behind the TV. Finally, here are those with immediate shipment.
