Lack of Polsat and TVN channels on TV set with DVB-T2 decoder - signal from Sleza, Wroclaw, Poland

I have recently bought a TV with dvbt2 and have an aerial receiving dvbt2 signal but when searching for channels it only shows all tvp and possibly Doba tv but does not search for any Polsat or TVN channels. The signal is received from Sleza Wrocław (Lower Silesia). It is about terrestrial television, of course, what can be done to get access to these channels.

On some TVs/tuners you can select whether to look for Dvbt2 or just Dvbt maybe you have something wrongly selected here.
You don't write a word about the antenna installation and it's important if everything was received before (before Dvbt2) or if there were problems.

I used to have all the channels of TVP, Polsat etc. After DVB-T2 came in, of course they stopped working, so we changed the TV for a newer one, but it still doesn't search for these channels. However, to answer your question, in the same place where the aerial stands a year-2 years ago they were receiving normally

See manual search.
Which antenna?

I don't know why, but some TCL and Thomson TVs are still sold with dvb-t2 blocked for Poland.
You have to go into the service menu to unlock this option with code 6425. You have it described among other things in this topic - Link .
After that, you will most likely have to scan the band automatically, because on a manual scan the TV may still "not see" channels in dvb-t2.

We have changed everything as you posted in the previous topic and still unfortunately there is nothing in the automatic and manual scans.

Added after 56 [seconds]:

It seems to me that it is not the fault of the antenna, because we have taken various antennas that receive normally, but in this particular TV set it does not.

Strange. Among the reviews of this model on the ME website I found ...

The DVB-T2 tuner works smoothly and quickly ...

In the configuration settings of your TV try to change the region to Czech Republic or Germany.

Where did you receive these antennas correctly - at the TV location or elsewhere? Have you verified reception at this location on another receiver, e.g. an external decoder (this is probably the easiest way)?

Hi. Reset t.v. to fabulous, then czech, search and laughs....
Ps. as long as the antenna has range😊.

In post #3 you write that everything used to receive correctly from this antenna, i.e. the installation is good, whereas here you write that you tried different antennas.
If you actually unlocked DVB-T2 on the TV, as stated above, or selected the Czech Republic or RFN region, it should search for channels and that's it.

If it doesn't search, the problem could be with the antenna, for example, it may have an amplifier and need power, but it's not plugged in.

P.S.
Mux3, i.e. TVP channels, now searches after antenna changes, or does it not search.

Tuner sensitivity on TVs and set-top boxes also varies. Plugs and cabling also important....

How far are you from Sleza ?
What town ?
Are you using antennas on the roof ?
What kind of antenna is it ? (some photos)

Maybe instead of Sleza you catch Zurawina (506MHz, k25 ) and then you have only : TVP1 HD, TVP2 HD, TVP3, TVP Info, TVP Historia, TVP Sport HD. and if they work correctly - then DVB-T2 also works correctly

I have about 10km to Sleza, Gogolow. When I give manual search I have 506 KHz. I do not have antennas on the roof. Yes, TVP Historia and Sport are there which means from your words that DVB-T2 is there. The antenna amplifier is connected. I guess I'll have to buy a more powerful antenna, although this one should also catch, because theoretically it had a range of probably up to 15 km

Then you should be able to see the transmitter.

506 MHz is mux-3, which is DVB-T , not any dvb-t2. What signal parameters do you have on this channel? Have you tried changing the Region/Country?
If you receive mux-3 from Sleza, then theoretically you should be able to receive the other muxes in dvb-t2. Unless, however, you have not unlocked this standard in your TV or you have a crap installation.

So what kind of antenna do you have and where is it mounted? Is it a room antenna with an amplifier? Antennas have no such parameter as "range". It all depends on the reception location and local reception conditions.

10 km from the transmitter and amplification.... With a strange antenna...who knows what kind of antenna...and maybe next to the rutetra what sow....
Ps. On the " nail"😁 in the socket will peel the signal at 100kW from the transmitter. Well unless it doesn't catch tv however the new dvbt2...😢

Well, that's right !!!

Room antennas with amplifier clog up (TV head overdrive) with such a strong signal, especially with DVB T2
Stick a piece of wire about 30cm into an aerial socket and see what the TV catches.
Here's a list of what you should be able to pick up at your place
http://www.sat-charts.eu/nadajniki.php?id=MWlrN2cmNHI0MjU=
Clicking on a particular transmitter in the table will show you all the reception parameters and what programmes are available

In my opinion, judging by the posts of the creator of the thread, the unblocking of the TV as advised at the beginning of the thread has not been done. The creator did not select the region of Germany or the Czech Republic, but continues to use the Polish location and the installed antenna. In addition, he placed the antenna amplifier 10 km from one of the best transmitters in Poland (the second one in Kielce - Święty Krzyż).

Why is there an antenna with an amplifier there?

Good film. But there directional antennas. Maybe here a biquad antenna is enough...or a small "net" with symmetrizer.😉
Ba, we still do not know what kind of antenna at the author of the topic.

Ideally, the author should take a photo of the antenna and show us. It will be easier to advise something.

Because so it is not clear where the problem lies, whether in the antenna installation or in the TV.

Reinston EAN002 antenna, I entered the code 6425 changed to dvbt2 on, gave chechy a turn off the TV and scanned, still the same

I wouldn't call this an antenna. It is rather an expensive antenna-like gadget. To tell the truth, I have never yet managed to get stable reception on all muxes on such an invention.
In your location it should theoretically be possible to receive on an external antenna with low gain and dimensions, e.g. M-Log 6-69 or similar.
If "maid", then APOK passive version.

In the TV's configuration settings, try changing the region to the Czech Republic or Germany.

I'm joining the topic because I also have a problem with DVB-T2 (not) working on my TCL TV. Only that I have a rather newer model, after the 65P635 bought just about a fortnight ago.

In Swarzedz near Poznan I only receive MUX-3 from Piatkow, and when I try to set - also manually - the other multiplexes from the surrounding transmitters, it shows me signal strength and quality at 0%.

I have already applied the procedure quoted here with entering the service menu before code "6425". There I changed the DVB-T2 setting to "ON". I then switched the TV off and on from the remote control. And it still does not find DVB-T2 channels from the surrounding transmitters. I still only have MUX-3 from Poznan, which I think is still broadcast in the old standard until 14 or 15 December. It's also a fact that after changing the setting in the service menu I haven't yet done a "full" reboot, just a switch-off and switch-on.

As for the second tip occurring here, i.e. changing the region to Germany or the Czech Republic, when I enter this setting, the TV asks me for the password. "6425" doesn't work here, so I can't change the region for now. Any idea how to access this setting?

Or do you have any idea why changing the setting in the service menu had no effect?

It will tell me a lot if I change the standard to MUX3 in a couple of days' time, because then I'll definitively see if the problem is with coverage/power/signal reception, or if the TV just doesn't see anything that's DVB-T2 standard.

[UPDATE:]

I finally got into the region settings via the password "1234" (a few tries and it went in... just don't know why they even put a password on there). And the end result is that neither the change in the service menu nor the change of the region did nothing in terms of downloading multiplexes broadcasting in the new standard (it is still 0%). I am very surprised that the indoor antenna, which provides images of excellent quality from Piatkowo in Poznań, is not picking up anything from Śrem (some 20 km more distance and 5 times higher transmitter power) and shows 0% signal strength and quality. In this situation I have restored the TV to its initial settings, because rather a new receiver should already have everything set up correctly for Poland. If in the middle of December it will stop receiving even MUX-3 from Poznan, then the direction of "TCL service", and if from 15 December it will still be collecting nicely from Poznan, then I have to hit some antenna service and let them fix me something nice, which will give me more than just public TV channels.

So far, after using code 6425, I have always been able to unlock and tune the dvb-T2 muxes - both on TCL and Thomsons. Except that usually in order for the TV to "see" them, I did the first tuning on automatic, because in the manual search option the TVs still did not detect the signal.
Another option - in your location the maid simply does not receive the signal from Srem. Other transmitters are not reachable. Piatkowo and AE transmit mux-3 and mux-8 in dvb-T.

Try putting the antenna out of the window or mounting it on the balcony. This antenna can be used as an outdoor antenna.

I suggest you continue the thread in the topic you set up.

That concludes my topic in this thread thanks for that above comment. It wouldn't have occurred to me to "blow" that antenna outdoors, and that might be some test.
