Hi @pedrom, welcome to the community,
You wrote that ''__For the past days I’v been having a lot of problems with my TV signal. Sometimes it’s bad and most of the time is no signal at all." Are all the channels affected?
I suggest you verify the TV cable of your television. Depending on the quality and the length of the cable, it may cause losses of the TV signal in some frequencies or in all the frequencies.
Regards,
Michael
