DVB-T Decoder WIWA.265 Not Searching for Channels: Collective Antenna & MPEG 4 Issues

Good morning
The purchased DVB-T decoder WIWA.265 does not search for any channel. The decoder has just been purchased and is well connected according to the instructions. The antenna works directly to the TV but the TV does not have MPEG 4 so it does not receive most channels. Hence the decision to buy a decoder which, unfortunately, does not search for anything at all. I live in a block of flats and a collective antenna is installed here, so I have no direct control over it.
What may be the problem? The decoder is brand new, so I rather exclude its damage.

The fact that it is new does not mean that it is working - see the search modes of this - all channels, turn off the antenna power and as a step zero make sure you have the correct country set ...

I have tried probably all possible combinations with these settings offered by the configuration tool during the first run. Country Poland, all channels and free only, manual search, antenna power on/off. I've exhausted all possibilities. According to the instructions, after searching for channels, it should immediately throw me to 1 channel in the list, because nothing is found, it throws me back to the configuration tool, and so on. I even updated the decoder software which was successful and still the same. It seems as if the antenna is not detected at all.

Check the decoder at your neighbor's, find out what signal is in the antenna cable... - and if there is...

The signal must be there because the cable directly connected to the TV works.

But perhaps the antenna is providing an analog or cable signal. So the decoder has nothing to receive. So a piece of wire will solve the problem (I don't know anything about the pickup location).

The cable signal is not received by the decoder? There must be a cable signal here because it is a block and I have both the internet and the cable from the antenna connected to the same socket in the wall using some kind of splitter.

I have no idea what cable is like here because after moving in here I just connected the TV to the wall socket and the TV received about 30 channels and since I don't watch TV often, I left it as it is and I wasn't interested at all where this TV and why. The problem appeared a few days ago because the TV that received these channels broke down. By the way, in a strange way because the connected matrix does something like a short-circuit and the TV turns itself off immediately after turning on. I had a second TV set, a bit older, which does not receive MPEG 4, so I quickly bought a set-top box without going into details whether it will pick up the cable signal. I'm trying to find out what cable is in use here. Maybe today I'll be able to get a regular antenna and see if it picks up.

And what city / how far to the transmitter?

Case solved. Connecting a regular antenna also works, it was actually a problem of an inappropriate decoder. All that remains is to set it properly in your free time because it loses the signal. Thanks for the help, especially those who made me realize that such a decoder does not receive cable.

Rather, it is a problem of inappropriate selection of these three elements: the signal, the TV receiver and finally the decoder. As you can see, the antenna will reconcile the receiver with the decoder. And the most effective solution would be to purchase a receiver adapted to receive AV, cable (maybe also satellite) and DVBT T2 signals, taking into account the antenna in question. But on the other hand, in the current situation, when there is a decoder and a receiver, it can and can function in such a configuration. The more that you do not declare excessive attachment to the TV.

Are there any that reconcile these two things? From what I initially looked at online stores, there is either DVB-T or DVB-C (those, as I guess, support cable), but I have not seen one that connects it.

Thanks, if I can't position the antenna well enough, I'll return this decoder and pay extra for one that also receives cable.

But how can you be sure that you are getting a cable range in the outlet?

He concludes that it works on a regular antenna. There are probably no other options. In addition, I found information that my estate is connected to the cable from the company alfa system.

Hello. I will join the topic. The Samsung ue32h5000wxxh TV set from 2014 does not remember the channels searched through the dvb-t / t2 decoder. I updated the software to version 104..... from 2016. I would like to mention that without a decoder, directly from the antenna, it is fine. The TV searches for and stores channels. When connecting the decoder with an HDMI cable in the menu, "broadcasting" is not active. When searching channels by decoder and TV function, it searches but does not store. Please help. Casimir.
P.S. If something is not clear, please ask. I'm a layman in these matters.
In the meantime, I received information that the decoder remembers the channels. I contacted samsung support. It didn't do anything.

And why should the TV remember channels if an external tuner scans them? The TV serves as a monitor for the tuner.
Think before you write something.

connect the antenna to the decoder.

He didn't mean it, he thought that the programs from the decoder will be added to the list of programs on TV.
The decoder is a separate device, so it will be able to use it on the TV only through the HDMI INPUT by switching to it and nothing else.

I don't understand how it happens, what it remembers and what it doesn't. The fact is that I don't have TV over HDMI. Connection: antenna cable to the decoder, from the decoder to the TV via HDMI, the selected HDMI signal source and the decoder shows the message start updating, the TV remote control menu works and I see that "broadcasting" is not active. only with the buttons of the decoder I can change the backlight of the horizontal lines with subtitles (I will try to attach a screenshot). Switching to the TV signal source, I have the "broadcasting" button active and I can search for channels. After tuning, I go to the channel list, I get an empty list message, and the question if I want to search for channels, and it happens over and over again. I don't have exact instructions in the attached leaflet of the decoder. Thank you very much for your comments. celgz

Search for channels with a set-top box, not a TV.

It's already been written. You manage the received programs in the set-top box. The TV receiver is only a passive monitor of the tuner signal. So you won't find anything there (except the input source selection in this case HDMI) and leave the menu alone. You search for channels, organize them and select them for presentation in the decoder/tuner (also decoder pilot).

Thank you, problem solved. While solving the problem, there was a moment when I used the set-top box remote control, but it didn't work for me, so I went back to the tv remote. After today's hint, I went back to the set-top box remote control. It has been confirmed not to work. However, knowing that it is the only right way. The remote set included two new batteries that I put in the remote. I was sure the new one was working. And here it turned out one of them has 0 V. I replaced the faulty one and everything is fine!!! Thank you very much for guiding me to the correct solution to the problem. Best wishes. Celgz.

Hello forum users. A new problem has arisen. After overcoming the difficulties with the channel search by the LXDVB1 decoder, it turned out that the image on the TV is expanded. Setting the TV to different picture types does not work, i.e. it is widened all the time. Directly from the antenna everything is fine. I replaced the decoder with LXDVB101. The picture is correct but I only have 15 channels. Many basics ones are missing, e.g. TV 1, TV 2, etc. I am asking for help, because it is described incomprehensibly in the manual. Thank you very much in advance for your help. Casimir.

Earlier you wrote that you still need to set up the antenna.

The previous decoder LXdvb1 searched for all channels. I conclude that the antenna is positioned correctly. Directly from the antenna, the TV searches for and plays all channels. Casimir.

I am weak in technical matters. As a test, I send pictures of the TV1 and TV2 signal (among other things, I miss these channels through the decoder after replacing LXDVB1 with LXDVB101. Let me remind you that on the previous decoder there were all channels, but the image was extended. The splitter has one input and two outputs to which TVs are connected. One plays without a decoder, the other via a decoder. Maybe this connection is wrong?
