Brazil. The year began with digital TV available in 100% of Brazilian capitals. There are already more than four thousand cities adapted to technology that, among other benefits, brings more image and sound quality to open programming. This means that distortions or rainfall in the video will become increasingly rare.
But, to enjoy these resources, it is necessary to check if all the equipment behind the TV works correctly. Otherwise, signal problems can take over the air programming either at the time of that important play of the football game on Sunday, or during the transmission of the last chapter of the novel.
Most often, it is necessary to check the equipment used and the installation of the antenna, since the digital signal is quite stable. Therefore, take a look at the suggestions of experts from the Brazilian Digital Terrestrial TV System Forum, SBTVD Forum, to diagnose or even solve the problem.
Observe the area
Find out with the neighbors of your street or the condominium where you reside and who attend the Digital TV if they are also with the same problem (loss of signal). This part is fundamental to understand if it is a problem in the region or only in a residence.
Check cables and cables
Check if the coaxial cable (between the antenna and the TV) is broken or disconnected from the antenna. Check if the antenna cable is connected to the TV at the correct input. This can be confirmed on the back panel of the TV. The antenna input is indicated by one of these words: ANTENNA IN; VHF/UHF; RF IN.
Do channel search
If you do not know how to perform this procedure, refer to the manual or contact the manufacturer of the TV. Every time the position of the antenna is changed, it is necessary to perform the search for channels on the TV.
Check the antenna
If with the internal antenna these procedures do not work, the ideal is to contact a trusted antenna to install an external antenna and check again the points related above (connectors, cables, etc.). If it is a condominium, the ideal is that the trustee or concierge contact the antenna to verify the conditions of the collective antenna.
