Missing chain 4,8,15,16,17
Solved
Hello,
I bought a TCL TV two months ago, and I have recently noticed that I do not have access to the following channels: 4, 8, 15, 16, and 17. Of course, I have performed an automatic scan that didn’t change anything. Do you have a solution? Thank you.

Hello,
Start by checking the coaxial connections, unplugging and replugging them several times to eliminate any possible oxidation; if necessary, redo them properly. Be careful, even the slightest "hair" from the braid touching the copper center can mess things up...
The antenna may have moved as well...
The HD TNT is more demanding in terms of both quantity and quality of signal.
If there's still no result, the best option would be to place a variable gain pre-amplifier (sometimes too much amplification can degrade the signal); this preamp should be LTE/4G filtered and placed as close to the antenna as possible.
Here’s a good product for example:

Thank you for your response, we changed the antenna cable and it worked. I'm surprised that some channels were working and not others. Thank you very much.
